[Dovecot] Imap user via proxy with starttls - how to rawlogs on proxy ?
by askforstatus 02 May '14

02 May '14

Hello, Is there any way to log user imap dialog with starttls when going via dovecot acting as imap proxy ? My intention is to log each and every user command similar to rawlogs feature. As per my current imap proxy config pre-login working like a charm but post-login is not possible due as i think the nature of proxy feature. Any idea ? Regards -- View this message in context: http://dovecot.2317879.n4.nabble.com/Imap-user-via-proxy-with-starttls-how-… Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] Not backing up cache files
by Jesus Cea 02 May '14

02 May '14

I am using mdbox for dovecot storage. I wonder if I could skip "dovecot.index.cache" files and, in general, "*.cache" files when doing mail backup. Those files are big and change frequently. What I feel from reading documentation [1][2] is that they could be dropped in the backups, to be recreated on the fly if needed. But I would like expert confirmation.

[Dovecot] BUG dovecot and nginx
by Tobias Oetiker 02 May '14

02 May '14

we have setup a two level proxy configuration for our zimbra server: [ dovecot 2.2.12 (imap proxy mode) ] V [ nginx (imap proxy mode) ] V [ zimbra imap server] and it does not work ... after tying a login, the connection just hangs and ends after 30 seconds with a timeout. - if I try again rightaway in the same dovecot connection, the login goes though without trouble. - looking at this with tshark I can see that on the second attempt, there is no capabilities query, dovecot just goes ahead and connects. if we drop nginx from the setup all is well also (login works directly as expected) - investigating the traffic differences between the setups with and without nginx, we find that for some reason dovecot does not react to the capabily answer from nginx. while it seems to happily accept the same answer when it is coming from zimbra directly. - the only difference I can see on the wire is that nginx is much quicker (2.5ms) in responding than the zimbra (25ms) server and that the position of the STARTTLS and SASL=PLAIN capabilities in the capability answer differs between the two. any ideas ? cheers tobi -- Tobi Oetiker, OETIKER+PARTNER AG, Aarweg 15 CH-4600 Olten, Switzerland www.oetiker.ch tobi(a)oetiker.ch +41 62 775 9902 *** We are hiring IT staff: www.oetiker.ch/jobs ***

[Dovecot] Rebuilding message guid in sdbox
by Renaud Allard 02 May '14

02 May '14

Hello, I am running dovecot 2.2.12 Current mail storage is sdbox and I am trying to compress all emails, which works fine, except for a few old mailboxes. If I run the following dsync command "dsync -u flea -o "mail_plugins=zlib" mirror maildir:~/ndbox" It fails with: dsync(flea): Error: Exporting mailbox INBOX failed: Backend doesn't support GUIDs, sync with header hashes instead Doing "doveadm dump flea/dbox/mailboxes/INBOX/dbox-Mails/dovecot.index" reveals that there are very old mails (about 5 years ago) without any guid like that one: RECORD: seq=1, uid=1560, flags=0x00 - ext 1 modseq : 16043 (ab3e000000000000) - ext 3 cache : 396 (8c010000) - cache offset=396 size=20, prev_offset = 0 - guid: So, my question is: is there a way to force dovecot to assign a guid to those messages? Best Regards

[Dovecot] Dovecot Director and MasterUsers
by Daniel Parthey 02 May '14

02 May '14

Hi, the Dovecot Director determines the backend host in some way by hashing the username: http://wiki2.dovecot.org/Director For normal logins username(a)example.org, the director always gets the same hash for the same username and ensures that the login is always proxied to the same backend. But what about MasterUsers in combination with Dovecot Director? http://wiki2.dovecot.org/Authentication/MasterUsers Which configuration directives should be used to make sure that logins username@example.org*masteruser1@example.org username@example.org*masteruser2@example.org username@example.org*masteruser3@example.org go to the same mailbox backend, in order to avoid NFS caching conflicts for mailbox username(a)example.org which should always reside on the same NFS client? Is the master user cut off from behind the master_user_separator? How is the director hash exactly calculated? Can the director hashing algorithm be configured in some way? Regards Daniel

Hi everybody, I'm using dovecot-2.2.11 on NetBSD. After a kernel upgrade, while using the same dovecot binaries (they were working perfectly until today), I'm experiencing this error (more log at the end of my email): BUG: Authentication client sent unknown handshake command: REQUEST?227672066?18807?2?c717631d60216b2e9ec57a2fa69674b8?session_pid=16343?...

