[Dovecot] ot: tracking messages- luser troubleshooting

I had a user complaining of 'not getting emails' I've searched for sender in maillog, got two messages, both showed up as; Dec 12 15:51:29 emu postfix/pipe[9607]: 3F21C5E750: to=<xxx>, relay=dovecot, delay=6.4, delays=6.3/0.01/0/0.12, dsn=2.0.0, status=sent (delivered via dovecot service) Dec 12 15:51:29 emu postfix/qmgr[20178]: 3F21C5E750: removed yes the user claimed the message was not received, eventually, after traversing through severl directories, I found the message in '../Maildir/.Deleted Messages' it turns out it was inadvertenltly deleted on iphone. there has to be a better way to try to find / resolve such issues ? what's an optimal way of trying to trace such? I greped for the 3F21C5E750 string through several Maildirs tia,

[Dovecot] Dovecot as caching proxy
by Anton Lundin 12 Dec '13

12 Dec '13

Hi. I'm bin playing around with dovecot to try to setup it as a caching imap proxy. I manged to get dovecot to use both proxy=y and imapc: connections to the master server, but i haven't manged to get dovecot to cache any mails. The remote imap server is a quite hostile one, that i don't have any super/master user access to, and it only exposes imap. I've used tried both with the static passdb, nopassword=y, and imap authdb and with static and prefetch userdbs. I manage to produce the same results, eg. dovecot grabbing the password from the client and uses it to establish a imapc connection to the server and re-exposing it, and starts to write indexes. ( The later plan is probably to use pam as passdb to grab a and store a hashed copy of the password to allow offline access to the cached emails, but thats a later problem to solve.) What i haven't managed to get working is to trigger some replication of the remote emails to dovecot and using that as a cache to serve the emails to the client. I found some presentations and some emails that point in the direction that this should be possible to achieve, probably with the replication plugin, but never managed to get this to work. I'm using dovecot 2.2.9 Does anyone have manged to produce a working setup like this? //Anton -- Anton Lundin +46702-161604

Hello. This might be a silly problem, but I'm a bit a newbie at this, and the internet didn't give me a solution to this yet. I installed a mail server with postfix, dovecot, postfixadmin and a mysql DB for authentification, using this tutorial : <http://www.exratione.com/2012/05/a-mailserver-on-ubuntu-1204-postfix-doveco t-mysql/> http://www.exratione.com/2012/05/a-mailserver-on-ubuntu-1204-postfix-dovecot -mysql/. Except step 4. The complete tutorial worked on a virtual machine, but doesn't work here on a vps from ovh.net. Connecting via telnet localhost 143 works, I can connect. When I try to connect via thunderbird, the domain name is picked up, but gives me a bad login/password combination. Mail.log, mail.err and error don't show anything. Via MS Outlook, I seem to get stuck on the connection page, and I get the following errors in mail.log: dovecot: imap-login: Disconnected: Too many invalid commands (no auth attempts): rip=x, lip=y dovecot: pop3-login: Disconnected (no auth attempts): rip=x, lip=y dovecot: imap-login: Disconnected (no auth attempts): rip=x, lip=y, TLS: Disconnected dovecot: pop3-login: Disconnected (no auth attempts): rip=x, lip=y, TLS: Disconnected dovecot: pop3-login: Aborted login (no auth attempts): rip=x, lip=y dovecot: imap-login: Disconnected (no auth attempts): rip=x, lip=y, TLS: Disconnected dovecot: imap-login: Disconnected (no auth attempts rip=x, lip=y dovecot: imap-login: Disconnected (no auth attempts): rip=x, lip=y, TLS handshaking: Disconnected dovecot: pop3-login: Disconnected (no auth attempts): rip=x, lip=y, TLS handshaking: Disconnected And after a while asks to try to connect via plain method. Doveconf -n gives me this # 2.0.19: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-042stab068.8 x86_64 Ubuntu 12.04.2 LTS simfs auth_mechanisms = plain login first_valid_uid = 150 last_valid_uid = 150 mail_gid = mail mail_location = maildir:/var/vmail/%d/%n mail_uid = vmail passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } protocols = " imap pop3" service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-userdb { group = mail mode = 0600 user = vmail } } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } Hope you guys can help me, and thanks in advance for it.

[Dovecot] multiple passdbs and auth sockets

[Dovecot] Selectively allow non-SSL connections based on userdb
by Trent Lloyd 12 Dec '13

12 Dec '13

Howdy Folks, I am considering transitioning our mail service over to SSL-only. As a transition mechanism, it would make sense to force all new accounts to use SSL, but still allow old accounts to go unencrypted until some transition date passes. I have done some extensive searching but could not figure a mechanism through which I could specify a setting for this in userdb or similar. Does anyone have any ideas that doesn’t involve a post-login script? Thanks, Trent

[Dovecot] Plugin development - ostream and index cache size
by Philipp Brüll 11 Dec '13

11 Dec '13

Hi, I'm new to this list, so first thanks for the dovecot tool! So far, it has been great to work with. Currently, I'm developing a scrambler plugin for dovecot, that should stores the mails encrypted. To do that, I've created the scrambler_ostream and scrambler_istream that does the encryption and that I hook in the mail storage process. The scrambler_ostream is stacked on top of the output stream of the mail_save_context (mail_save_context->data.output) and the scrambler_istream is attached to the input stream when the virtual function istream_opened in the mail_private struct is called. Basically, the encrypt/decrypt works, but during the process the data size changes slightly. And when I'm doing a FETCH BINARY[] via imap, it results in the error... Cached message size smaller than expected (204 < 208) Error: Corrupted index cache file /home/.../mail/mailboxes/INBOX/dbox-Mails/dovecot.index.cache: Broken physical size for mail UID 1 My guess is, that the FETCH function tries to deliver the unencrypted cache version of the mail (204 bytes) and not the stored version (208 bytes). How can I make dovecot cache the output of my scrambler_ostream or at least disable this caching for testing? I've read already a lot of code, but I've found a hint yet. How does - for example - the zlib plugin handle this issue? I have read the code a couple of times, but still have no clue. Best regards, Philipp

[Dovecot] OT: Large corporate email systems - Exchange vs open source *nix based
by Charles Marcus 11 Dec '13

11 Dec '13

Hello, There has been some whispers about considering migrating our mail systems to Exchange Server. I want to try to nip this in the bud. I would like to ask for some help with providing some kind of comparison of large(r) commercial companies use of email systems... specifically, those using Microsoft Exchange Server, vs those using open source Linux/Unix based systems, including even commercial *nix groupware based systems like Zimbra, as well as plain mail systems like dovecot, or cyrus or courier. I know that many (if they are smart) Admins that do use Exchange internally will use postfix (or something else linux/unix based) in front of it as their relayhost (for both inbound and outbound), so just counting the number of publicly accessible smtp servers won't be a good gauge. Does anyone know of any decent non-biased studies that have been done, hopefully relatively recently (last few years) that provide such a comparison? Thanks, -- Best regards, */Charles/*

[Dovecot] "Select Inbox" drops connection. IMAP troubleshooting help available?
by Thor Legvold 11 Dec '13

11 Dec '13

Newbie to the list here. I don’t know if this is Dovecot specific, but I can see that my IMAP server is running Dovecot. So far (as a client) I haven’t been able to figure out how to get it to tell me the version number. What I’m trying to get is more detailed info in order to debug an IMAP problem. I’ve been unable to retrieve email since the 27th of November on this specific account. Another user on the same domain/email receives and sends email just fine. Having tried both Apple Mail, Thunderbird, as well as a Telnet terminal connection, I see two problems, but am unaware of what to do from here to verify or fix the problem. First is that the SSL certificate is a self signed one from some local hosting service. Fair enough, I told OS X to trust it (for now), both in Mail and Thunderbird (and Safari). Second is that when logging in via the terminal, I can log in fine, navigate to any folder and read any email on the server - with the exception of the Inbox. Anytime I issue a “Select” or “Examine” command with the “Inbox” as argument, the connection is dropped. E.g.: after logging in, listing folders, navigating around, I do this: a select inbox closed Sonovo:~ Thunder$ and am back at the terminal prompt. If I do an “Email Trace” in CPanel on my server (hosting both my website and IMAP email accounts), I see a long list of emails accepted to my address and in the system, but I cannot seem to access them from any client. There may well be a better list/forum for discussing this kind of thing. I was actually on a mailing list years ago with Mark Crispin himself, but haven’t spoken with him in 10 years or more. I’m not sure where to go for more help/info. I’m not a complete (l)user, but nor am I a guru (tm). Any tips or help is greatly appreciated! Sonovo

[Dovecot] undoing a zlib test
by Terry Barnum 10 Dec '13

10 Dec '13

I'm trying to undo a dovecot zlib test and uncompress 6 emails in my Junk mailbox. There are about 25 total in different mailboxes but I thought I'd first start with those in my Junk. I ran: # dsync -v -u terry(a)dop.com -m Junk -o plugin/zlib_save= backup maildir:/path/to/temp/folder which returned without error and backed up my Junk mailbox but didn't uncompress the 6 emails. Am I calling dsync incorrectly to uncompress? zlib is currently not loaded as a plugin. Once I get them uncompressed is doveadm import the correct way to get them back into my Junk mailbox?

[Dovecot] dsync verbosity, summary of transfer
by Alan McGinlay - SICS 10 Dec '13

10 Dec '13

Hi! I am playing with dsync and trying to fix an issue I have mentioned in another thread (subject: "Re: [Dovecot] Dsync error: Couldn't drop privileges: getgrnam") and feel that dsync could use some additional informational output. It would be particularly helpful while experimenting with a migration if it could output a transfer summary and / or log separately. A summary could be similar to that which imapsync outputs after completion, for example: ++++ Statistics Transfer started on : Thu Dec 5 20:30:05 2013 Transfer ended on : Thu Dec 5 20:32:00 2013 Transfer time : 114.3 sec Messages transferred : 7 Messages skipped : 766 Messages found duplicate on host1 : 0 Messages found duplicate on host2 : 0 Messages void (noheader) on host1 : 0 Messages void (noheader) on host2 : 0 Messages deleted on host1 : 0 Messages deleted on host2 : 9 Total bytes transferred : 71820 (70.137 KiB) Total bytes duplicate host1 : 0 (0.000 KiB) Total bytes duplicate host2 : 0 (0.000 KiB) Total bytes skipped : 10070561 (9.604 MiB) Total bytes error : 0 (0.000 KiB) Message rate : 0.1 messages/s Average bandwidth rate : 0.6 KiB/s Reconnections to host1 : 0 Reconnections to host2 : 0 Memory consumption : 90.5 MiB Biggest message : 39274 bytes Detected 0 errors

[Dovecot] Dovecot+LDAP lda problem
by Zeljko Culek 10 Dec '13

10 Dec '13

Hello everyone, I need some help with Dovecot+LDAP config and local delivery. We're using Dovecot 2.0.9 on Centos 6.4. Before, we used Qmail with the same LDAP. Our LDAP accounts have the attribute deliveryMode which we used for mailing lists (OK, they are in fact mailing groups rather than lists). When the attribute is set to deliveryMode = nolocal Qmail did not deliver mail to the list mailbox, only to the accounts on the list/group. Now with Dovecot(+postfix) I can't achieve the same behaviour. Can Dovecot be set up not to deliver the mail to the list mailbox if the list has the attribute deliveryMode = nolocal? This is my /etc/dovecot/conf.d/dovecot-ldap.conf.ext hosts = xxx.xxx.xxx.xxx auth_bind = yes dn = cn=admin,dc=nth,dc=ch dnpass = xxxxxxxxxx ldap_version = 3 base = dc=nth,dc=ch #deref = always scope = subtree user_attrs = mail=user user_filter = (|(&(objectclass=inetOrgPerson)(mail=%u))(|(mailAlternateAddress=%u))) pass_attrs = uid=user pass_filter = (&(objectclass=inetOrgPerson)(|(mail=%u)(mailAlternateAddress=%u))) default_pass_scheme = CRYPT Basicaly, I want to make check: if deliveryMode=nolocal > do not deliver to mail=some.mail(a)tld.com (only to mailForwardingAddress) else deliver normally :) Thnx, -- Zeljko Culek IT Department Samurai Digital d.o.o.

This is my /etc/dovecot/conf.d/dovecot-ldap.conf.ext hosts = xxx.xxx.xxx.xxx auth_bind = yes dn = cn=admin,dc=nth,dc=ch dnpass = xxxxxxxxxx ldap_version = 3 base = dc=nth,dc=ch #deref = always scope = subtree user_attrs = mail=user user_filter = (|(&(objectclass=inetOrgPerson)(mail=%u))(|(mailAlternateAddress=%u))) pass_attrs = uid=user pass_filter = (&(objectclass=inetOrgPerson)(|(mail=%u)(mailAlternateAddress=%u))) default_pass_scheme = CRYPT Basicaly, I want to make check: if deliveryMode=nolocal > do not deliver to mail=some.mail(a)tld.com (only to mailForwardingAddress) else deliver normally :) Thnx, Zeljko

[Dovecot] Index issue?
by IT geek 31 10 Dec '13

10 Dec '13

I've just hastily migrated from Dovecot 1.2.9 to 2.2.9 due to a disk crash. When I say hastily, I literally copied the user's mail data files to the new server and then started the Dovecot service. The trouble is, I now have a user who can see all the subfolders of her inbox in Outlook, but not on her iPad. Do I need to re-index her mail folders? The data is there (as seen by Outlook 2013) and is good, but the iPad mail client only sees the top-level folder. Any thoughts? -Mark

[Dovecot] Problem with INDEXes and deleting shared folders
by Achim Gottinger 10 Dec '13

10 Dec '13

Hi, I use dovecot 2.1.7 on debian wheezy. I have a bunch of shared folders whom i configured to store the indexe's under the users mail_location/shared/%%u. I configured acl's for those shared folders in an way that all users should be able to add and delete folders (for example "group=buchhaltung keilrwtsx"). Creating folders works fine but if i try to delete such an folder i get the following error. Dec 10 12:03:41 logon-zor dovecot: imap(ag): Debug: Can't rename 'shared/buchhaltung/Test' to 'Trash/Test': one namespace has index dir and another doesn't Of course there is no dovecot.index file in /home/vmail/buchhaltung/mai/.Test but there is one in /home/ag/vmail/mail/shared/buchhaltung/.Test and in /home/ag/vmail/mail/.Trash. Seems dovecot does not honour the shared namespaces index settings when trying to rename that folder. Is there an fix for this issue in 2.1.7 or would upgrade to 2.2.5 (from debian unstable) help? Thanks in advance Achim Gottinger Here are my namespace mail_location etc. settings: mail_home = /home/vmail/%u mail_location = maildir:/home/vmail/%u/mail:INDEX=/home/vmail/%u/mail:INBOX=/home/vmail/%u/mail/.INBOX mail_uid = 998 mail_gid = 998 first_valid_uid = 998 first_valid_gid = 998 mail_shared_explicit_inbox = yes maildir_very_dirty_syncs = yes namespace { list = children location = maildir:/home/vmail/%%u/mail:INDEX=/home/vmail/%u/mail/shared/%%u:INBOX=/home/vmail/%%u/mail/.INBOX prefix = shared/%%u/ separator = / subscriptions = no type = shared } namespace { inbox = yes location = maildir:/home/vmail/%u/mail:INDEX=/home/vmail/%u/mail:INBOX=/home/vmail/%u/mail/.INBOX prefix = separator = / type = private }

[Dovecot] Question regarding quotas (is this a bug or intended behavior) ?
by Gilles Chauvin 09 Dec '13

09 Dec '13

Hi, I was wondering if this is a normal behavior (test was made using Dovecot v2.2.9). In my config, quotas are configured as follows: plugin { quota = dict:Userquota::file:%h/dovecot-quota quota_rule = *:storage=1G quota_rule2 = Trash:ignore } # doveadm mailbox status -u my_user "messages vsize" '*' Trash messages=4997 vsize=229535631 Drafts messages=0 vsize=0 Sent messages=0 vsize=0 Junk messages=0 vsize=0 INBOX messages=0 vsize=0 # doveadm -f flow quota get -u my_user Quota name=Userquota Type=STORAGE Value=0 Limit=1048576 %=0 Quota name=Userquota Type=MESSAGE Value=0 Limit=- %=0 The 4997 mails in the Trash mailbox are ignored as desired, but now, if I have the following case: # doveadm mailbox status -u my_user "messages vsize" '*' Trash messages=0 vsize=0 Trash/TEST messages=4997 vsize=229535631 Drafts messages=0 vsize=0 Sent messages=0 vsize=0 Junk messages=0 vsize=0 INBOX messages=0 vsize=0 (As you can see mails were moved to a Trash/TEST mailbox) # doveadm -f flow quota get -u my_user Quota name=Userquota Type=STORAGE Value=220918 Limit=1048576 %=21 Quota name=Userquota Type=MESSAGE Value=4997 Limit=- %=0 I tried to add the following quota_rule: quota_rule3 = Trash/*:ignore But this doesn't fix anything. Do you have any idea about why this is not working ? Thanks, Regards, Gilles.

[Dovecot] Use Replication plugin to do a backup (one-direction sync)
by Francesco Barresi 09 Dec '13

09 Dec '13

Hello, I have a setup where I need to have Server A (dovecot 2.1.7) replicated on a Server B (dovecot 2.1.7). I know that I can do a per user backup with: doveadm -D backup -u %u remote:mailmirror@serverB I would like to use Notify/Replication to backup only when there's something new. I don't understad if the Replication plugin can be used to do a backup server, or it's only of for two-way sync? My question is: It's possible to use Replication to do a backup (one-direction sync)? Thanks Francesco

[Dovecot] Expire plugin - empty expires table

Hello, Dovecot does not fill expires table when moving messages to Trash or Junk folder.

[Dovecot] [PATCH] lib-sql/driver-mysql.c - Add support for enabling MYSQL_OPT_SSL_VERIFY_SERVER_CERT
by Gareth Palmer 08 Dec '13

08 Dec '13

Hello, The following patch adds support for enabling MYSQL_OPT_SSL_VERIFY_SERVER_CERT. It makes the mysql client library check that the commonName in the server's SSL certificate matches the host name provided to mysql_real_connect() and aborts the connection if the name doesn't match. An example connect string would look something like: connect = ... ssl-ca=/path/to/ca.cert ssl-verify-server-cert=yes By default the mysql client library does not perform this check.

[Dovecot] dovecot.index-Errors with multiple IMAP client access in Dovecot 2.2
by Martin Rabl 08 Dec '13

08 Dec '13

Hello list, I hope you can help me! My self-compiled dovecot 2.2.6 (and the two minor versions before, too) throws that errors: Nov 28 18:29:00 mailserv dovecot: imap(martin(a)example.com): Error: Transaction log /srv/vmail/example.com/martin/Maildir/dovecot.index.log: duplicate transaction log sequence (25) Nov 28 18:29:00 mailserv dovecot: imap(martin(a)example.com): Error: /srv/vmail/example.com/martin/Maildir/dovecot.index log position went backwards (24,40 < 25,10028) ... and so on ... duplicate transaction log sequences and backwards gone log positions, and this always, when I use at least two IMAP clients at the same time (better: the two clients are online and logged in at the same time). That happens only with one user (me ;-) ), the other about 15 users on this server are having no problems. What I see: the clients are bothering each other, but I don't know, why. I thought about the used reiserfs filesystem on the server, but there were no problems with 1.2 on the same server. Some words about my client setup: I use Thunderbird and iPhone at the same time, and as a third client on the same Server there is a Thunderbird instance at my company, which runs parallel to the other two. Seems to be weired, but isn't really (IMHO ;-) ). Sometimes there are two TBs at the same mailbox, sometimes only the iPhone and a TB, sometimes all three. This runs quite good for long time with dovecot 1.2 and 2.1.x (the last one at my company in a similary setup with more users and several clients at the same time).

[Dovecot] shared folder - ACL
by Héctor Moreno Blanco 08 Dec '13

08 Dec '13

Hello everyone, I've trying to configure shared folders in dovecot 2.1.6 without success. My configuration is: mail_plugins = quota autocreate mail_log notify acl ... plugin { ... acl_shared_dict = file:/etc/dovecot/shared-mailboxes.db ... } Protocol imap { ... mail_plugins = imap_quota imap_acl ... } When I try to set acl to a folder: a02 setacl inbox.test1 user1 lr a02 BAD Error in IMAP command SETACL: ACLs disabled. In the logs, I can see: dovecot: imap(testing_ddfr): Debug: acl: No acl setting - ACLs are disabled What am I missing? Thank you very much in advanced. Kind regards. Héctor Moreno Blanco.

[Dovecot] imap list response has an extra field on some mailboxes.
by Kui Zhang 08 Dec '13

08 Dec '13

Hello, per rfc3501 7.2.2. LIST Response Contents: name attributes hierarchy delimiter name Dovecot: 2.1.16 /usr/lib/dovecot/imap -u user(a)domain.tld list "" "*" Most responses are correct. But some appears to not be. """ * LIST (\HasNoChildren) "/" {117} path/to/"part_mailbox_name" other_parts * LIST (\HasNoChildren) "/" {10} "test" box """ char after {117} appears to be \n. All affected mailboxes appears to have ' " ' in mailbox name. And the number between '{' '}' appears to be the length of the path. Anyone ran into this issues before? If so, how to fix it? Is it a bug? Other rfc I should read? Thanks Kui.Z

[Dovecot] Dovecot readable compressed mail archive
by Dave Hall 08 Dec '13

08 Dec '13

Hello. Is Dovecot able to create and/or read any sort of compressed mail archive? We have a large installation with a few users who need to keep a large amount of email available. With maildir this means a large number of individual files, leading to additional load on our backup process. Even using a compressed mbox file as an archive would help, but only if Dovecot is able to interact with this file seamlessly while keeping current email in the maildir format. Please pardon if this is old business, but I haven't been able to find any reference to it by searching. Thanks. -Dave -- Dave Hall System Administrator Computer Science Binghamton University davehall(a)cs.binghamton.edu 607-760-2328 (Cell) 607-777-4641 (Office)

Re: [Dovecot] zlib config questions
by Richard Platel 08 Dec '13

08 Dec '13

You only need to add the zlib plugin to mail_plugins once. As far as I know, there's no indication in the logs that mail is being compressed, and the filename isn't modified to indicate that it's compressed, but, of course, the files are zlib data on disk. One gotcha if you're using maildir is, if you're planning to compress old mail, make sure that the S= and W= sizes in the filenames are correct, otherwise dovecot errors and closes the client session, and it can't repair the filename on it's own.

[Dovecot] delete message with specified id
by Костырев Александр Алексеевич 08 Dec '13

08 Dec '13

Good day, everyone! Could someone help me to find a way to delete message with certain id from all users's mailboxes? What seems to be a problem: I have configured exim + dovecot lmtp I got a long list of aliases in BD in form of: +----------+-------------------------------------+ |alias_name recipients | (for example) -----------|-------------------------------------+ | list_a | user1@example.org,user2@example.org | +----------|-------------------------------------+ When I send a message to that list_a, user1 and user2 get the mail and I see this in log: Dec 6 12:12:27 beta-mail dovecot: lmtp(16419, user1(a)example.org) copy from INBOX: box=INBOX, uid=1, msgid=<E1VojxY-0004Gl-Gu@beta-mail>, size=570 Dec 6 12:12:27 beta-mail dovecot: lmtp(16419, user1(a)example.org) oCOXKmAkoVIjQAAA635u4w: msgid=<E1VojxY-0004Gl-Gu@beta-mail>: from=root@beta-mail: subj=: saved mail to INBOX Dec 6 12:12:27 beta-mail dovecot: lmtp(16419, user2(a)example.org) copy from INBOX: box=INBOX, uid=1, msgid=<E1VojxY-0004Gl-Gu@beta-mail>, size=570 Dec 6 12:12:27 beta-mail dovecot: lmtp(16419, user2(a)example.org) oCOXKmAkoVIjQAAA635u4w: msgid=<E1VojxY-0004Gl-Gu@beta-mail>: from=root@beta-mail: subj=: saved mail to INBOX Is it possible to delete these letters with known msgid=<E1VojxY-0004Gl-Gu@beta-mail> from all users mailboxes with couple of simple commands ? How do I do it currently: in exim's log I get mailaddress of a user, get into his mailbox (wich cd), find the letter I need, with ls -i I get inode, search (with find) through all users mails and delete all files with that inode, then I have to rebuild dovecot indexes with doveadm mailbox status -A -t all INBOX -- С уважением, Костырев Александр администратор Linux-систем

[Dovecot] pigeonhole openssl s_client
by LEVAI Daniel 08 Dec '13

08 Dec '13

Hi! I'm trying to get information about a server certificate from a pigeonhole sieve server. Various connection attempts show only "wrong version number" or "unknown protocol" errors from openssl: $ openssl s_client -connect example.com:4190 { -tls1, -tls1_1, -tls1_2 } [ -starttls { imap, pop3 } ] None of these work. I'm trying to see who signed the server cert. How could I do this? Thanks, Daniel -- LÉVAI Dániel PGP key ID = 0x83B63A8F Key fingerprint = DBEC C66B A47A DFA2 792D 650C C69B BE4C 83B6 3A8F

[Dovecot] Replication via sneakernet
by David Bishop 07 Dec '13

07 Dec '13

Is there a way to get a running transaction log from a Dovecot instance to synchronize (and I use that word very, very loosely) multiple instances that don't share a network? Why I would want to do such a thing: I have a couple way stations along a long, winding road through very hilly country, and at each of these stations, I have a few people (and many, many more at one end of the road). Which people are where varies from hour to hour (but they're all members of a known, larger, group of people with accounts). It would be helpful to get communication (however limited) along this road (and establishing direct communication, either through radio or landline, is not feasible within the budget constraints I have), and it is possible to store a complete copy of the mail spool to a small box at each station (the total mail spool over the period I care about is in the tens of megs). There are trams shuttling back and forth along this road (stopping at each station), and adding a small box (such as a weatherproofed Raspberry Pi with a wifi dongle) to transport files up and down the road is pretty simple. Doing incremental copies of the mail spool is also simple, keeping track of files that get moved or deleted is a bit harder (but still not that bad), but I have no idea how hard it is to track what messages have been seen, especially for the shared folders (which we use instead of mailing lists). I realize this is not a "normal" use of Dovecot, but given this, does anyone who knows the software (and how it keeps track of messages) better have suggestions on how to approach the problem?

[Dovecot] Easy migration from Dovecot 1.2.16 ppc maildir to 2.1.17 amd64 mdbox
by Philippe Lelédy 07 Dec '13

07 Dec '13

Hi After http://retrospekt.dk/2011/08/migrating-maildir-to-dovecot-2-0-dbox/ I used a two phases process. The first, transfering over the network, is done by this shell function, on the *new* server. The argument is the <user> fetchOldServer () { rsync -poazuHK --exclude="**/dovecot.index*" \ -e ssh root@oldServer:/var/mail/Maildirs/$1 /var/mail/oldServer/ } I had to add --exclude="**/dovecot.index*" because of a change of endianness (ppc -> amd64). the second, having dovecot import the folder, is done by this second fonction dsync () { doveadm backup -R -u $1(a)mondomaine.fr maildir:/var/mail/oldServer/$1 } this one is really fast. Both in one function doveImport() { fetchOldServer $1 && dsync $1 } I tried for initial load to empty mailbox. I am not sure it will works on a non empty mailbox. But would be nice, as it would allow a fast last minute sync before switch, minimizing downtime. Ph. Le

Re: [Dovecot] Dovecot readable compressed mail archive
by Dave Hall 06 Dec '13

06 Dec '13

Alan, My goal is to reduce the file count in my backups. Based on the information at the link you sent it looks like for a Maildir setup the file count remains the same. Do you know if it's possible to have a mixed config with Dovecot where for a given user the Inbox is a maildir, but the archives are compressed mbox files? Thanks. -Dave On 12/04/2013 02:06 PM, Alan McGinlay wrote: > http://wiki2.dovecot.org/Plugins/Zlib try this.. Excuse the lack of quoted text, im on my phone

[Dovecot] Authentification Dovecot + Samba4
by dago＠quantentunnel.de 06 Dec '13

06 Dec '13

Hello list, I am struggling with setting up dovecot 2.1.7 with samba 4.1.2 on debian wheezy. Dovecot should authenticate via LDAP, but I cannot get it to work reliably. Sometimes auth works, sometimes not. Referals are already activated in ldap.conf … LDAP-authentication works fine with other clients (Apache Directory Studio, …) Has somebody got a similar setup running? I would love some hints on how to debug this issue … Thank you!

[Dovecot] SQL as a storage backend
by Zachary Sturgeon 06 Dec '13

06 Dec '13

Hello, I am researching using dovecot with an SQL database as the storage backend. From what I've read, dovecot only supports mbox style file storage, but I'd like to investigate the possibility of using a database instead. According to http://dovecot.org/pipermail/dovecot/2006-June/013818.html, this possibility has been explored before and has generally been accepted that Dovecot is not optimized to handle this. Any suggestions? - Zachary Sturgeon

[Dovecot] UIDL and namespaces after qmail-pop3d and BincIMAP
by Adrian C. 06 Dec '13

06 Dec '13

Hello, I migrated qmail-pop3d and BincIMAP to Dovecot in the past, and I could always tweak the settings a little to match what old services used to provide, namely namespaces (separator /, prefix INBOX/) and pop3_uidl_format (%f). This time I'm migrating to a large mail system which has its configuration set differently and there's no changing it. pop3_uidl_format = %08Xu%08Xv namespace private {prefix = INBOX. separator = . inbox = yes} Am I corrent in thinking dsync plugin is the only chance I have of getting this mail migrated right? Unfortunately Debian's Dovecot is much much older than required v2.1.4... so I could use some advice from Dovecot experts. Thanks. -- Adrian C.

[Dovecot] Design details of high performance dovecot cluster
by JEHERUL 06 Dec '13

06 Dec '13

Dear All, Currently we are running a mail system for 10000 users each 2GB mailbox. At present we have 5 mail servers where users mailboxes are distributed almost uniformly. We have a HP SAN Storage (HP EVA 6400) where mailboxes are stored. We partition the storage into five vg and each is mounted on the 5 servers. We are using postfix and dovecot. The system was running fine but currently we notices high IO load due to IMAP connection. So we are planning to build a dovecot cluster. Please suggest some design for the dovecot cluster keeping in mind to our scenario. (If needed we can buy additional hardware like load balancer). With Thanks and Regards -- Jeherul Islam India

[Dovecot] Active Directory LDAP userdb and dovecot
by Simone Ferretti 06 Dec '13

06 Dec '13

Hello everybody, I have a problem with LDAP userdb and dovecot. Let me first explain my LDAP configuration: I got three Active Directory LDAP servers (a.galliera.it, b.galliera.it, c.galliera.it) responding round robin to the name galliera.it. I want to use LDAP for the userdb lookup, so I configured dovecot-ldap-userdb.conf.ext as follow: hosts = galliera.it # round robin base = dc=galliera,dc=it ldap_version = 3 auth_bind=yes auth_bind_userdn = %n(a)galliera.it dn=CN=stampa,CN=Users,DC=galliera,DC=it dnpass=stampa base = DC=galliera,DC=it scope = subtree deref = always user_attrs = sAMAccountName=home=/home/dovecot.galliera.it/%$,=uid=8,=gid=8 user_filter = (&(objectClass=person)(sAMAccountName=%n)) default_pass_scheme=CRYPT With this configuration everything go fine, I can authenticate and lookup my users in the expected way. What follows is the conversation between (one of) the LDAP server(s) and dovecot after a issue of the command $ doveadm user -u <user>@galliera.it : 62.785686 10.0.31.235 -> 10.0.5.0 TCP 74 43053 > ldap [SYN] Seq=0 Win=14600 Len=0 MSS=1460 SACK_PERM=1 TSval=536265719 TSecr=0 WS=32 62.786216 10.0.5.0 -> 10.0.31.235 TCP 78 ldap > 43053 [SYN, ACK] Seq=0 Ack=1 Win=16384 Len=0 MSS=1460 WS=1 TSval=0 TSecr=0 SACK_PERM=1 62.786279 10.0.31.235 -> 10.0.5.0 TCP 66 43053 > ldap [ACK] Seq=1 Ack=1 Win=14624 Len=0 TSval=536265719 TSecr=0 62.786394 10.0.31.235 -> 10.0.5.0 LDAP 122 bindRequest(1) "CN=stampa,CN=Users,DC=galliera,DC=it" simple 62.786583 10.0.31.235 -> 10.0.5.0 TCP 74 43054 > ldap [SYN] Seq=0 Win=14600 Len=0 MSS=1460 SACK_PERM=1 TSval=536265719 TSecr=0 WS=32 62.786953 10.0.5.0 -> 10.0.31.235 TCP 78 ldap > 43054 [SYN, ACK] Seq=0 Ack=1 Win=16384 Len=0 MSS=1460 WS=1 TSval=0 TSecr=0 SACK_PERM=1 62.787008 10.0.31.235 -> 10.0.5.0 TCP 66 43054 > ldap [ACK] Seq=1 Ack=1 Win=14624 Len=0 TSval=536265719 TSecr=0 62.787039 10.0.31.235 -> 10.0.5.0 LDAP 122 bindRequest(1) "CN=stampa,CN=Users,DC=galliera,DC=it" simple 62.788484 10.0.5.0 -> 10.0.31.235 LDAP 88 bindResponse(1) success 62.788528 10.0.31.235 -> 10.0.5.0 TCP 66 43053 > ldap [ACK] Seq=57 Ack=23 Win=14624 Len=0 TSval=536265719 TSecr=36040952 62.789334 10.0.5.0 -> 10.0.31.235 LDAP 88 bindResponse(1) success 62.789365 10.0.31.235 -> 10.0.5.0 TCP 66 43054 > ldap [ACK] Seq=57 Ack=23 Win=14624 Len=0 TSval=536265720 TSecr=36040952 62.789462 10.0.31.235 -> 10.0.5.0 LDAP 174 searchRequest(2) "DC=galliera,DC=it" wholeSubtree 62.790396 10.0.5.0 -> 10.0.31.235 LDAP 392 searchResEntry(2) "CN=Marco De benedetto,OU=S.S.C.