login_log_format = %$: %s login_log_format_elements = user=<%u> method=%m rip=%r lip=%l mpid=%e %c session=<%{session}> These are the defaults, at least on a Fedora system. According to http://wiki2.dovecot.org/Variables, this should record for user@REALM when seeing the following Apr 30 18:08:40 TeaSet dovecot: auth: Debug: auth(user,...,<JhKid0v4bAAKAQG6>): username changed user -> user@REALM. If I wanted just user, user=<%u> should be changed to user=<%orig_user>. However, I only get user not user@REALME in imap-login log lines. I wouldn't mind this, but auth_username_format cannot be used in passed{} and I haven't been able to get pam_krb5 to uppercase the realm for it alone. (Everything else depends on it being lowercase.) I can make this work by just passing the user name part of username in the client, but then imap-login still doesn't have the required information for the same reason. Anyone have any suggestions? Thank you, Trever

[Dovecot] Dovecot 2.0.16 question...
by Farokh Irani 30 Apr '14

30 Apr '14

I'm running Dovecot 2.0.16 on OS X Server 10.7.5 and I've got a problem with IMAP searches. There are a couple of accounts that are unable to search using an IMAP search, but I can't seem to find anything wrong. Any pointers on what I can do? Is there a search index file that I can delete to force a rebuild, or a script or app that will do that? I tried to use update-fts-index.pl, but to no avail. Thanks!

[Dovecot] doveadm import : Error creating new mailbox
by Administrator BCS 29 Apr '14

29 Apr '14

Hello, I'm new to dovecot. I managed to set up a system running dovecot/mysql/postfix/postfixadmin with a virtual maildir setup on Ubuntu 12.04 I can add and remove users, send and receive mail, create folders, move mail between them etc so all ok. Now trying to manually import some mbox files from the old server into dovecot. Copied a mbox file to the new system, converted it to Maildir with mb2md resulting in a directory containing the new, cur en tmp. Looks ok, old email messages are all there. When importing this folder using doveadm import it fails with the message: Error: Couldn't create mailbox maildir:/home/vmail/bezoekerscentrumsonsbeek.nl/techniek/.INBOX: Invalid mailbox name What am I doing wrong?

[Dovecot] Why does it appear that dovecot is deleting messages after migration?
by Bill Eccles 28 Apr '14

28 Apr '14

Hi, y'all, long-time Mac OS X Server user Bill here with a thorny question for the mailing list since nobody at discussions.apple.com can quite put their finger on the answer. While well-aquainted with other aspects of Server, Dovecot is a bit of a mystery still to me. So here it goes: Background I'm struggling to migrate from MacOS X 10.6 to 10.9. I tried twice using the "live server in target disk mode" method, but after things went horribly awry (meaning I was left with no working services on the new server), I gave up on that and have been working to slowly bring services over, one at a time. I've got both Dovecot and PostFix accepting connections from my test machine, and I am able to connect with IMAP to the new server. What I Do... First, I turn both mail servers off. Then I tar up the /var/spool/imap/dovecot/mail directory on the old server, move it to the new server, untar it in /Library/Server/Mail/Data/ (where it belongs), and change ownership to _dovecot:mail, all per many other suggestions found in the Apple forums. (All files appear to be in maildir format, that I can tell.) I then turn the mail service back on on the new server. What Dovecot Does... (or appears to do) If I quickly connect to the new server with my IMAP client (MacOS X Mail.app) and create a "fresh user" in Mail.app, message folders appear correctly. But it's only a matter of time before Dovecot, or something, runs "doveadm index -u (usernames) (mailboxes)" on all of the mailboxes. As it does, it deletes thousands of messages, leaving, for example, the same 17 in INBOX and 3695 in "Deleted Items Archive". And 0 in others, and other seemingly-random numbers of messages in still yet others. I can watch it marching through the mailboxes, one at a time, if I "ps -ax" enough times. What I've Done to Counteract This... Nothing I've done so far has been able to do anything about it. Re-untar the archive, and it just does it all again. Try using dsync, and it just deletes the messages from the un-tar'd archive. In other words, there are thousands of messages in the archive which don't seem to meet Dovecot's requirement for being in that particular folder, so it deletes them. The "cur" directory in a mailbox directory may start out with >21000 messages in it, but when it's done, it'll have deleted the same messages from "cur" every time, leaving me with a fraction of what I started out with. I even used the 65-migrate_mailboxes.pl script (supplied as part of OS X 10.9 Server), and the same thing happens. (The migrate script does a lot more than just what I've noted above, but most of what it does is responsible for settings and configuration migration. Very little of the script is responsible for moving the data, and that part of the script ends up being a bunch of "cp" followed by a "chown"--essentially what I'm doing.) The Questions What is going on? Failing a fix, am I trying to migrate the wrong way? Is there a better way? Random Thoughts and Observations I've changed hostnames. The old one was shr-xs.mydomain.net, and the new one is shr-mini.mydomain.net. Is it unhappy with that for some reason? In one of the directories where messages are deleted, there were a zillion files named like this: 1396718896.M324523P43630.shr-xs.mydomain.net,S=1209,W=1238:2,Sac There were also a bunch of files named like this: 1211416234.cyrus.457,S=893:2,Sac When it's all said and done, and Dovecot has done its thing, care to guess which ones are left? Only these: 1211416234.cyrus.457,S=893:2,Sac Just to see if I could influence which files get deleted, I deleted all of the dovecot* files in the mailbox directory. And Dovecot recreated them faithfully, but still deleted all but the ones which said "cyrus" in the filenames. I changed the hostname to match shr-xs.mydomain.net, and that doesn't seem to have affected things a bit, though I don't have enough data to support that I really succeeded in changing the hostname for all services (specifically for Dovecot). Is Dovecot really filtering out messages that just don't seem to "belong" in the folder? Thanks, y'all. I've puzzled on this one for about eight hours and it now hurts my brain. I hope somebody else has an answer sans brain hurts.