[Dovecot] zlib config questions
by Terry Barnum 05 Dec '13

05 Dec '13

After nearly running out of space I swapped in larger disks and then saw the recent threads about zlib compression. Unfortunately I'm still confused after reading <http://wiki2.dovecot.org/Plugins/Zlib>. In order to compress new email being stored do I only need to change 10-mail.conf to this: mail_plugins = $mail_plugins zlib and 90-plugin.conf to this: plugin { zlib_save_level = 6 zlib_save = gz ... Or do I need to instead (or also?) add it to the list of plugins in 20-imap.conf? A simple 'sudo doveadm reload' to enable? Once enabled, is there an indication in the logs that compression is taking place? Do new mail files have a suffix like .Z to indicate they've been compressed? Any gotchas to be aware of? I'm running macports dovecot 2.2.5. Thanks for any help. -Terry Terry Barnum digital OutPost http://www.dop.com

[Dovecot] Syslog debug messages
by Bruno Galindro da Costa 05 Dec '13

05 Dec '13

Is there a way to configure dovecot to register in syslog the debug messages enabled by mail_debug=yes as a debug not as information? I need this because I want to send this kind of information only to a remote server. I've configured rsyslog to do this, but dovecot is registering those debug messages as information not as debug (as I expected). This is my rsyslog config: mail.info;\ mail.warning;\ mail.err;\ mail.crit -/var/log/mail.log mail.* :omrelp:192.168.2.162:2514 root@imap:~# dovecot -n # 1.2.9: /etc/dovecot/dovecot.conf Warning: fd limit 1024 is lower than what Dovecot can use under full load (more than 4748).

[Dovecot] FTS solr issue with second private namespace
by Andreas Oster 05 Dec '13

05 Dec '13

Hi all, I have just stumbled over an issue with the FTS plugin of dovecot. For our primary namespace, INBOX and its subfolders, searching works without any problems but in a second namespace, which I have created for old/archived mails, searching of the mail text/body does not work. I can see the search request in the tomcat log but no result is created and the mail client (Thunderbird) keeps displaying the serach message without returning any results. Tomcat6 catalina.out: Dez 02, 2013 11:58:00 AM org.apache.solr.core.SolrCore execute INFO: [] webapp=/solr path=/select params={fl=uid,score&sort=uid+asc&q=body:"schiller"&fq=%2Bbox:1b4de60d0a6287522d0c00004424cda4+%2Buser:"testuser"&rows=2} hits=0 status=0 QTime=1 I am currently using Dovecot 2.2.9 and do not have any special FTS config: mail_plugins = quota mailbox_alias fts fts_solr plugin { fts = solr fts_solr = break-imap-search url=http://localhost:8080/solr/ fts_autoindex = yes } Thank you for your kind help best regards Andreas

[Dovecot] Full text search improvements
by Timo Sirainen 05 Dec '13

05 Dec '13

FTS indexing is something I hear quite often nowadays. I’ve added some hacks to make it work better for some installations, but it’s about time to think about the whole design and how it could be improved for everyone in future. Here are some of my initial thoughts. Currently Dovecot supports 3 full text search engines: Solr, CLucene and Dovecot Squat. CLucene plugin has various features built in, which should have been built in a generic way to work with all the engines (although Solr has most of those already built-in). Squat was abandoned a few years ago in favor of Solr/CLucene, but perhaps it could be brought back to life, since it looks like its index sizes could be smaller than Lucene's. Here's a list of things that should be added to generic Dovecot FTS code to improve all the backends: 1. Support for multiple languages. Use textcat while indexing to guess the language of the indexed data. (Perhaps run it separately for each paragraph to handle multi-language mails? Or at least many emails begin/end with different language than the text in the middle, e.g. "Foo Bar wrote:" is often in various languages.) Index the data using the detected language's stemming and other features. Keep track of which languages have been used in the index, and when searching stem the search words to all the used languages. Since each added language requires additional searches and there's the possibility of wrong detection, the list of allowed languages could be configurable. See also http://ntextcat.codeplex.com/ or at least change textcat to use UTF8. 2. Word stemming. This can be done for many languages with Snowball library. Solr has also implemented several other languages, perhaps its code can be somehow automatically translated to C(++) for use with Dovecot? 3. Don't index language-specific stopwords. We can get the word lists from e.g. Solr. 4. Try to detect compound words and index each part separately for languages that use them. http://wiki.apache.org/solr/LanguageAnalysis#Decompounding suggests two possible ways to do it. 5. Normalize words (e.g. drop diacritics). libicu can be used for this. 6. Drop (Unicode) characters that don't belong to the language? Or especially don't index most of the weird Unicode characters. This would avoid filling the index with unnecessary garbage. 7. Don't index non-text data? For example if there is large block of base64 data or something else that definitely doesn't look like text, it's pretty useless to index it. Then again, we do want to index all kinds of IDs that someone might want to search. This could be a bit difficult to implement well. 8. Index attachments separately, so it would be possible to search only attachments. (Should "SEARCH BODY word1 BODY word2" return matches if word1 and word2 are in different attachments?) 9. Attachments can be translated to indexable UTF-8 text already with fts_decoder setting by doing it via a conversion script. This could also support Apache Tika server directly. 10. It should be configurable which fields are indexed. Body and header would always be separately indexed. Optionally there could be also at least: attachments, From, To, Cc, Bcc and Subject. The From/To/Cc/Bcc could also be indexed together in one "addresses" field. The more fields there are, the larger the index, but better/faster search results. 11. Each indexed mail should have metadata: Mailbox GUID, mail UID and the language the mail was indexed with. For attachments there should also be the MIME part number. When matching results, drop results if returned language doesn't match the query language. Squat ----- Currently Squat index consists of a trie containing all the words and pointer to a file listing all the message UIDs that contain them. Each node in the trie has a pointer to the UIDs, so e.g. with "abc" the "a" node will contain UIDs of all mails that contain the "a" letter (e.g. 1,3-5,10). "ab" node will contain mails that have the "ab" substring. Since the "ab" is a subset of "a", the "ab" won't contain UIDs directly but instead it contains indexes to the "a" list to get a better compression (e.g. UID 3-5,10 -> 2-4 indexes in the "1,3-5,10" list). The "abc" node then similarly refers to the "ab" node's indexes. It's configurable how long words Squat will index. Also substring matching is configurable. By default both are 4 letters, so words longer than 4 letters will be split to 4 letter pieces which are indexed (e.g. "dovecot" -> "dove", "ovec", "veco", "ecot"). When searching these pieces are looked up and the results are merged. It's pretty pointless to do a search for 1-2 letter substrings. Most likely the user wants to find 1-2 letter word instead. Perhaps this is true also for 3 letters? The Squat index could be changed to only add results for the first 1-2 (or 1-3?) letters only for full words, not to word prefixes. This of course would mean that the "ab" referring to "a" UID list would no longer work for the first nodes. Substring searching likely wouldn't work very nicely for stemmed words. So Squat should probably index the full stemmed word and then also index the unstemmed word in the small 4 letter pieces. It should be possible to also disable substring searching entirely. Squat already attempts to reduce disk space by encoding the common characters with less bits than other characters. This is hardcoded for English language though. Each index compression could analyze the most common letters and dynamically use those. Perhaps different languages could even use separate Squat index files to get the most advantage of this? Although if there are a lot of languages it's a bit annoying to have many different index files. Squat currently indexes each Unicode character as one letter, so there can be quite a huge number of different 4 letter words. This substring indexing should probably be disabled for words that contain letters not used by the current language. The UID lists are not compressed very efficiently. See http://www2009.eprints.org/41/1/p401.pdf for alternatives. There is currently one Squat index per mailbox. There should be one per user. This requires adding a separate ID -> { mailbox GUID, UID, language, mime part } mapping file. Squat indexes should be updated in two parts. For old mails there are the large trie+uidlist base files in optimized format. For new mails there are small trie+uidlist files in a format where they are just appended to. When the trie or uidlist becomes large enough, it's first internally sorted/optimized, and then merged with the base files by recreating new optimized base files. This fixes the scalability problem with current large Squat indexes where with large unsorted indexes the sorting could have taken forever. Since substring searches in Squat produce only "maybe matches" UID lists, the mails still need to be opened and searched through. This step could probably also do the same language detection + stemming as is done during indexing to improve the search results. (And this feature could be enabled even if no FTS index is enabled.)

[Dovecot] Ubuntu packages and broken link in docs
by Alan McGinlay - SICS 04 Dec '13

04 Dec '13

Hi, Two things: 1. Does anyone know of a good PPA with updated packages of Dovecot for Ubuntu? "For the latest Dovecot for latest Ubuntu LTS see Xiaoka APT Repository. (Outdated. Could someone provide a ppa for latest stable Dovecot, please?)" 2. On the http://wiki2.dovecot.org/PrebuiltBinaries#Ubuntu page there is a link to a supposedly outdated PPA, the ppa page now redirects to an ad for the guys services so should probably be removed. /Alan

[Dovecot] Different settings for SSL/non-SSL protocols
by Алексей Прокопчук 04 Dec '13

04 Dec '13

Good time of the day! It is possible to setup dovecot with different requirements for SSL and non-SSL protocols? What would I like to do: pop3/imap non-SSL = allowed plain text authentication. pop3/imap with SSL = allowed plain text authentication with required valid SSL certificates. I need to allow access from any IP address for first group of users, which have valid SSL certificates. And allow access from only local IP addresses for second group of users which doesn't have SSL certificates at all. I tried to setup dovecot for such task. SSL and non-SSL pop3/imap works together fine, but without require valid SSL certificates. If I set auth_ssl_require_client_cert = yes, non-SSL pop3/imap refuses authentication without valid SSL certificate. I tried to use different sections for protocol pop3 {} and protocol pop3s {} (and imap/imaps) but this seems doesn't work. Is there any way to solve this? Thanks for attention, with best regards, Alexey Prokopchuk (AP8686-RIPE)

[Dovecot] Complete migration from Cyrus on remote server
by Alan McGinlay - SICS 04 Dec '13

04 Dec '13

Hi All! I am working on a complete migration from an old solaris machine running Cyrus IMAP v2.3.14 and wish to migrate all users to a new ubuntu vm running Dovecot 2.0.19. What I have so far is a fully functional dovecot installation with LDAP / Dovecot SASL auth using Maildir++. My plan is to use Perdition IMAP proxy on a third host and migrate users a few at a time (see attached picture of my whiteboard). The proxy is in place and already used by webmail clients to connect to the old server, shortly I will change the dns to point smtp.domain.com and imap.domain.com etc to the proxy instead of the old server but I haven't finished testing yet. Once that is done it is a simple matter of changing the proxy configuration per user to make them hit the new server instead. The problem I am having with this is that I am using Imapsync (http://imapsync.lamiral.info) to perform the initial synchronization (i have scripted it to maintain sync every 10 minutes with the addtion of "--maxage 1" option) using the following command line options: /usr/local/bin/imapsync --noreleasecheck --useheader ALL --delete2 --expunge2 --tmpdir /var/vmail/cache --subscribe --subscribed --tls1 --tls2 --usecache --nofoldersizes --nocheckmessageexists --host1 oldserver.domain.com --authuser1 adminuser --user1 testuser(a)domain.com --authmech1 PLAIN --password1 <HIDDEN> --host2 newserver.domain.com --authuser2 adminuser --user2 testuser(a)domain.com --authmech2 PLAIN --password2 <HIDDEN> All email is copied over and stored in dovecot as you would expect. Then I switch the user to the new server on the imapproxy and restart the client (thunderbird or whatever). This is where all email headers are downloaded again as if they were new! There are *Many* users here who would complain intensely if this happened and I was really wanting the migration to be as invisible as possible. Is there a way to do what I have described without the clients redownloading headers / full messages? I have been working on this for some time now but have hit a roadblock and don't know where to turn, any help would be really appreciated! Notes: * The proxy is not used during imapsync. * Some users have 20 years worth of mail running into 10's of GB * I have looked at dsync but the docs state that the mailbox should not be accessed during sync, this is not possible for me (it doesn't say why this is the case however)

[Dovecot] Possible managesieve bug.
by Pedro R. Benito da Rocha 04 Dec '13

04 Dec '13

Hi, I'm migrating from from 1.1 to 2.2. Currently I am doing test to ensure I'm doing it right. On the old server the managesieve config says: sieve = /correo/%d/%u/dovecot.sieve sieve_dir = /correo/%d/%u/Sieve and is working fine. But the same config on the new server is not working. I have activated verbose logging and this is the result: Dec 3 09:59:41 imap-01 dovecot: managesieve-login: Login: user=<xxxx(a)ubu.es>, method=LOGIN, rip=10.145.4.65, lip=10.145.4.45, mpid=29855, session=<T7hfhJ3s+QAKkQRB> Dec 3 09:59:41 imap-01 dovecot: managesieve(xxxx(a)ubu.es): Error: sieve-storage: Performing readlink() on active sieve symlink '/correo/ubu.es/xxxx(a)ubu.es/dovecot.sieve' failed: Permission denied Dec 3 09:59:41 imap-01 dovecot: managesieve(xxxx(a)ubu.es): Error: sieve-storage: Failed to stat active sieve script symlink (/correo/ubu.es/xxxx(a)ubu.es/dovecot.sieve) Permission denied.

I modified the permissions using 0777 but the error message is the same. I have made other tests to see if I can find the problem, and I made it work if I delete "%d" from config, this way: sieve = /correo/%u/dovecot.sieve sieve_dir = /correo/%u/Sieve I have copied all filters preserving permissions, and with the same file permissions is working. If I add the '%d' to the path error comes again. Can anyone tell me if this is the normal behavior or is a bug?

[Dovecot] Gettings mails recently moved to a folder
by Florian Lindner 03 Dec '13

03 Dec '13

Hello, some spam training tools learn the same message over and over again. Since I want to use a daily cronjob to train messages and I do not want to have the same messages trained multiple times, I need to way to get new messages in a folder. Is there a (consolish) way to get a list of messages that were recently moved to a folder? dovecot does not modify mtime, according to RFC 3501. Thanks, Florian

[Dovecot] imap-login hangs after receiving revoked SSL certificate
by Алексей Прокопчук 03 Dec '13

03 Dec '13

Good time of the day! My English is not very good, excuse me if I said something wrong. I use dovecot-2.1.16 on Gentoo Linux amd64. I need to setup dovecot (imap and pop3) for SSL and non-SSL connection simultaneously. For SSL connections client must submit a valid SSL certificate. Now SSL part of dovecot.conf looks like this: ----------------- ssl = yes ssl_cert = </etc/ssl/dovecot/dovecot.pem ssl_key = </etc/ssl/dovecot/dovecot.pem ssl_ca = </etc/ssl/ca/ca.pem ssl_verify_client_cert = yes auth_ssl_require_client_cert = yes protocol !smtp { auth_ssl_require_client_cert = yes } ----------------- All works fine with valid certificates. But if I submit revoked certificate, dovecot doesn't send error or success messages to mail client, process 'imap-login' eats 100% CPU and completely hangs. Only SIGKILL can terminate it. When dovecot receives revoked certificate, following messages appears in the log: ------------------ Dec 2 13:50:26 mail dovecot: imap-login: Invalid certificate: certificate revoked: /O=AP inc./OU=Admins/CN=Alexey Prokopchuk/UID=alexpro Dec 2 13:50:26 mail dovecot: imap-login: Invalid certificate: Different CRL scope: /CN=AP inc. root certification authority/O=AP inc./C=UA Dec 2 13:50:39 mail last message repeated 17950 times ------------------- If I'm not mistaken, in case of revoked certificate submission, dovecot must simply answer "SSL error" or "permission denied" to client and close connection, but according to log, it tries to check certificate again and again and do it in infinite loop. I can't understand for now - I misconfigured something or it's a bug? Thanks for attention, with best regards, Alexey Prokopchuk (AP8686-RIPE)

[Dovecot] proxy, userdb and passdb
by Jogi Hofmüller 03 Dec '13

03 Dec '13

Dear all, We are getting closer to the migration of our mailsystem. Now I have a special question. We are successfully using passdb { driver = pam } and that is good. Now, how would I tell dovecot to proxy certain users (the ones not yet migrated) to the old server? My attempts to configure an additional userdb failed since this seems to override the passdb setting. Grateful for any hints!