[Dovecot] Incompatibility Thunderbirds Auth Mech TLS-Certificate <-> Dovecot
by Christian Felsing 25 Apr '14

25 Apr '14

Hello, it seems there there is an issue regarding "TLS-Certtificate" authentication in Thunderbird and Dovecot. Obviously client certificate is recognized by Dovecot: Apr 25 14:29:01 dovecot dovecot: imap-login: Valid certificate: /emailAddress=christian.felsing(a)example.net/CN=Christian Felsing (Test)/OU=CF Certificates/O=example.net/C=DE AFAIK Dovecot always requires IMAP login, even in "static" passdb config. Static means arbitrary password is ok, but not "no login" I hope, I am wrong, following log entry gave a hint, what Thunderbird does or more precisely - not do: Apr 25 14:29:01 dovecot dovecot: imap-login: Disconnected (no auth attempts in 5 secs): user=<>, rip=192.168.1.99, lip=192.168.42.1, TLS, session=<3+1THN33NQBtWq5D> Dovecot wants an IMAP login, but Thunderbird does not so. I am not sure if that is a bug (or feature) of Dovecot or Thunderbird. Thunderbird does several strange things on client certificates: 1st) If Dovecot is configured to request a client certificate and Thunderbird is configured to use plain text auth, Thunderbird offers a client certificate and login succeeds as configured in Dovecot. Unfortunately Thunderbird uses same certificate for all configured accounts to that host. Very bad if Dovecot reads username from certificate attributes. 2nd) If Dovecot is configured to request a client certificate and Thunderbird is configured to use TLS-Certificate, Thunderbird also offers a client certificate, but Dovecot requests login from Thunderbird. That fails, because Thunderbird assumes TLS-Certificate is enough for successful log. If it is true that Dovecot is not compatible to Thunderbirds way of TLS-Certificate Authentication, I consider to set up a proxy, which supports that way. May be Nginx would be a solution, it supports IMAP and LUA module plus some LUA code will fake the authentication. This is an ugly hack so I would like to avoid that, if anybody has a better solution. Thunderbird is a very widespread IMAP client so it should not be ignored. best regards Christian ---Dovecot config--- # /opt/dovecot/bin/doveconf -n # 2.2.12: /opt/dovecot/etc/dovecot-cert/dovecot.conf # OS: Linux 3.2.0-4-amd64 x86_64 Debian 7.4 auth_debug = yes auth_debug_passwords = yes auth_master_user_separator = * auth_ssl_require_client_cert = yes auth_ssl_username_from_cert = yes auth_username_chars = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@#" auth_username_translation = "@#" base_dir = /var/run/dovecot-cert first_valid_uid = 124 last_valid_uid = 124 listen = 192.168.42.1 log_timestamp = %Y-%m-%d %H:%M:%S login_greeting = example.net imap4/pop3 (cert only) ready. mail_gid = 124 mail_location = maildir:~/Maildir mail_privileged_group = vmail mail_uid = 124 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 imapflags notify namespace { list = children location = maildir:%%h/Maildir:INDEX=~/Maildir/shared/%%u prefix = shared/%%u/ separator = / subscriptions = no type = shared } namespace inbox { inbox = yes list = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = separator = / type = private } passdb { args = password=test driver = static } plugin { acl = vfile:/etc/dovecot/global-acls:cache_secs=300 acl_shared_dict = file:/var/lib/dovecot/shared-mailboxes autocreate = Trash autocreate2 = Drafts autosubscribe = Trash autosubscribe2 = Drafts quota = maildir:User quota quota_rule = *:storage=500M quota_rule2 = Trash:storage=+100M quota_warning = storage=95%% quota-warning 95 %u quota_warning2 = storage=80%% quota-warning 80 %u recipient_delimiter = + sieve = ~/.dovecot.sieve sieve_dir = ~/sieve sieve_extensions = +notify +imapflags } protocols = imap pop3 lmtp sieve service anvil { client_limit = 4000 } service auth-worker { group = vmail } service auth { client_limit = 8000 unix_listener auth-master { group = vmail mode = 0660 user = vmail } unix_listener auth-userdb { group = vmail mode = 0660 user = dovecot } user = root } service imap-login { inet_listener imap { port = 143 } inet_listener imaps { port = 993 ssl = yes } process_limit = 1024 } service imap-postlogin { executable = script-login /opt/cfbin/lastlogin.sh } service imap { executable = imap imap-postlogin } service managesieve-login { inet_listener sieve { port = 4190 } inet_listener sieve_deprecated { port = 2000 } } service pop3-login { inet_listener pop3 { port = 110 } inet_listener pop3s { port = 995 ssl = yes } process_limit = 1024 } service pop3-postlogin { executable = script-login /opt/cfbin/lastlogin.sh } service pop3 { executable = pop3 pop3-postlogin } service quota-warning { executable = script /opt/cfbin/quota-warning.sh user = vmail } ssl_ca = </opt/dovecot/etc/dovecot/client-ca.pem ssl_cert = </opt/dovecot/etc/dovecot/example.net.pem ssl_cipher_list = kEECDH:kEDH:AESGCM:ALL:+3DES:!RC4:!LOW:!EXP:!MD5:!aNULL:!eNULL ssl_dh_parameters_length = 4096 ssl_key = </opt/dovecot/etc/dovecot/example.net.key ssl_prefer_server_ciphers = yes ssl_verify_client_cert = yes verbose_ssl = yes protocol imap { imap_client_workarounds = tb-extra-mailbox-sep mail_max_userip_connections = 20 mail_plugins = quota imap_quota acl imap_acl } protocol sieve { managesieve_logout_format = bytes ( in=%i : out=%o ) } protocol pop3 { mail_plugins = quota pop3_uidl_format = %08Xu%08Xv }