[Dovecot] Dove LDA vs Exim LDA
by Kumar Shantanu 02 Dec '13

02 Dec '13

Hello All, I have built up my email server with exim + dovecot + clamv/spamassasin. I am using exim as LDA(local delivery agent). I was reading about using dovecot as LDA but I couldn't find why should I use it? Now, I am looking expert advice on "Why should I use dovecot LDA" ? Is there any benefit in terms of functionality or performance ? Any advice/suggestion/feedbacks welcome. Thanks Shantanu

[Dovecot] doveadm table formatter: hidden titles may cause misaligned headers
by Julian Reich 02 Dec '13

02 Dec '13

Hello, I recently noticed a small bug in the doveadm table formatter: hidden titles may cause the headers to be misaligned. The behavior in question was introduced by commit <http://hg.dovecot.org/dovecot-2.2/rev/210282ae46e1> and doveadm -f table quota get -A may be used to reproduce it. Most simple patch attached: it simply restores the old behavior, to some extent. Actually hiding those titles may be desired. Regards, Julian Reich

[Dovecot] dovecot-antispam plugin problem with multiple messages
by Richard Platel 29 Nov '13

29 Nov '13

Hi With dovecot 2.2.5, and dovecot-antispam built from a recent HEAD pull, when copying multiple messages to or from a Spam folder, the plugin sends multiple copies of the first message to the backend. I've tried this with the pipe and spool2dir backends. For example with the spool2dir backend, via IMAP doing A COPY 1:3 Spam yields 3 copies of message id 1 in the dir: dev:imap-8.1 rplatel@imap01:/var/run/dovecot_as_tmp$ sudo -u mail md5sum * 28ad0a215eb7ecbd3a814a8a334d85bf 00000000001385586164-rplatel(a)ff-dev.com-00001s 28ad0a215eb7ecbd3a814a8a334d85bf 00000000001385586164-rplatel(a)ff-dev.com-00002s 28ad0a215eb7ecbd3a814a8a334d85bf 00000000001385586164-rplatel(a)ff-dev.com-00003s I see the same behaviour with the pipe backend, the pipe program is invoked 3 times, but with the same message content.

[Dovecot] proxy_maybe & director incompatibility
by Trent Lloyd 29 Nov '13

29 Nov '13

Hi Folks, I spent quite some time yesterday understanding how proxy works along with the director. I came to the conclusion that proxy_maybe and director cannot be used together, but this isn’t a true incompatibility so much as caused by the way things are handled and the order they are processed in. The way proxy_maybe works is that it is processed by the auth provider once it gets the response from the passdb, it checks for proxy_maybe and then checks for the ‘host’ parameter and compares it to the local IP (this is always null at that stage, because director won’t add host until later). proxy_maybe is deleted and then if the IPs do not match (i.e. the connection should be proxied) it sets proxy. This result is returned from the auth provider and then piped into director, which adds the relevant ‘host’ parameter if ‘proxy’ is set. The problem here is that because proxy_maybe is processed before director, it is not possible to conditionally proxy when using director — only if host is also returned from passdb. The secondary problem is that director only adds host= if proxy is set (and the auth code generally assumes proxy/proxy_maybe/proxy_always are exclusive settings) — this logic would also need to change. You would also need some logic to add host only if host doesn’t already exist, to handle situations where proxies might come from both passdb and/or director. I am seeking to understand if there is any significant reason proxy_maybe is handled during the auth section, it would seem better to simply always set ‘proxy=yes’, and then optionally have proxy_maybe passed all the way through to the connection stage and then do the local host check there. This would solve my use case, and I cannot imagine what else it would break — but I am no expert on dovecot or other people’s use cases, so I am hoping for feedback from others on this and what else would need to be considered or why this would not work before I spent time trying to implement the change. Thanks, Trent Lloyd w: www.webinabox.net.au

[Dovecot] Dovecot's brittle configuration syntax

Hi there, Whilst trying to come up with a minimal configuration for Dovecot: http://dabase.com/blog/Minimal_Dovecot/ I noticed the configuration syntax is a bit admin unfriendly. It's easy to get an infamous Error code 89. Is there any back story to the grammar or language this configuration is in? Kind regards,

It's conceivable to have all the default values work for you and only specify those that differ from defaults (or configure your system to conform to defaults if you want to place the proverbial cart before the horse), but that doesn't make it less complex -- it just hides it. (See doveconf -a if you want to see what you're shorthanding). If you want minimal configuration fuss, you can try uw-imapd. Not a lot of knobs to twist on that thing, but you'll have to accept all its limitations as well. A well chosen set of defaults that works for most people is a good design decision, but I've seen plenty of different and oddball layouts (including the sneakernet post preceding this one) that requires a lot of flexibility, which necessarily requires a lot of configuration to express them. The sample configuration is verbose because it doubles as documentation: you can use it as a starting point and remove the parts you don't need, or start from the documentation and move forward. I agree, though, that the documentation needs an editorial overhaul -- it's a little bewildering to find what you need along with the contextual information. > I noticed the configuration syntax is a bit admin unfriendly.

[Dovecot] sendmail to postfix-dovecot
by Roger Berger 28 Nov '13

28 Nov '13

Hi, I am a newbie to postfix and dovecot so I hope you can help me. I have an old server running sendmail for many years now. On this server I have about 100 domains and 500 users. The users are named as myuser or myuser.dom. People use pop3 and imap for fetching reading their email. I've setup a new server with postfix and dovecot2 on freebsd and managed to get it all working with virtual users. However, now I found out that I overlooked something; People have to login with username(a)domain.tld<mailto:username@domain.tld> on the new server but only use their username on the old server. This means they all have to change their login credentials, which is not an option. Is it possible to do some scripting before authentication where the username is looked up in the database and the right domain is added to the account? If I understand right it is not possible to use system and virtual users together. Thanks, Roger

[Dovecot] Enabling quota
by Andreas Kasenides 27 Nov '13

27 Nov '13

Hello everybody. Sorry if this has been answered before, I just could not find any info. Just point me if that is so. Can somebody please explain why there is no option --with-quota (ot may be --with-fs-quota) for the configure command? As it stands now, at least for the fs back-end the only thing that tells us that Dovecot does not do quotas is after the build/configuration we get dovecot: imap(xxdxx): Error: quotactl(Q_GETQUOTA, csfs9.cs.ucy.ac.cy:/mail) failed: No such file or directory which essentially means that during the build no quota development libraries were found and therefore fs quota will not function. This is rather confusing and the above error does not help much. Note also that "dovecot --build-options" is also silent on this. I suppose other back-ends do not have this requirement since there is no need for such devel libraries. thankx Andreas

[Dovecot] Dsync on a medium sized site
by Skeffling 27 Nov '13

27 Nov '13

Hello, We're looking at changing our current Dovecot setup to use dsync between 2 servers in different data centres to share the load and to provide resilience. We're quite excited about the possibilities! We receive about 100,000 emails a day, to about 10,000 mailboxes - a mix of IMAP and POP3. We'll use Dovecot Deliver via exim to put mail in to the Maildir. Has dsync been used on sites of this size? -Any tips? Do people tend to sync between 2 servers, or do some people use more than 2? I'm interested in other people's experience before setting up some test boxes. Thanks! Andrew.

[Dovecot] Permissions problems

Hi, I have dovecot 2.0.20 running (its an old version, I know, it came from the stable archive at OpenCSW) with Solaris SMF integration working fine. It enables and disables okay. However, I cantt connect to it, it is allowing the connection, but spewing on permissions: Nov 24 17:34:20 proliant-1 dovecot: [ID 583609 mail.info] master: Dovecot v2.0.20 starting up Nov 24 17:34:27 proliant-1 dovecot: [ID 583609 mail.info] imap-login: Login: user=<mark>, method=PLAIN, rip=192.168.1.69, lip=192.168.1.72, mpid=18816 Nov 24 17:34:27 proliant-1 dovecot: [ID 583609 mail.info] imap-login: Login: user=<mark>, method=PLAIN, rip=192.168.1.69, lip=192.168.1.72, mpid=18818 Nov 24 17:34:27 proliant-1 dovecot: [ID 583609 mail.info] imap-login: Login: user=<mark>, method=PLAIN, rip=192.168.1.69, lip=192.168.1.72, mpid=18820 Nov 24 17:34:27 proliant-1 dovecot: [ID 583609 mail.info] imap(mark): Connection closed bytes=17/340 Nov 24 17:34:27 proliant-1 dovecot: [ID 583609 mail.info] imap-login: Login: user=<mark>, method=PLAIN, rip=192.168.1.69, lip=192.168.1.72, mpid=18822 Nov 24 17:34:27 proliant-1 dovecot: [ID 583609 mail.error] imap(mark): Error: rename(/mpool/mail/mark/dovecot.index.log.newlock, /mpool/mail/mark/dovecot.index.log) failed: Permission denied Nov 24 17:34:27 proliant-1 dovecot: [ID 583609 mail.error] imap(mark): Error: rename(/mpool/mail/mark/dovecot-uidlist.tmp, /mpool/mail/mark/dovecot-uidlist) failed: Permission denied Nov 24 17:34:27 proliant-1 dovecot: [ID 583609 mail.error] imap(mark): Error: unlink(/mpool/mail/mark/dovecot-uidlist.tmp) failed: Permission denied Nov 24 17:34:27 proliant-1 dovecot: [ID 583609 mail.error] imap(mark): Error: rename(/mpool/mail/mark/dovecot-uidlist.tmp, /mpool/mail/mark/dovecot-uidlist) failed: Permission denied Nov 24 17:34:27 proliant-1 dovecot: [ID 583609 mail.error] imap(mark): Error: unlink(/mpool/mail/mark/dovecot-uidlist.tmp) failed: Permission denied Nov 24 17:34:27 proliant-1 dovecot: [ID 583609 mail.error] imap(mark): Error: rename(/mpool/mail/mark/dovecot-uidlist.tmp, /mpool/mail/mark/dovecot-uidlist) failed: Permission denied Nov 24 17:34:27 proliant-1 dovecot: [ID 583609 mail.error] imap(mark): Error: unlink(/mpool/mail/mark/dovecot-uidlist.tmp) failed: Permission denied Nov 24 17:34:27 proliant-1 dovecot: [ID 583609 mail.error] imap(mark): Error: rename(/mpool/mail/mark/dovecot-uidlist.tmp, /mpool/mail/mark/dovecot-uidlist) failed: Permission denied Nov 24 17:34:27 proliant-1 dovecot: [ID 583609 mail.error] imap(mark): Error: unlink(/mpool/mail/mark/dovecot-uidlist.tmp) failed: Permission denied If I actually try to copy mail to the inbox of the account it core-dumps and does, and the SMF service drops into maintenance mode which requires re-enabling.

I couldnt think of any other way of creating user-specific folders in the location. As the value suggests, each user gets their own directory on the filesystem for mail. Is this still a ‘safe’ way to do things or would I be better off relocating each user’s ‘home’ directory to the pool somehow?

[Dovecot] Dovecot 2.1 Panic
by Alexandr Sabitov 27 Nov '13

27 Nov '13

Hi, Dovecot 2.1.12 sends panic message when it tries to authenticate some users. Apparently because they use different authentication mechanisms on different email clients at the same time. For example, in debug logs this user uses CRAM-MD5, NTLM and PLAIN in account settings of his email clients. All passwords are stored in plain text (base64) in LDAP. Please advise me what I can tweak to fix this issue ?

[Dovecot] Dovecot software testing and release practice
by Andreas Kasenides 26 Nov '13

26 Nov '13

Since this, it seems, was lost in, the now infamous, 2.2.9 thread I would like to resubmit the following proposal for Timo's consideration. Thanks Timo for doing an excellent job. I believe that the following will add further value to Dovecot in the long run.

I also propose that upon employing above strategy that Timo should come up with a release cycles (long term, short term) with announced targets. Patches should be released as patches strictly as needed, not releases, and should be announced on a low traffic list like he is already doing with releases. OR something along these lines. I know these are growing pains but essential. Email systems are CRITICAL for most of us. Andreas

[Dovecot] Problem with Thunderbird and mailbox with SPECIAL-USE flag
by Sylvain 26 Nov '13

26 Nov '13

Hi ! I have an old Courier IMAP and in front of it, I have put a proxy cache with the great Dovecot. SOGo webmail is connected to the proxy and works great (very very more fast) but I have a problem with Thunderbird : mailbox with « SPECIAL USE » aren't automatically detected. To make that works, I must : - in Dovecot : define the namespace inbox : « prefix = » and « separator = . » - in Thunderbird : force in the account, the personal namespace to "INBOX." and untick « Allow server to exceed namespace » (sorry : personal translation :D). If I define in the namespace inbox as the dovecot wiki said : « prefix = INBOX. » and « separator = . », TB see a sub-folder INBOX and mailbox with special use aren't automatically detected. :-( I must have forgotten a parameter in my Dovecot configuration but I don't see it.. Can you have a look please ? Here my configuration : # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-4-amd64 x86_64 Debian 7.2 auth_debug_passwords = yes auth_mechanisms = plain login disable_plaintext_auth = no first_valid_uid = 100 imapc_host = xxxxxx mail_gid = imapproxy mail_home = /var/local/cache/dovecot/%1Mu/%1.1Mu/%u mail_location = imapc:~/imapc mail_uid = imapproxy namespace inbox { inbox = yes list = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = separator = . type = private } passdb { args = host=xxxxxx port=143 default_fields = userdb_imapc_user=%u userdb_imapc_password=%w driver = imap } protocols = imap ssl_cert = </etc/dovecot/dovecot.pem ssl_key = </etc/dovecot/private/dovecot.pem userdb { driver = prefetch } Sylvain

[Dovecot] 2.2.9
by Nick Edwards 26 Nov '13

26 Nov '13

Timo (since he is the only one that maters here), In past couple of days I have seen 4 people on IRC bitten by 2.2.8 and pigeonhole bug, none of them are on this list, so like all others who want to download and build them, are unaware of the patch, so, given how wide the userbase is with pigeonhole sieve and dovecot, this would or should be considered a serious bug, so my question is Timo, is it not best to immediately push 2.2.9, or should even more server administrators become frustrated and curse waiting two more months until you have a list you think is best putting out a new release, many of them dont like the constant new releases all the time with only minor things, but with a build failure, thats a serious issue.

Noel, I include you in the gang of three, and I only read half the posts on this list. I have no specific reason to, but it isn't a good association. A decade ago I was active on the Pegasus mail and Mercury lists, and names stood out after a while. Unfortunately on this list, the names stand out for a completely different reason - and its not positive. Just chill, everyone. You never know who's going to interview you in a year. Rick

[Dovecot] postfix and dovecot - no emails in new folder
by Don Hill 26 Nov '13

26 Nov '13

Hi. I am working on setting up Dovecot v2.0.9 and postfix 2.6.6 on centos 6.4. I have postfix configured with dovecot using virtual users. Everything seems to be working with the exception of no emails being delivered to the Maildir/new folder. If I touch a file into that folder then the file gets delivered to the email client using imap. I can also send email from the client with no problems. In fact if I look at the logs postfix says the email was delivered to the mailbox. postfix/virtual[27270]: 8652F35C38A8: to=<user(a)domain.tld>, relay=virtual, delay=0.11, delays=0.1/0.01/0/0, dsn=2.0.0, status=sent (delivered to mailbox)$ Here is my dovecot -n output *doveconf: Warning: NOTE: You can get a new clean config file with: doveconf -n > dovecot-new.conf** **doveconf: Warning: Obsolete setting in /etc/dovecot/dovecot.conf:85: protocol { ssl_listen } has been replaced by service { inet_listener { address } }** **# OS: Linux 2.6.32-042stab079.6 x86_64 CentOS release 6.4 (Final) reiserfs** **auth_mechanisms = plain login** **default_login_user = vmail** **first_valid_gid = 5000** **first_valid_uid = 5000** **listen = *** **mail_access_groups = vmail** **mail_location = maildir:/var/vmail/%d/%u/Maildir** **mbox_write_locks = fcntl** **passdb {** ** args = scheme=SHA1 /etc/dovecot/passwd** ** driver = passwd-file** **}** **protocols = imap pop3** **service auth {** ** unix_listener auth-client {** ** group = postfix** ** mode = 0660** ** user = postfix** ** }** ** user = root** **}** **service imap-login {** ** inet_listener imaps {** ** address = *** ** }** ** process_min_avail = 1** ** user = vmail** **}** **service pop3-login {** ** inet_listener pop3s {** ** address = *** ** }** **}** **ssl_cert = </etc/pki/dovecot/certs/dovecot.pem** **ssl_key = </etc/pki/dovecot/private/dovecot.pem** **userdb {** ** args = uid=5000 gid=5000 home=/var/vmail/%d/%u allow_all_users=yes** ** driver = static** **}* Any thoughts?

[Dovecot] Zlib plugin - when does it make sense?
by Frerich Raabe 25 Nov '13

25 Nov '13

Hi, I run a small IMAP server for a dozen guys in the office, serving about 55GB of Maildir. I recently became aware of the Zlib plugin ( http://wiki2.dovecot.org/Plugins/Zlib ) and wondered 1. given that there is about zero CPU load on my IMAP server, is enabling the plugin a no-brainer or are there other things (except CPU load) to consider? 2. For enabling the plugin, I suppose you compress all the existing mail just once and then add 'zlib' to mail_plugins in order to have all future incoming mail saved? Any insight by people familiar with the plugin would be much appreciated - thanks! -- Frerich Raabe - raabe(a)froglogic.com www.froglogic.com - Multi-Platform GUI Testing

by Guillaume Hilt 25 Nov '13

25 Nov '13

Hello again, I'm running Gentoo AMD64 2013 with postfix, mysql, dovecot and dspam : dovecot 2.2.8 (it was working fine with 2.2.6 after doing a chmod 4511 on dspam binary), dspam 3.10.2-r1 and dovecot-antispam-2.0_pre20130429 (recompiled after each dovecot upgrade). I've set dspam to debug, and mail_debug to yes. uid 1001 is user vmail (dovecot is running under vmail) gid 12 is group mail (vmail is a member, with mail,postfix,dspam,dovecot,apache) All the necessary users are trusted in dspam configuration. Here's my plugin settings : antispam_verbose_debug = 1 antispam_debug_target = syslog antispam_backend = dspam antispam_allow_append_to_spam = NO antispam_skip_from_line = NO antispam_spam = Spam antispam_trash = Trash antispam_signature = X-DSPAM-Signature antispam_signature_missing = error antispam_dspam_binary = /usr/bin/dspam antispam_dspam_args = --user;%u;--deliver=;--source=error;--signature=%%s antispam_dspam_spam = --class=spam antispam_dspam_notspam = --class=innocent antispam_dspam_result_header = X-DSPAM-Result When i'm moving an email to the dspam folder, Thunderbird throw me an error : Failed to call dspam (email is dropped in the Spam folder anyway, but a copy stay on my INBOX) ==> /var/log/mail/mail/log <== Nov 25 13:01:04 srv1 dovecot: imap: Debug: Loading modules from directory: /usr/lib64/dovecot Nov 25 13:01:04 srv1 dovecot: imap: Debug: Module loaded: /usr/lib64/dovecot/lib90_antispam_plugin.so Nov 25 13:01:04 srv1 dovecot: imap: Debug: Added userdb setting: plugin/maildir=shadowprojects.org/ghilt/ Nov 25 13:01:04 srv1 dovecot: imap(ghilt(a)shadowprojects.org): Debug: Effective uid=1001, gid=12, home=/home/vmail/shadowprojects.org/ghilt/ Nov 25 13:01:04 srv1 dovecot: imap(ghilt(a)shadowprojects.org): Debug: Namespace inbox: type=private, prefix=, sep=, inbox=yes, hidden=no, list=yes, subscriptions=yes location=maildir:/home/vmail/shadowprojects.org/ghilt/.maildir Nov 25 13:01:04 srv1 dovecot: imap(ghilt(a)shadowprojects.org): Debug: maildir++: root=/home/vmail/shadowprojects.org/ghilt/.maildir, index=, indexpvt=, control=, inbox=/home/vmail/shadowprojects.org/ghilt/.maildir, alt= Nov 25 13:01:04 srv1 dovecot: imap(ghilt(a)shadowprojects.org): Debug: Namespace : Using permissions from /home/vmail/shadowprojects.org/ghilt/.maildir: mode=0770 gid=default Nov 25 13:01:04 srv1 dovecot: imap(ghilt(a)shadowprojects.org): Debug: dspam error:29764 prefix=imap(ghilt(a)shadowprojects.org): Nov 25 13:01:04 srv1 dovecot: imap(ghilt(a)shadowprojects.org): Debug: executing /usr/bin/dspam failed: 13 (uid=1001, gid=12) Nov 25 13:01:04 srv1 dovecot: imap: Error: Nov 25 13:01:04 srv1 dovecot: imap: Error: ==> /var/log/dspam/dspam.debug <== 9976: [11/25/2013 13:12:23] DSPAM Instance Startup 9976: [11/25/2013 13:12:23] input args: /usr/bin/dspam --user ghilt(a)shadowprojects.org --deliver= --source=error --signature=89,52900600118151560172939 --class=spam 9976: [11/25/2013 13:12:23] pass-thru args: 9976: [11/25/2013 13:12:23] processing user ghilt(a)shadowprojects.org 9976: [11/25/2013 13:12:23] uid = 1001, euid = 0, gid = 12, egid = 12 9976: [11/25/2013 13:12:23] loading preferences for user ghilt(a)shadowprojects.org ... 9976: [11/25/2013 13:06:08] DSPAM Instance Shutdown.

[Dovecot] Checkpassword interface for custom password check and home mounting
by Jouko Nikula 25 Nov '13

25 Nov '13

Hi, I'm trying to use the checkpassword interface to do a password check and if the check succeeds I mount the user home directory (including mail) using the users login password and uid. My password check seems to work, but when I add the home directory mounting things seem to stop. Dovecot never logs the result of the password check and nothing happens until the client gets bored and tries again. I added trace to the dovecot's checkpassword-reply and I see that it's really executed, it writes the reply and returns 0 for successful authentication. My dovecot version is 2.1.7. My checkpassword is a setuid binary and the mount is a self made fuse-fs. Any ideas what happens? Are there better ways to do this? Thanks, - Jouko

Hi, I'm trying to use the checkpassword interface to do a password check and if the check succeeds I mount the user home directory (including mail) using the users login password and uid. Things work well if I do the mount manually, but when I add the home directory mounting to checkpassword things seem to stop. Dovecot logs the result of the password check, but doesn't send the result to client.

[Dovecot] quota warning by script fails
by Jimmy Koerting 24 Nov '13

24 Nov '13

Hello! I looked around all online resources I found, but I'm not able to find my failure. So any help would be welcome! The problem arises with an dovecot 2.2.6 on a 9.2 FreeBSD RELEASE in a jailed environment. I have the following config settings regarding quota (which works in general, but just without calling the script): /etc/dovecot/conf.d/90-quota.conf: ... plugin { quota_warning = storage=95%% quota-warning 95 %u quota_warning2 = storage=80%% quota-warning 80 %u } service quota-warning { executable = script /usr/sbin/quota-warning.sh unix_listener quota-warning { mode = 0666 } } ... script:

[Dovecot] dovecot patch: do scanf correctly
by Jann Horn 24 Nov '13

24 Nov '13

As far as I can tell, there are two places in which dovecot does not use scanf properly. This patch should fix that. -------------------------------------------------------------------------------- diff -r 8a3d0426f514 src/lib-dns/dns-lookup.c --- a/src/lib-dns/dns-lookup.c Sat Nov 23 23:22:09 2013 +0000 +++ b/src/lib-dns/dns-lookup.c Sun Nov 24 06:30:12 2013 +0100 @@ -102,7 +102,7 @@ } /* first line: <ret> <ip count> */ if (sscanf(line, "%d %u", &result->ret, - &result->ips_count) == 0) + &result->ips_count) != 2) return -1; if (result->ret != 0) { result->error = net_gethosterror(result->ret); diff -r 8a3d0426f514 src/lib-settings/settings.c --- a/src/lib-settings/settings.c Sat Nov 23 23:22:09 2013 +0000 +++ b/src/lib-settings/settings.c Sun Nov 24 06:30:12 2013 +0100 @@ -44,7 +44,7 @@ { int num; - if (!sscanf(value, "%i", &num) || num < 0) + if (sscanf(value, "%i", &num) != 1 || num < 0) return t_strconcat("Invalid number: ", value, NULL); *result = num; return NULL; -------------------------------------------------------------------------------- Specifically, both invocations disregard that sscanf("", "%d", &num) and similar make sscanf return EOF (-1 on my system) and the first invocation also does not account for the case that the second argument is not matched.

[Dovecot] Dict client unescaping sieve script
by Joshua Perry 22 Nov '13

22 Nov '13

I've created a dict service that listens on a unix socket and answers queries for sieve scripts (among other things). As I understand it (from the source code at http://hg.dovecot.org/dovecot-2.2/file/tip/src/lib-dict/dict-client.c) the dict client will unescape \001n, \001t, and \0011 to line feeds, tabs, and the \001 character respectively. In my service I am escaping those three characters in my response (if I don't escape them the line-oriented nature of the protocol causes a failure for multiline sieve scripts) but every time LDA attempts to process a sieve script I get an error in the logs (see below) showing sieve choking on \001 characters. Is there some configuration value I've missed or something? *dovecot log* Nov 8 23:04:54 www dovecot: lmtp(29940, josh(a)redacted.com) pxg7JxZufVL0dAAAPhZyyg: sieve: failed to compile script dict:proxy:/var/run/dovecot-auth.sock:sieve;name=main script (view user logfile /var/mail/vhosts/redacted.com/josh/.dovecot.sieve.log for more information) *.dovecot.sieve.log* sieve: info: started log at Nov 08 16:14:38. main script: line 1: error: unexpected character(s) starting with 0x01. main script: line 1: error: unexpected unknown characters found at (the presumed) end of file. main script: error: parse failed.

[Dovecot] removing html via dovecot/sieve
by Bonz 22 Nov '13

22 Nov '13

is there a howto or similar for configuring dovecot as a user to strip mime. ideally i would like all html copies deleted, but graphics, etc dumped to ~/public_html and replaced with a url. i have a super crappy link so html, etc usually jams my spool. i can usually wget things however hence this desired approach. bonz.

[Dovecot] Personal Sieve Resieving Default Sieve?
by Jim McNamara 22 Nov '13

22 Nov '13

Hello all. In my dovecot install we have a default.sieve script which filters incoming mail based on the subdomain of our main domain. All it does is if the mail comes from A.domain.com move in to folder A in inbox, and if it comes from B.domain.com, move to folder B also in inbox. In my personal sieve script, I'd like to grab a particular email each day that the default.sieve saw coming from A.domain.com and moved it to folder A, and either copy or move it to another folder, C. My google-fu was weak while looking for second sieve passes undoing the first, so I thought it best to ask here. Thanks for your time.

[Dovecot] dsync-2.2.7 incorrectly synchronizes subscription status of renamed mailbox
by Karol Jurak 21 Nov '13

21 Nov '13

Hi, It seems that dsync-2.2.7 doesn't correctly synchronize subscription status of a renamed mailbox. The situation is as follows. There are two servers: A and B, and a test user test_mdbox. Mailboxes (mdbox) of this user on both servers are synchronized. Specifically on both of them there is a (subscribed) Test1 mailbox. Replication plugin is disabled. I rename Test1 to Test2 on A with Thunderbird. The output of 'doveadm mailbox list', contents of subscriptions file and the output of 'doveadm dump -t mailboxlog dovecot.mailbox.log' (below) confirm that the rename succeeded on A. #2976: rename 2b84f621c0fd4ba8bd514c5c43ab9a89 (2013-11-19 14:30:35) #3000: subscribe 2b84f621c0fd4ba8bd514c5c43ab9a89 (2013-11-19 14:30:35) #3024: unsubscribe 99ea7bf70f6e69ad71659995677b43f8 (2013-11-19 14:30:35) Subsequently I run 'doveadm sync -u test_mdbox remote:B'. Nothing changes on A. On B 'doveadm mailbox list' shows that Test1 was renamed to Test2, but subscriptions file still contains Test1 and not Test2. The output of 'doveadm dump -t mailboxlog dovecot.mailbox.log' confirms that only rename was performed: #2160: rename 2b84f621c0fd4ba8bd514c5c43ab9a89 (2013-11-19 14:57:22) Only another 'doveadm sync -u test_mdbox remote:B' fixes subscriptions on B. The following records are added to dovecot.mailbox.log: #2184: unsubscribe 99ea7bf70f6e69ad71659995677b43f8 (2013-11-19 15:00:32) #2208: subscribe 2b84f621c0fd4ba8bd514c5c43ab9a89 (2013-11-19 15:00:32) -- Karol Jurak

[Dovecot] Enable Rawlog from userdb in Dovecot v2.2
by Steffen Kaiser 21 Nov '13

21 Nov '13

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, how do I enable Rawlog for one person only? http://wiki2.dovecot.org/Debugging/Rawlog describes how to enable the postlogin script for all users. Rawlog gets active only, if the dovecot.rawlog directory exists. So far, it's working. However. I suspect that there is some notable overhead in this chain, so I tried to enable rawlog via userdb extra fields. So setup the config as: service imap { executable = imap } service postlogin { executable = script-login -d rawlog unix_listener postlogin { } } In the userdb extra fields I tried: service/imap/executable=imap postlogin Log entry: imap: Debug: Unknown userdb setting: plugin/service/imap/executable=imap postlogin and: service imap/executable=imap postlogin (note the space between service imap) Log entry: imap: Debug: Unknown userdb setting: plugin/service imap/executable=imap postlogin - -- Steffen Kaiser -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iQEVAwUBUoDzAV3r2wJMiz2NAQJxgwf+NCaABKspwVffTpQqVIAdlXGi2gUrRd29 1Ic82v5xqx8jMQ+UxnKNJBX2jgs87GITWpPtTXUVS8H6piNDJrcAxT0lIun0l4Ob 4riQh01HrMjwWORAAWvHHQWZbyiDu8i2h8PjQAG/8idpCt0lCmmr2DyRQwSx+7lf JgfxfccYMRhAHtethm82cjWs3Q/M9deO+ds+aLwxGhDaYxHcU8vD3ESuhqnsR4Bh VqemH3wBADpfKH3ThRKknsfGfEU5d8bcz1GzhOcjfwC24kPsei4k9wcDAy+moyk1 8vPYyvWnhhfb0/yiO3eLpX0mdlM9Iur1X3MFvA0tFwnB8RtuqZGw3g== =/TtK -----END PGP SIGNATURE-----

[Dovecot] Reset vacation lda-dupes database
by Mike Selner ＠ Yahoo 20 Nov '13

20 Nov '13

Hello, I have dovecot 2.2.6 and pignenhole 0.4.2 running on freebsd9.1. We have a mix of unix users (/home/user) and postfixadmin users (/home/vmail/domain/user). I am using dovecot managesive with afterlogic webmail which has a managesieve plugin to set the out of office message. All works fine. I have sieve_vacation_default_period set to 1d. The problem I'm trying to solve is that users set their vacation message and want to test it. So they have their colleagues send them multiple test messages and want to make sure it works. Of course only the first message gets an auto-reply. I tell them that the auto responder only sends one message per day per sender but they would like to test it with a new message etc. So I have to remove their .lda-dupes file manually so they can try again. My previous autoresponder setup (squirrelmail) used a .forward technique and removed the vacation database when they turned the responder from off to on, and this worked well for the above issue. Is there a solution for dovecot managesieve which will remove or reset the .lda-dupes file whenever a new sieve file is uploaded? Or another solution that will reset the "vacation timer" when the user turns vacation from off to on? Thank you Mike

[Dovecot] UID order vs date order
by Torbjorn Jansson 20 Nov '13

20 Nov '13

Hi i have recently moved a mailbox to dovecot and intend to use it via imap and i have run into a problem. when i imported the mails apparently the UID order got reversed compared to the date order, result is that some clients like on android devices download the oldest mails instead of newest. it is not so interesting to have several years old mail show up at the top of the mailbox. is there any way of convincing dovecot to renumber the mails by date order instead? i have tried to delete the dovecot-uidlist and dovecont.index* files in an unimportant folder and the only thing that happens was that all of the mails got renumbered in the wrong order again (lower numbers but still same problem) any advice? i cant be the only one that have run into this.

[Dovecot] Dovecot 2.2.5: Panic: file mail-transaction-log.c: line 350 (mail_transaction_log_set_mailbox_sync_pos)
by Rob Dosogne 20 Nov '13

Hello, I have been seeing an issue with Dovecot 2.2.5 (which is the current version packaged by cPanel). This is happening with any action that tries to access the mailbox index via IMAP. This log and debug information comes from a force-resync attempt, however, the same errors are logged when the user tries to open the mailbox or move a message to it. (User, domain, and IPs in log have been changed for privacy reasons). System is a CentOS 5.10 (x64) VPS under Virtuozzo 4.0, and is not OOMing or hitting any container limits.

[Dovecot] Quick question on sieve
by LuKreme 20 Nov '13

20 Nov '13

I have a procmail recipe that does the majority of my heavy lifting for my mailing lists. It's pretty straightforward, but as I understand it, this isn't something sieve can do: # [ ] contains a space and a tab :0 * 9876543210^0 ^(List-Id:.*<|X-Mailing-List:[ ]*)\/[-A-z0-9_+]+ * 9876543210^0 ^(List-Post:[ ]*(<mailto:)?|List-Owner:[ ]*(<mailto:)?owner-)\/[-A-Z0-9_+]+ * 9876543210^0 ^(Sender:[ ]*owner-|X-BeenThere:[ ]*|Delivered-To:[ ]*mailing list )\/[-A-Za-z0-9_+]+ * 9876543210^0 ^Sender:.* List"? <(mailto:)?\/[-A-Z0-9_+]+ { LISTNAME=$MATCH } Basically, it checks the headers for any one of the headers List-ID: List-Post: List-Owner: Sender: owner- X-BeenThere: Delivered-To: Sender:.*List and parses out the name of the list, writing it to the LISTNAME variable For the vast majority of mailing lists the message is then written to .$LISTNAME/ This means that, by default, a new mailing list is automatically sorted to its own mailbox without my doing anything at all. Is this something hat Sieve can do? Does it have variable assignment? -- <div id="me"><div id="Dennis Miller>It's just my opinion. I could be wrong.</div>But I'm not.</div>

[Dovecot] NTLM authentication in Thunderbird vs Outlook 2010.
by Alexandr Sabitov 20 Nov '13

20 Nov '13

Hi List, I am using the Dovecot 2.1.12 with NTLM authentication enabled. The Dovecot is set up in cluster with directors, 60 000 connections simultaneously. I have noticed that NTLM authentication is processed differently for Thunderbird and Outlook 2010 users. It actually makes Outlook 2010 clients query LDAP more often that Thunderbird ones which is not good potentially for overall performance. Dovecot do not see a domain in NTLM Type 3 message but it does exist there. Could somebody explain please why it is happening?

[Dovecot] Question about dovecot 2.2 and LIST command
by Jonathan Siegle 19 Nov '13

19 Nov '13

I am running dovecot 2.2 changeset 16983:d925674c4329 on AIX. We use mbox files with the "/" delimter. I have an imap protocol question. When I do: 1 list directory1/ * 1 OK List completed. Is that the correct answer? If I do 1 list "" * it shows * LIST (\Noselect \HasChildren) "/" "directory1" I forget why I think that even with the delimiter, I should see some information about it. Is this a silly test that no imap client does? Thanks, Jonathan

[Dovecot] Crash in dovecot 2.2.6
by Ed W 19 Nov '13

19 Nov '13

Hi, I recently upgraded from a dovecot 2.1 version to 2.2.6. I now have a single user who occasionally triggers a crash (just this one user it seems?). The user connects via LiveMail (v14.0.8117.) and IMAP.

[Dovecot] Problem migration from cyrus with imapc

19 Nov '13

Hi all, i have problem with namespace when i try to migrate from cyrus to dovecot with imapc. If i login to the old cyrus i get: telnet 192.168.8.164 143 Trying 192.168.8.164...

Can everyone explain me where the extra "prefix INBOX" came from and how i can resolve that? The migration should be transparent for users. Did you need any extra informations? 192.168.8.164 is a dovecot-proxy. Consolelog of dsync and doveconf -n follows.

[Dovecot] Mail filters in incoming message
by Jos Chrispijn 19 Nov '13

19 Nov '13

With my iMap client, I use various mail rules to move specific email to the right mail folders. Downside of that is that is this mailclient is not online, all email is stuck in my inbox, which makes reading email by mobile phone kind of chaotic. I have seen several Pigeonhole Sieve examples, but I would like to know if there is a nub solution (I am not a programmer) to run filters when they enter my mail server (Postfix 2.10.2,1 icw Dovecot 1.2.17) or if there is a user friendly GUI available to set these filters? Perhaps Anyone interested to create such a GUI? Best regards, Jos Chrispijn --- Artificial intelligence is no match for natural stupidity

[Dovecot] wiki links
by Timo Sirainen 19 Nov '13

19 Nov '13

Since google points only to wiki.dovecot.org, I changed it to now redirect all requests to wiki2. I didn’t want to originally do this to avoid breaking all old links, but maybe it’s not that bad anymore. Most links exist anyway for wiki2 too.

[Dovecot] Calling dovecot-lda from maildrop/shell
by Florian Lindner 19 Nov '13

19 Nov '13

Hello, I want to make final delivery for some of my mailboxes using dovecot-lda, since I'm interested in using sieve. My usual MDA which is called from postfix is and will be maildrop. First try was to call dovecot-lda from command line: /usr/lib/dovecot/dovecot-lda -d spam(a)xgm.de < testmail which gave return code 75 (EX_TEMPFAIL) and logged: dovecot: auth-worker(3533): mysql(localhost): Connected to database system dovecot: imap-login: Login: user=<spam(a)xgm.de>, method=PLAIN, rip=::1, lip=::1, mpid=3535, secured, session=<jwXWP3HrwgAAAAAAAAAAAAAAAAAAAAAB> dovecot: imap(spam(a)xgm.de): Disconnected: Logged out in=91 out=830 dovecot: lda(spam(a)xgm.de): Error: user spam(a)xgm.de: Initialization failed: Namespace '': Mail storage autodetection failed with home=/home/flindner/Mail/spam dovecot: lda(spam(a)xgm.de): Fatal: Invalid user settings. Refer to server log for more information. My userdb/password is like that home == maildir == /home/flindner/Mail/spam (without prefixed "maildir:"). It works fine for dovecot-imap, it detects that spam is a maildir. I've also tried prefixing home and or maildir with "maildir:" or calling: HOME=maildir:~/Mail/spam /usr/lib/dovecot/dovecot-lda < testmail which gave: dovecot: lda: Error: user flindner: Relative home directory paths not supported: maildir:/home/flindner/Mail/spam dovecot: lda: Fatal: Invalid user settings. Refer to server log for more information. What is the problem with the LDA here? Thanks, Florian

[Dovecot] Dovecot Listescape plugin problem
by vupibi 18 Nov '13

18 Nov '13

Dovecot Version: 2.0.19 I'm on Ubuntu 12.04.3 using Zentyal with Dovecot for a mail Server. What I try to setup is the possibility to use slashes ("/") in folder names inside the IMAP account. Regularly if I name a folder "foo/bar", the system creates me a folder named "bar" inside a folder named "foo". Listescape should give me the possibility but it does not work. It's not possible for me to write inside the "/etc/dovecot/dovecot.conf" because Zentyal will overwrite all changes when restarting the server. So my Configs are in "/etc/dovecot/extra.conf" and look like this: mail_plugins = listescape (i tried "mail_plugins = $mail_plugins listescape" as well, no success) namespace inbox { separator = "\\" prefix = inbox = yes hidden = no list = yes location = maildir:/var/vmail/%d/%n:LAYOUT=fs } My dovecot -n output # 2.0.19: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-55-generic x86_64 Ubuntu 12.04.3 LTS ext4 auth_gssapi_hostname = mailand.sxps.local auth_krb5_keytab = /etc/dovecot/dovecot.keytab auth_mechanisms = gssapi plain first_valid_gid = 116 first_valid_uid = 108 log_timestamp = "%Y-%m-%d %H:%M:%S " mail_gid = 116 mail_home = /var/vmail/sieve/%d/%u mail_location = maildir:/var/vmail/%$ mail_plugins = listescape mail_uid = 108 managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave namespace inbox { hidden = no inbox = yes list = yes location = maildir:/var/vmail/%d/%n:LAYOUT=fs prefix = separator = \ } passdb { args = /etc/dovecot/dovecot-ldap.conf driver = ldap } plugin { autocreate = Trash autocreate2 = Spam autocreate3 = Sent autocreate4 = Drafts autosubscribe = Trash autosubscribe2 = Spam autosubscribe3 = Sent autosubscribe4 = Drafts quota = maildir:User quota quota_rule = *:storage=0 sieve = /var/vmail/sieve/%d/%u/sieve-script sieve_global_path = /var/vmail/sieve/default.sieve sieve_storage = /var/vmail/sieve/%d/%u } protocols = pop3 imap sieve service auth { executable = /usr/lib/dovecot/auth unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-master { group = ebox mode = 0600 user = ebox } user = dovecot } service imap-login { inet_listener imap { port = 143 } inet_listener imaps { port = 993 } } service managesieve-login { inet_listener sieve { port = 4190 } } service pop3-login { inet_listener pop3 { port = 110 } inet_listener pop3s { port = 995 } } ssl_cert = </etc/dovecot/ssl/dovecot.pem ssl_key = </etc/dovecot/ssl/dovecot.pem userdb { args = /etc/dovecot/dovecot-ldap.conf driver = ldap } protocol imap { mail_plugins = quota imap_quota autocreate } protocol pop3 { mail_plugins = quota } protocol lda { auth_socket_path = /var/run/dovecot/auth-master mail_plugins = sieve quota postmaster_address = admin(a)sxps.eu } Any Ideas? -- View this message in context: http://dovecot.2317879.n4.nabble.com/Dovecot-Listescape-plugin-problem-tp45… Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] Experience with ALTStorage on NFS mount
by Urban Loesch 18 Nov '13

18 Nov '13

Hi, we are thinking about storing older mails (eg. safed before 6 months) to an alternative storage mounted via NFS from an external storage box. Some technical details - the storage will be connected via 1 gbit ethernet. Access will be allowed from different dovecot servers, but only to divided directories for each dovecot. - storage has the option to use RAID 5 or 6. Max. amount of Disks are 15. - the index files and the primary storage are just divided in two different directories and are stored local on SAS disks with RAID 10 - current mail_location config is: mdbox:/home/vmail/%d/%n:INDEX=/home/dovecotindex/%d/%n - future mail_location config shoudl look like: mdbox:/home/vmail/%d/%n:INDEX=/home/dovecotindex/%d/%n:ALT=/home/extstorage/vmail/%d/%n My question is, if someone of you have already experience in such a setup with NFS? And are there some tuning tips for NFS? We have not many experience with NFS right now. Or perhaps is there some better solution? Many thanks and regards Urban

A database is a database, a master is a master, and a slave is a slave our mysql has never had problem, not a single one, its why I'm so annoyed dovecot is talking to master when it doesn't need to

[Dovecot] I wrote CheckPassword Shell example for Dovecot
by Nicolay Vizovitin 18 Nov '13

18 Nov '13

Hello, Seeing as there are not too many Dovecot CheckPassword driver usage examples on the Internet, I wrote one using Shell script. You can see post about it here: http://devblog.plesk.com/2013/11/shell-checkpassword-authentication-in-dove…. The post also has a link to Mercurial repository with the example. Feel free to use the example as you see fit. You may even include it into documentation (or link to it), if you'd like. Thanks for such great software as Dovecot! -- Best regards, Nick

Anyway I?ve noticed once that 10.9 Mail didn?t show some of my mails until I restarted it. Then there are several other annoying bugs.. I really shouldn?t have upgraded yet. We are running Dovecot 2.0.12, and I already have the Mavericks Mail patch of a few days ago. Still requires a restart to get new mail.

[Dovecot] Issue with Mavericks Mail Client
by Ken Mandelberg 17 Nov '13

17 Nov '13

We run a dovecot mailserver. One of the clients I use is a Mac Laptop. Recently I upgraded from Mountain Lion (10.8) to Mavericks (10.9). Under 10.8 it worked fine. On 10.9 it syncs up when I invoke the client, but after a while stops getting updates. Most of my mail clients are on Linux (thunderbird) or Android (K9) and I admit that several run against my very large INBOX simultaneously. The one of the 10.9 Mac laptop is the only one with this issue. Is there something known about the new 10.9 Mail client on the Mac that would lose sync against dovecot?

[Dovecot] Replication Setup
by springy 16 Nov '13

16 Nov '13

Hi, I am attempting to setup replication between two hosts running Centos 6.4 and Dovecot 2.2.5. My users are real unix users, so I am trying to run the replication as root user, so that it has the appropriate permissions to run. I have two users at present syd1 and syd2, and the two hosts are called syd1 and syd2 as well. When I start Dovecot with the settings below, nothing happens, and the two mailboxes remain un-synced. There are no errors in the log, just Dovecot starting successfully.

Hello, Running Gentoo AMD64 2013 with postfix, mysql, dovecot and dspam, i finally upgraded to dovecot 2.X. I'm running dovecot 2.2.6, dspam 3.10.2-r1 and dovecot-antispam-2.0_pre20130429. My DSPAM configuration hasn't changed between dovecot 1.X and 2.X.

[Dovecot] Sieve script problem (don't know if is it possible to do this)
by Yanko Hernández Álvarez 15 Nov '13

15 Nov '13

Hello: I'm loosing my mind trying to classify my outgoing messages with sieve-test (2.0.9, centos 6.4). It came to the point I think it's not even possible with a sieve script. I need to classify my outgoing messages in three folders: 1- To my department (@dept.example.com) 2- To my company (@example.com, @anyotherdept.example.com) (anyotherdept.example.com as in a way to say "any other domain that ends with 'example.com', but not 'dept.example.com'") 3- To the rest of the word (@any.other.domain) The problematic requirement is I need to make a copy in EVERY IMAP folder that applies. For instance: for an email such as ---- From: myuser(a)dept.example.com To: user(a)dept.example.com, user(a)example.com, user(a)other.domain ... ---- I need to make a copy to all folders: Dept (because of user(a)dept.example.com) Company (because of user(a)example.com) and Rest (because of user(a)other.domain) Rule for #1 is simple: ----- if address :matches :domain "To" "dept.example.com" { fileinto: "Dept"; } ----- Rule for #2, I don't know how to declare it: I don't know how to make a rule that matches "example.com" (or anyotherdept.example.com) and not "dept.example.com". if allof(address :matches :domain "To" "example.com", not address :matches :domain "To" "dept.example.com") { fileinto: "Company"; } ... doesn't work, because user(a)dept.example.com matches (address :matches :domain "To" "example.com"), but it doesn't matches (not address :matches :domain "To" "dept.example.com"). "user(a)example.com" matches both conditions, but sieve-test stops on the first email address with a "not matches" As for Rule #3: I don't know how to do it either, it should be the same as Rule #2, (with different parameters of course). A sieve script should be capable to do this, but it seems that I'm loosing something. Does any one knows how to do this? Kind regards Yanko PS: English is not my native language. Please forgive me any mistakes/misspellings/etc I made.

[Dovecot] Fwd: Sieve script problem (don't know if is it possible to do this)
by Yanko Hernández Álvarez 15 Nov '13

15 Nov '13

Ok, let simplify a little bit the problem: Forget about outgoing or incoming mail. Forget about IMAP or SMTP. You have a ton of emails in raw form (RFC-XXX, don’t remember the exact number right now) you want to classify… and you think: “Sieve is a language made to do exactly that kind of task… If only I could use the same mechanism dovecot-lda uses! Oh, wait… “sieve-test –e” does exactly that!!! I could use it!!!”… but so far… no success. Now, a little more context. I want to leave a copy (a historical record) of every email (work related) I received/sent. The processing/classification doesn’t have to be in real time, it can be on “down time/offline/later/scheduled”. Sent messages are hard, because of the several senders and the several copies on several folders. But I can work around it, with various tricks (bcc, different headers, etc.) and adjusting the processing sieve script. I can train myself –The interest is mine after all!-, and that’s OK. But I can’t train other people to suit my needs. And received messages are JUST AS HARD. Because I want to classify them using the same rules. I also want to keep context, to record all things work related, not only what I said, but also what was said by others, using the same rules (which by the way, are many more than the restricted example I posted). Besides, I want the PC do all the work for me, not the other way around. I think “Sieve must be capable of doing it! This is the kind of things sieve was designed for!” is a reasonable idea. But so far, no success… :-( Now, let me see all the replies in detail...

[Dovecot] Establing a GMail like workflow
by Florian Lindner 15 Nov '13

15 Nov '13

Hello! I'm about to migrate my mails from GMail back to my self hosted solution, using Dovecot imap server. I really liked gmail workflow: - (Almost) all mail goes to inbox. - Most mail is read and not important anymore, it is archived and moved to "all messages". - Inbox stays more or less clean, with only mails that are still of some interest. - Mail (except Spam) is never deleted, just archived. How can I achieve such a workflow using Dovecot and some MUA (Roundcube and probably KMail). - I can simply delete messages that I want to archive, Trash will never be purged. Problems: Some mail clients have settings like "Purge Trash at exit", so my mail is always in danger of being deleted accidently. Futhermore it does not really have the semantics of what I am actually doing. - Instead of deleting messages for archiving, move them to some Archiv folder. Since archiving is a very frequent action this involves much more cliks in the MUA than just deleting. Or some configuration change in the client. How would you do that? I'm also open to entirely different suggestions! What I want are basically these things: - Never delete legitimate mail - Use the Inbox as a workspace for mails that are still of some interest. This can also be quite old mail, time based archiving does not work. - Have some kind of mail archive. Thanks! Florian

[Dovecot] Dovecot login slow
by Marc Perkel 15 Nov '13

15 Nov '13

Can't figure out why the login is slow. I telnet to port 143 on localhost. I type: 0 login user password Takes about 10 seconds and it lets me in. I'm using MYSQL and it's a small indexed database on a fast server so it's not the mysql query that's slowing it down. At least I don't think it is. But - kind of stumped. Just wondering if there's something obvious I'm overlooking.

[Dovecot] Executing a wget? or clicking on a link in inbound email?
by Voytek 14 Nov '13

14 Nov '13

I use Dovecot, but all I know about Dovecot is that's it is an IMAP server, and, I know that it includes lots of other stuff that I see discussed on this list, but I know nothing about it. I have a situation that, maybe once a week, I get an html only email that contains 3 clickable links. I would like, on receipt of such email, auto click the first link (perhaps execute a wget to do so? or ?) Can something like this be done, which of the tools, what docs to look at? link is like so http://llll.domain.tld/irportal?id=a0000000006hWO4AAM0000000000KlOrcAAF1111… Dovecot 2.09 Centos (apologies for blank post I've just sent) -- Sent from Kaiten Mail.

[Dovecot] Autocreation of sieve filters
by Angel L. Mateo 14 Nov '13

14 Nov '13

Hello, Is there any way to create a predefined sieve filters during mailbox autocreation? What I want is that my user's mailboxes are automatically created (using mailbox option in namespaces) but I want them to have a predefined sieve script. Using a postlogin script could be an idea, but I'd prefer an automatic one, because postlogin only will filter after first user login -- Angel L.

[Dovecot] Dovecot 2.0.9 Quota Limit issues
by David Johnson 13 Nov '13

13 Nov '13

Hello, I've tried searching for information regarding this problem but haven't found anything. Currently I have a Dovecot 2.0.9 with virtual users from a SQL table. Right now I'm only using global quota limits. Here is my quota setup: plugin { quota = maildir:User quota quota_rule = *:storage=3G quota_rule2 = Trash:storage=+100M quota_rule3 = Archive:storage=+1G quota_rule4 = Archive/2013:storage=+1G quota_rule5 = Junk:ignore } According to the documentation this should allow the Archive folder to have an additional 1G in it that is not counted toward the global 3G. However I have users who have 2G in the Archive folder, and about 1G elsewhere. At this point they stop receiving emails due to quota exceeded. doveadm quota get -u <user> displays this: Quota name Type Value Limit % User quota STORAGE 3150312 3145728 100 User quota MESSAGE 8271 - 0 If I change Archive:storage=+1G to Archive:ignore then they can receive emails again. After the change doveadm quota get -u displays this: Quota name Type Value Limit % User quota STORAGE 1266885 3145728 40 User quota MESSAGE 8271 - 0 Is there something I'm missing as to why this setup isn't working? Thanks! -- David J.

[Dovecot] Dovecot MTA
by Timo Sirainen 12 Nov '13

12 Nov '13

Hi all, I've never really wanted to create my own MTA, because I like Postfix quite a lot. And I always thought it would require a horribly lot of time to be able to create something that was anywhere even close to having Postfix's features. (I would shudder to even think about recreating Dovecot from scratch nowadays.) But slowly over time I've also been thinking of ways how things could be done a bit better, and I think I have enough ideas to start thinking about Dovecot MTA more seriously in a few more months (after my current busy schedule calms down a bit). And (unlike Dovecot!) I'm not planning on taking over the world with the MTA (or at least not very quickly), but it would definitely be useful for many installations I know of. My main design goals for the MTA are: * In normal load don't queue mails, just continue delivering the mail through different processes/services until it succeeds or fails, and only after that return ok/failure to the SMTP client. So there's no (forced) post-queue filtering, everything would normally happen pre-queue. This is required because in Germany (and EU in general?) you aren't allowed to just drop spams after SMTP server has responsed OK to the client, even if you’re 100% sure it’s a spam. So this would also mean that the SMTP DATA replies will come more slowly, which means that the SMTP server must be able to handle a lot more concurrent SMTP connections, which means that in large installations the smtpd process must be able to asynchronously handle multiple SMTP client connections. * In some cases you can't really avoid placing mails into a queue. This could be because of temporary failures or maybe because of an abnormal load spike. A mail queue in local disk isn't very nice though, because if the local disk dies, the queued mails are lost. Dovecot MTA will allow the queue to be in object storage and it will also likely support replication (similar to current dsync replication). In both of these cases if a server dies, another server can quickly take over its queue and continue handling it. * Dovecot MTA is a new product, which means we can add some requirements to how it's being used, especially related to securely sending emails between servers. It could do a bunch of checks at startup and fail to even start if everything isn't correct. Here are some things I had in mind - not sure if all of these are good ideas or not: - Require DKIM configuration. All outgoing mails will be DKIM signed. - Require the domain’s DNS to contain _submission._tcp SRV record (and actually might as well require _imap._tcp too) - Require SSL certificates to be configured and always allow remote to use STARTTLS - Require DANE TLSA record to exist and match the server's configured SSL cert - Have very good (and strict?) DNSSEC support. If we know a remote server is supposed to have valid DNSSEC entries, but doesn't, fail to deliver mail entirely? - Add a new DNS record that advertises this is a Dovecot MTA (or compatible). If such entry is found (especially when correctness is guaranteed by DNSSEC), the email sender can assume that certain features exist and work correctly. If they don't, it could indicate an attack and the mail sending should be retried later. This DNS record would of course be good to try to standardize. * Configuration: It would take years to implement all of the settings that Postfix has, but I think it's not going to be necessary. In fact I think the number of new settings to dovecot.conf that Dovecot MTA requires would be very minimal. Instead nearly all of the configuration could be done using Sieve scripts. We'd need to implement some new MTA-specific Sieve extensions and a few core features/configurations/databases that the scripts can use, but after that there wouldn't be really any limits to what could be done with them. * Try to implement as many existing interfaces as possible (e.g. Milter and various Postfix APIs like policy servers) so that it wouldn’t be necessary to reimplement all the tools and filters. So perhaps something like this could be done in time for Dovecot v2.4. Any thoughts/ideas/suggestions?

This won't protect against: * NSA listening in on the mails when they arrive. * NSA taking a backup of your mails and wait for your first attempt to read them - at which time they'll have your private key in plain text. It seems like a much wider protection to just keep you private key for your self. /Peter

[Dovecot] Can't get sieve/managedsieve working
by Alter Depp 11 Nov '13

Hi, I am running dovecot 2.1.7 for a while, with roundcube webmail frontend 0.9.5 . Now I wanted to add sieve to filter mails. Unfortunately most tutorials are for dovecot 1.x but I'm running dovecot 2 on debian wheezy. I could upload some scripst with sieve-connect, checked and activated them. When I try to edit filters with thunderbird sieve plugin 0.2.2 nothing happens. If I try to edit filters with roundcube managesieve plugin nothing happens, too, but I get some errors in logfile: > roundcube: "Authentication failed."

[Dovecot] Getting debug output from antispam plugin with dspam

The bug is related to the sieve module in /src/lib-sieve/plugins/notify/ext-notify-common.c:266. The line contains only a check if mail_get_headers_utf8 returns an error. So the workaround for this line would be to add a check if header[0] is not NULL. if ( (mail_get_headers_utf8(msgdata->mail, "subject", &header) >= 0) && header[0] ) str_append(out_msg, header[0]); IMHO this patch should be applied to the "$from$" replacement as well. The comments in the dovecot's header file says for mail_get_headers: Returns -1 if error, 0 otherwise (with or without headers found). hope it helps, Regards Christian Ferbar

[Dovecot] Question about folder sharing
by Achim Gottinger 09 Nov '13

09 Nov '13

Hi, I run dovecot (2.1.7) on debian wheezy in conjuniction with postfix, samba4 (as ldap backend) and sogo. I configured folder sharing but have an few issues. With my current config users can share the inbox and other folders. If the acl allows creatings subfolders this does work for all folders beside inbox. What i want to archiev is the following: If an user shares his inbox, others should be able to create subfolders and those should inherit the inboxe's acl. All subfolders of inbox should appear as folders at root level and not as subfolders of the inbox. I thought this can be done by setting the prefix of namespace inbox to INBOX/. I did this and changed the IMAP Server Folder setting in thunderbird to INBOX (like it was earlier when i used courier). Now subfolders created at rootlevel or as subfolders of the inbox appear on rootlevel in thunderbird but they do not inherit the acl's from inbox. Is there an way to achive this? doveconf -n # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-4-amd64 x86_64 Debian 7.2 ext4 auth_debug = yes auth_gssapi_hostname = $ALL auth_krb5_keytab = /etc/dovecot/dovecot.keytab auth_master_user_separator = % auth_mechanisms = plain login gssapi auth_username_chars = abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@% auth_username_format = %n auth_verbose = yes debug_log_path = syslog disable_plaintext_auth = no first_valid_gid = 998 first_valid_uid = 998 info_log_path = syslog mail_debug = yes mail_gid = 998 mail_home = /home/vmail/%u mail_location = maildir:/home/vmail/%u/mail mail_plugins = acl mail_shared_explicit_inbox = no mail_uid = 998 maildir_very_dirty_syncs = yes managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave namespace { list = children location = maildir:/home/vmail/%%u/mail:INDEX=/home/vmail/%u/mail/shared/%%u prefix = shared/%%u/ separator = / subscriptions = no type = shared } namespace inbox { inbox = yes location = maildir:/home/vmail/%u/mail prefix = separator = / type = private } passdb { args = /etc/dovecot/dovecot-ldap-passdb.conf.ext driver = ldap } passdb { args = /etc/dovecot/passwd.masterusers driver = passwd-file master = yes } plugin { acl = vfile acl_anyone = allow acl_shared_dict = file:/home/vmail/.shared-mailboxes sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } protocols = " imap lmtp sieve" service auth-worker { user = $default_internal_user } service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0666 user = postfix } unix_listener auth-userdb { group = vmail mode = 0777 user = vmail } } service imap-login { inet_listener imap { port = 143 } inet_listener imaps { port = 993 ssl = yes } } service imap-postlogin { executable = script-login /etc/dovecot/acl-groups.sh user = $default_internal_user } service imap { executable = imap imap-postlogin } service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0666 user = postfix } } service managesieve-login { inet_listener sieve { port = 4190 } } ssl_cert = </etc/easy-rsa/keys/dovecot.crt ssl_key = </etc/easy-rsa/keys/dovecot.key userdb { args = /etc/dovecot/dovecot-ldap-userdb.conf.ext driver = ldap } userdb { args = /etc/dovecot/dovecot-ldap-userdb-groups.conf.ext driver = ldap } protocol imap { imap_client_workarounds = delay-newmail mail_plugins = acl imap_acl } protocol lmtp { mail_plugins = acl sieve }

[Dovecot] how to calculate mail storage/traffic used
by Götz Reinicke - IT Koordinator 08 Nov '13

08 Nov '13

Hi, may be som mailserver admins on the list can give me som hint. Thats not dovecot related, but I know the knowledg here is enormous. We have to setup a server which gets a copy of all messages send and received by our mailserver as a 1:1 copy. Mails send to multiple recipients should be calculated and saved per user. (great if you usually have lost of mails send to groups of people.) So no dedublication should be used here. (e.g. save the message and refer the different recipients to it.) How can I calculate the current traffic in the best way to extrapolate the amount of space to be planed for the new server? We think to have a couples of days to be saved. Thanks for any hint or comment.

[Dovecot] Solr clusters
by Timo Sirainen 07 Nov '13

07 Nov '13

Hi all, Has anyone implemented larger Dovecot+Solr clusters and would be willing to give some details about how it works for you? My understanding about it so far is: - SolrCloud isn’t usable with Dovecot. Replication isn’t useful, because nobody wants to pay for double the disk space for indexes that could be regenerated anyway. The autosharding isn’t very useful also, because: I think the shard keys could be created in two possible ways: a) Mails would be entirely randomly distributed across the cluster. This would make updates efficient, because the writes would be fully distributed across all servers. But I think it would also make reads somewhat inefficient, since all the servers would have to be searched and the results combined. Also if a server is lost, there’s no easy way to reindex back the missing data, because it would contain a piece of pretty much all the users’ data. b) Shard keys could be created so that the same user would typically go only to 1-2 servers. It would be possible (at least in theory) to find a broken server’s list of users and reindex only their data, but I’m not sure if this method is any easier than the non-SolrCloud setup. - Without SolrCloud you’d then need to shard the data manually. This would be easy enough to do by just assigning different users to different shards. But at some point the index is going to become too large and you need to add more shards and move some existing users to them. To keep the search performance good during the move, I guess this could be done with a script that does: 1) reindex user to new shard, 2) update userdb to point to new shard, 3) delete user from old shard, 4) doveadm fts rescan the user to remove any mails already deleted during the reindexing. - It seems that Solr index shouldn’t grow above 200 GB or the performance will be getting too bad? I’ve seen this in a few web pages. So each server should likely be running multiple separate Solr instances (shards). - http://www.hathitrust.org/blogs/large-scale-search/scaling-large-scale-sear… recommends NFS (or I guess any kind of a shared filesystem), which does seem to make sense. Since Dovecot wants to get instantly updated search results after indexing, I think it’s probably better not to separate the indexing and searching servers. - Would be interesting to know what kind of hardware your Solr servers currently have, how well they’re performing and what are the bottlenecks? From the above URL it appears that disk I/O is first, but if there’s enough of that available then CPU usage is second. I’m not quite sure where most of the memory goes - caching? - I’m guessing users are doing relatively few searches compared to how many new emails are being indexed/deleted all the time?

[Dovecot] Postfix delivers mails to maildir and not to dovecot LDA for a virtual user
by Tru Pheenix 06 Nov '13

06 Nov '13

Hi I have been able to setup postfix and dovecot using postgres as the backend store with virtual user maps on Ubuntu 12.04 LTS Server. I have been following instructions from here: http://wiki2.dovecot.org/HowTo/DovecotPostgresql I haven't setup postfix to use saslauthd and PAM, instead I am using dovecot for SASL authentication. Rest of the table structures and query files are the same as from the wiki. SASL authentication works correctly for SMTP POP IMAP. I am able to send emails from a mail client such as Thunderbird with SASL authentication. However I am not able to receive emails for virtual users. I cannot figure out why. System users are getting their emails in the mail box correctly. Postfix fires the mailbox_command to hand over the mail to dovecot. This is how my *mail.log* looks when I send emails from an external domain: Nov 6 06:48:21 localhost postfix/smtpd[20053]: E075280C52: client= mail-ee0-f41.google.com[74.125.83.41] Nov 6 06:48:22 localhost postfix/cleanup[20064]: E075280C52: message-id=< CAJ+V0eCU891rSzSMVbcSy4zsRUk5GUp58b70Wv_WgZxLbKuyLw(a)mail.gmail.com> Nov 6 06:48:22 localhost postfix/qmgr[17492]: E075280C52: from=< me(a)gmail.com>, size=3124, nrcpt=1 (queue active) *Nov 6 06:48:22 localhost postfix/virtual[20066]: E075280C52: to=<someone(a)mydomain.com <someone(a)mydomain.com>>, relay=virtual, delay=0.85, delays=0.7/0.02/0/0.13, dsn=2.0.0, status=sent (delivered to maildir)* Nov 6 06:48:22 localhost postfix/qmgr[17492]: E075280C52: removed Nov 6 06:48:22 localhost postfix/smtpd[20053]: disconnect from mail-ee0-f41.google.com[74.125.83.41] Postfix seems to deliver the mail to maildir instead of the home directory of the virtual user.

Hi, imap_msgpart_crlf_seek() returns an error stream in case of problems in message_skip_virtual(). The original input stream is not being unreferenced, preventing destroy callbacks from being executed. Shouldn't we have an i_stream_unref(&input) here: src/lib-imap-storage/imap-msgpart.c: 398 if (message_skip_virtual(input, virtual_skip, &cr_skipped) < 0) { 399 errinput = i_stream_create_error(errno); 400 i_stream_set_name(errinput, i_stream_get_name(input)); 401 return errinput; 402 } ?

[Dovecot] 2.2.6 auth process crash using LMTP and LDAP on director.
by Olivier Girard 06 Nov '13

06 Nov '13

I'm upgrading my configuration to use director and lmtp for delivery. (doveconf -n at end of the mail). I use the same config for auth on mail backends and see no errors. My setup seem to work nicely but i have some auth process crashing when using lmtp protocol. Everything is working a sexpected then i've got 5-6 errors like this in logs and a crach of the auth process: dovecot: lmtp(47269): Error: passdb lookup(_mail_): Disconnected unexpectedly pid 47406 (auth), uid 143: exited on signal 11 Actually, i didn't configure to core dump. Do you think seting up lmtp protocol to static auth adding something like folow will be better for this problem? protocol lmtp { passdb { args = proxy=y nopassword=y driver = static } } Please note that my configuration is actually listening on inet fot LMTP but that the goal is to configure postfix on the same server and switch to socket, this expain the configuration of the service auth to provide a socket to postfix. Here is my director config: % doveconf -n # 2.2.6: /usr/local/etc/dovecot/dovecot.conf # OS: FreeBSD 8.4-RELEASE-p4 amd64 auth_cache_negative_ttl = 0 auth_cache_size = 16 M auth_mechanisms = plain login auth_verbose = yes auth_verbose_passwords = sha1 default_process_limit = 4000 director_mail_servers = 192.168.16.1 192.168.16.2 192.168.16.3 director_servers = 192.168.16.4 192.168.16.5 192.168.16.6 disable_plaintext_auth = no doveadm_port = 24245 info_log_path = syslog instance_name = director lmtp_proxy = yes mail_debug = yes managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave passdb { args = /usr/local/etc/dovecot/dovecot-ldap.conf.ext driver = ldap } plugin { mail_log_events = delete undelete expunge copy mailbox_delete mailbox_rename mail_log_fields = uid box msgid size } service anvil { client_limit = 12003 } service auth-worker { process_min_avail = 10 user = $default_internal_user } service auth { client_limit = 16000 unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0666 user = postfix } unix_listener auth-userdb { mode = 0666 user = $default_internal_user } user = $default_internal_user } service director { fifo_listener login/proxy-notify { mode = 0666 } inet_listener { address = 192.168.16.4 port = 9090 } unix_listener director-userdb { mode = 0600 } unix_listener login/director { mode = 0666 } } service doveadm { inet_listener { port = 24245 } } service imap-login { executable = imap-login director } service lmtp { inet_listener lmtp { address = * :: port = 24 } } service pop3-login { executable = pop3-login director } ssl_cert = </etc/ssl/cert/mail.univ-angers.fr.pem ssl_key = </etc/ssl/cert/mail.univ-angers.fr.key userdb { args = /usr/local/etc/dovecot/dovecot-ldap.conf.ext driver = ldap } protocol lmtp { auth_socket_path = director-userdb } protocol doveadm { auth_socket_path = director-userdb } local 192.168.16.0/24/24 { doveadm_password = mysecret } Last thing, in my config file, there is only one /24 on local network but this is another problem.

[Dovecot] increased core dumps with v2.2.7

Hi, After upgrading to v2.2.7 yesterday, I am starting to get a larger number of bugs occurring -- unfortunately I hadn't configured things to save core dumps (now done). But I am seeing things like: dovecot: imap(user(a)example.com): Fatal: master: service(imap): child 27931 killed with signal 11 (core dumped) kernel: [151706.763475] imap[4878]: segfault at 7fff53b0aff8 ip 00007fdc7ed65ece sp 00007fff53b0b000 error 6 in lib20_zlib_plugin.so[7fdc7ed61000+7000] dovecot: imap(user2(a)example.com): Fatal: master: service(imap): child 4870 killed with signal 11 (core dumped) As soon as I have more info., I'll let you know.

[Dovecot] Message parser loops on certain messages (e.g. with a trailing CR character)
by Tomasz Potega 05 Nov '13

05 Nov '13

Hi, dovecot's message parser enters an endless loop when fed with certain multipart messages with stray CR characters. parse_next_body_to_boundary() assumes the '\r' might be the beginning of a boundary line, reducing the block size by one: src/lib-mail/message-parser.c: 404 /* no linefeeds in this block. we can just skip it. */ 405 ret = 0; 406 if (block_r->data[block_r->size-1] == '\r') { 407 /* this may be the beginning of the \r\n--boundary */ 408 block_r->size--; 409 } For a block size of 1 (e.g. the trailing '\r' character), dovecot ends up processing zero-sized blocks, calling message_parser_read_more() without skipping the input stream: ... #6 0x00007f94f49374c7 in i_stream_read (stream=0xbe2fc8) at istream.c:167 #7 0x00007f94f49383d5 in i_stream_read_data (stream=0xbe2fc8, data_r=0x7fff2141d6b0, size_r=0x7fff2141d6b8, threshold=1) at istream.c:497 #8 0x00007f94f4918c2b in message_parser_read_more (ctx=0xbe7c10, block_r=0x7fff2141d6a0, full_r=0x7fff2141d667) at message-parser.c:128 #9 0x00007f94f491af67 in message_parser_parse_next_block (ctx=0xbe7c10, block_r=0x7fff2141d6a0) at message-parser.c:1012 #10 0x00007f94f491b2fb in message_parser_parse_body (ctx=0xbe7c10, hdr_callback=0x7f94f4c69a75 <parse_bodystructure_part_header>, context=0xbf0450) at message-parser.c:1075 #11 0x00007f94f4c6a876 in index_mail_parse_body (mail=0xbecd00, field=MAIL_CACHE_IMAP_BODYSTRUCTURE) at index-mail.c:895 #12 0x00007f94f4c6aedb in index_mail_parse_bodystructure (mail=0xbecd00, field=MAIL_CACHE_IMAP_BODYSTRUCTURE) at index-mail.c:1046 #13 0x00007f94f4c6b4a5 in index_mail_get_special (_mail=0xbecd00, field=MAIL_FETCH_IMAP_BODYSTRUCTURE, value_r=0x7fff2141d958) at index-mail.c:1170 #14 0x00007f94f4bfab53 in maildir_mail_get_special (_mail=0xbecd00, field=MAIL_FETCH_IMAP_BODYSTRUCTURE, value_r=0x7fff2141d958) at maildir-mail.c:570 #15 0x00007f94f4c36ea1 in mail_get_special (mail=0xbecd00, field=MAIL_FETCH_IMAP_BODYSTRUCTURE, value_r=0x7fff2141d958) at mail.c:269 #16 0x000000000041c5d7 in fetch_bodystructure (ctx=0xbd6a48, mail=0xbecd00, context=0x0) at imap-fetch.c:678 ... You will find a sample message attached to this mail. I have added a check to see if the parser is past the EOF (and omit reducing the block size then) as a band-aid fix, but this might call for a more elegant solution.

[Dovecot] Config problem: want SSL + local roundcube
by Rich 05 Nov '13

05 Nov '13

Hi, Have used dovecot for many years, happy that it worked well without me needing to do anything much! But since the upgrade from v1 to v2.1.7-7 I've come across some config probs. I want IMAP and to force TLS for all internet connections. However, I run RoundCube on the same server (over https) and this needs access too, but this doesn't need to be TLS because it's local anyway. The auto-config update script made some changes, it added the following to force SSL. service imap-login { inet_listener imap { port = 0 } } ssl = required But this seems to forbid the local roundcube service from logging in. Can anyone help me with my config? I had a stab, adding the following, but it didn't work. Was a complete guess anyway! remote 127.0.0.1 { ssl = no service imap-login { inet_listener imap { port = 143 } } } Here's my full config: # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-amd64 x86_64 Debian 7.2 ext3 auth_default_realm = artfulrobot.com log_timestamp = "%Y-%m-%d %H:%M:%S " mail_location = maildir:/home/virtual/%d/%n mail_privileged_group = mail passdb { args = username_format=%n /etc/exim4/virtual_domains/%d/passwords driver = passwd-file } protocols = imap service auth { unix_listener auth-client { group = Debian-exim mode = 0660 } user = root } service imap-login { inet_listener imap { port = 0 } } ssl = required ssl_cert = </etc/ssl/certs/mail.artfulrobot.com-with-chain.crt ssl_key = </etc/ssl/private/mail.artfulrobot.com.key userdb { args = uid=1001 gid=1001 driver = static } userdb { driver = passwd } Thanks, Rich

[Dovecot] [bug] ssl-params hangs when FIPS is enabled
by Michal Hlavinka 05 Nov '13

05 Nov '13

Hi, we found a bug in ssl-params. It calls openssl DH generator for 512 and 1024 bits, but in FIPS mode, openssl won't generate anything for less than 1024, so it fails with: error:0506A06E:Diffie-Hellman routines:DH_BUILTIN_GENPARAMS:key size too small but when DH generator fails, ssl-params hangs forever in io_loop_run: __epoll_wait_nocancel() io_loop_handler_run(..) at ioloop-epoll.c:176 io_loop_run(..) at ioloop.c:406 master_service_run(..) at master-service.c:566 main(..) at main.c:156 Getting system in FIPS mode can be a little tricky, but DH_generator simulated failure can do the trick. Just change ssl-params/ssl-params-openssl.c:generate_dh_paramaters:39 - if (dh == NULL) { + if (1 || dh == NULL) { and when you run ssl-params (with no ssl-parameters.dat), it hangs. Let me know if you need more information. Regards, Michal Hlavinka

[Dovecot] Issue with postfix not handing over e-mails to dovecot
by Tru Pheenix 05 Nov '13

05 Nov '13

Hello! I have installed postfix with dovecot and postgresql. I have set up SASL authentication for postfix and dovecot and been able to test them successfully. I am able to send sasl authenticated emails through smtpd on postfix using a mail client like Thunderbird. However, now I am unable to receive any e-mails. When I respond to the emails, I get a not delivered failure from postfix. I cannot figure out why postfix is not handing over the e-mails to dovecot. So here are some links to follow: posftconf output: https://gist.github.com/anonymous/7318863 doveconf output: https://gist.github.com/anonymous/7318896 tail -f /var/log/mail.* output (when receiving mail): https://gist.github.com/anonymous/7318945 Any help to solve this would be highly appreciated.

This is a great idea. In my case I think I will get away with a five minute cron job since the pickup latency should be manageable to the users and there is less to install. But I like in principle the idea of an immediate, fs-driven trigger, which would probably use fewer CPU cycles in the aggregate. > [...]all my users moved messages into spam/yes, > but copied them into spam/no Unfortunately I can't rely on users getting this right, much less understanding the difference between copy and move semantics. And I'm probably not going to be able to upgrade my users. Thanks for your advice! -d

[Dovecot] Is it safe to manipulate Maildir files directly?
by David Henkel-Wallace 05 Nov '13

05 Nov '13

Dovecoters, is it safe to manipulate files in Maildir/xxx directly or will Dovecot become unstable if I don't make these changes by talking to Dovecot and having it make the changes? (I'm running 2.1.7 under Wheezy, IMAP only) My specific application: I am running spamassassin and would like users to be able to submit spam (and ham) directly by moving it into special folders. A cron job can then find it and take action: feed spam messages to the bayesian trainer and then delete them; feed ham messages to the trainer and then move them into ~/Maildir/cur/ Having the cron job find the messages and train spamassassin is no problem. The question is how to move the messages. Is it safe to simply rename the files from my cron job? The dovecot wiki implies that dovecot will notice a change in mtime and deal with it safely. Am I reading this correctly? Changing a message flags (i.e. name) and/or directory will change mtime. If I have to go through to Dovecot I am afraid I'd need the user's credentials, which is not appropriate. Thanks! -d

http://dovecot.org/releases/2.2/dovecot-2.2.7.tar.gz http://dovecot.org/releases/2.2/dovecot-2.2.7.tar.gz.sig * Some usage of passdb checkpassword could have been exploitable by local users. You may need to modify your setup to keep it working. See http://wiki2.dovecot.org/AuthDatabase/CheckPassword#Security + auth: Added ability to truncate values logged by auth_verbose_passwords (see 10-logging.conf comment) + mdbox: Added "mdbox_deleted" storage, which can be used to access messages with refcount=0. For example: doveadm import mdbox_deleted:~/mdbox "" mailbox inbox subject oops + ssl-params: Added ssl_dh_parameters_length setting. - master process was doing a hostname.domain lookup for each created process, which may have caused a lot of unnecessary DNS lookups. - dsync: Syncing over 100 messages at once caused problems in some situations, causing messages to get new UIDs. - fts-solr: Different Solr hosts for different users didn't work.

[Dovecot] Shared mailbox help needed
by Alex Ferrara 04 Nov '13

04 Nov '13

Hi everyone, I am in the middle of a migration from Cyrus 2.4 to Dovecot 2.1.7, and I have everything mostly working. I set up Dovecot to authenticate against Active Directory (Samba4) using PAM and SSSD, and have also used the fantastic cyrus2dovecot perl script to do a test migration of all our mail, and that is now working flawlessly. I have the issue of shared IMAP accounts to deal with, and I am a little stuck. I see that Dovecot is very flexible, and I think I am getting stuck in this flexibility. I thought that if I explain what I am trying to achieve, someone might point me in the right direction. In the Cyrus regime, we have several imap accounts that are shared with a group of people. These groups are actual unix groups that actual unix users are a member of. If we want a person to access a mailbox, we add them to the group and then at next login, it pops up in Thunderbird automatically. SSSD does, from what I can tell, a decent job of binding to AD and mapping AD users to unix users, but since not all of the users have an NIS uid in AD, I decided to use a static mapping. This might have been the wrong decision, I am not sure. userdb { driver = static args = uid=900 gid=900 home=/mnt/mail/%u allow_all_users=yes } It probably isn't important at this stage, but the mail spool is stored on an NFS server and the indexes are stored locally. Thanks in advance, Alex Ferrara Director Receptive IT Solutions

Re: [Dovecot] Doveadm with a 2nd Instance

While testing some more I found out something else. I have an alias set for doveadm so it was running with sudo and that ended up being part of the issue. If doveadm is run as a regular user then the problem goes away [user@server ~]$ doveadm -i Director log find Debug: /home/user/apps/logs/director/director_debug.log Info: /home/user/apps/logs/director/director_info.log Warning: /home/user/apps/logs/director/director.log Error: /home/user/apps/logs/director/director.log Fatal: /home/user/apps/logs/director/director.log [user@server ~]$ sudo doveadm -i Director log find Debug: /home/user/apps/logs/dovecot_debug.log Info: /home/user/apps/logs/dovecot_info.log Warning: /home/user/apps/logs/dovecot.log Error: /home/user/apps/logs/dovecot.log Fatal: /home/user/apps/logs/dovecot.log Also if I run "sudo doveadm stop" to stop the main instance, I now have the ability to use the -i Director using sudo. Unfortunately this makes it difficult to manage two instances. Does anyone have an idea of getting this to work with sudo? Chris

[Dovecot] Encryption solution for messages at rest
by Douglas Mortensen 03 Nov '13

03 Nov '13

Hi, We have clients with various security & compliance requirements. Although not required, it would be ideal to have messages encrypted at rest. We already use SSL/TLS to secure the transmission of most email. However, it would be nice to have them encrypted sitting on our server. Is anyone doing this? I think that ideally, rather than full-disk encryption, we should use an encryption that encrypts the actual email messages as they sit on our file system. This way even if we ever had our server breached by an attacker, they wouldn't be able to do anything with the messages. However, this would also mean that if the attacker can't decrypt the files, than dovecot and postfix still would need to. This means that the encryption key would need to be available to the dovecot deamon. We'd either need to have it in a file that is restricted to access only by dovecot (less secure), or use an encryption passphrase for the certificate which would have to be typed in manually each time that dovecot starts or restarts (more secure, but also more work and possibility of disruption because the server can't restart gracefully without a human being having to be present [although I don't think we have issues with unexpected restarts anyway]). Is anyone doing anything like this with dovecot? Thanks!! - Doug Mortensen Network Consultant Impala Networks Inc CCNA, MCSA, Security+, A+ Linux+, Network+, Server+ A.A.S.

[Dovecot] Assertion error in Dovecot 2.2.6
by Mark Sapiro 03 Nov '13

03 Nov '13

Background. A while back I upgraded my phone to one currently using Android 4.1.2 and K9 mail 4.409. This phone/MUA combination seems at times to go crazy making IMAP connections. At first, I had mail_max_userip_connections = 30 (my largest imap account has 19 folders). The issue I had at that time was multiple errors like Oct 14 17:45:16 sbh16 dovecot: imap-login: Maximum number of connections from user+IP exceeded (mail_max_userip_connections=30): user=<xxx>, method=PLAIN, rip=xx.xx.xx.xx, lip=xx.xx.xx.xx, TLS, session=<c63x5bzowQBi0uQR> I then set mail_max_userip_connections = 50 This greatly reduced but didn't completely eliminate these messages, but then I would see multiple Oct 31 16:13:40 sbh16 dovecot: master: Warning: service(imap-login): process_limit (100) reached, client connections are being dropped and Oct 31 16:13:40 sbh16 dovecot: imap-login: Disconnected: Connection queue full (no auth attempts in 4 secs): user=<>, rip=xx.xx.xx.xx, lip=xx.xx.xx.xx, TLS handshaking, session=<s26xmRHqVQBi0uQR> followed finally by Oct 31 16:13:40 sbh16 dovecot: imap-login: Panic: file client-common.c: line 190 (client_destroy): assertion failed: (!client->authenticating) Oct 31 16:13:40 sbh16 dovecot: auth: Warning: auth client 19669 disconnected with 1 pending requests: EOF Oct 31 16:13:40 sbh16 dovecot: imap-login: Fatal: master: service(imap-login): child 19669 killed with signal 6 (core not dumped - add -D parameter to service imap-login { executable } I then set default_process_limit = 200, and things seem to have settled down, but I thought the panic should be reported.

[Dovecot] METADATA for v2.2.7
by Timo Sirainen 02 Nov '13

02 Nov '13

In case someone wants to try: http://hg.dovecot.org/dovecot-2.2/rev/0a08efeb3f40 The commit message lists the TODO. So for example if you want to enable it just for webmail (because quota limits aren’t there yet): mail_attribute_dict = file:%h/dovecot-attributes local 10.0.0.0/24 { imap_metadata = yes } Compared to the old metadata plugin, there are some improvements: - Uses lib-storage attributes internally, which means: - dsync replicates METADATA - it will be easy to add support for untagged METADATA notifications to clients when they change - SETMETADATA atomically either updates all or none of the changes Things that work in the METADATA code, but still require lib-dict changes to work properly: - Values with unlimited sizes - Values with binary data (NULs)

[Dovecot] DH parameter length too small?
by Jörg Lübbert 02 Nov '13

02 Nov '13

Hello, from my understanding, using 1024bit DH parameters results in a not sufficiently secure key exchange for DH(E). Therefore I think it would be advisable to have parameters of at least 2048bit . In fact, I would see a great benefit in chosing parameter length arbitrarily. I also do not see the benefit of parameter regeneration. What were the design goals here? Thanks, Jörg Lübbert

[Dovecot] Pre imap-session scripting
by azurIt 02 Nov '13

02 Nov '13

Hi, is it possible to run a script right after the IMAP/POP3 session was started? I know about post-login scripting but this is probably not what i'm looking for. I need to run a script which will know PID of process running IMAP session (so it must be already started). Thank you. azur

[Dovecot] Broken files?
by LuKreme 02 Nov '13

02 Nov '13

Getting a lot of these error for two specific mailboxes. They repeat many times a day, usually within less than 5 minutes. mail dovecot: imap(kremels): Error: Broken file /home/kremels/Maildir/.zz.x-tech.2010/dovecot-uidlist line 2: Invalid extended fields: : $ cat .zz.x-tech.2010/dovecot-uidlist 3 V1263241007 N56581 G11fe2118db236952f984010021d1a38d OI tried deleting the files that generated the errors, but they were recreated and the errors returned. (I’m using dovecot2 and Maildir) -- Death was familiar with the concept of the eternal, ever-renewed hero, the champion with a thousand faces. He'd refrained from commenting.