[Dovecot] separating logs by port
by Hanno Böck 25 Apr '14

25 Apr '14

Hi, I wanted to ask if there's an easy way to log the port in dovecot. The background is that, as everyone's probably aware, pop3/imap usually listen on two ports (110/995 for pop3, 143/993 for imap). One port is the "classic" port that allows unencrypted and STARTTLS connections, the other is the legacy SSL port that allows TLS only connections. The legacy SSL ports are considered deprecated and I'd like to know if I can deprecate them on my severs. Therefore I'd like to know how many users use them, but at the moment I can't see which port my users use. I haven't found an easy way to detect that. The easiest thing would be if there'd be a way to add the port number to the pop3-login/imap-login lines in the log files. Any way to do that? cu, -- Hanno Böck http://hboeck.de/ mail/jabber: hanno(a)hboeck.de GPG: BBB51E42

[Dovecot] Multiple Instances Of Dovecot On One Messagebase
by Christian Felsing 25 Apr '14

25 Apr '14

Hello, I would like to run multiple instances of Dovecot with same message base (maildir format) Will this set up work or would that destroy message base? Intention is to offer different authentication methods to users, username/password and client certificates. Those instances should run on different IP addresses which is supported by Dovecot. Unfortunately Dovecot does not allow different auth configs in "local <ip> {}" sections. best regards Christian

My old mail server used 2.x dovecot version. you post very little information: 1) how are the messages storred on the old server, which storage backend do you use, maybe Maildir? 2) the storage backend on the new server? 3) do you care about the message UIDs? 4) How many users do you have (approx.) and can you access the user's mailboxes via IMAP, e.g. using a master user or do you know their password or can you switch to a known password during migration of one particular user? 5) Did you've changed namespaces? - From your first post I figure that the basic mail server functionality of the new server is working, most importantly login, message delivery and retrieval. > -----Original Message----- From: Steffen Kaiser > Sent: Thursday, April 10, 2014 6:14 AM > To: K.

[Dovecot] Regarding Quota
by Joy 24 Apr '14

24 Apr '14

Dear All, One of my user is using sieve to make a copy of incoming mail in another folder all is working file. I have seen that he is using 15GB out of 20GB space of his mailbox, while calculating the same using du command returns only 9.5 GB. I am not facing this issue with any of other user. Is there something going wrong or misconfiguration causing this.

[Dovecot] Help implementing username_format in auth PAM driver
by lee＠trager.us 24 Apr '14

24 Apr '14

While configuring my server with dovecot I noticed that the PAM authentication driver does not support the username_format option as does the password file driver. This didn't seem too hard to implement so I through together a patch. As you can see in the attached patch I only modify the username sent to PAM. Despit doing this I run into the domain lost issue(http://wiki2.dovecot.org/DomainLost). This prevents me from using the domain name in my mail_location config string. What I don't understand is why does changing the username string sent to PAM for authentication trigger this issue? Shouldn't dovecot continue to use the client supplied username as I am *not* changing it anywhere in my config? Thanks, Lee

You know best whether you want to take the risk of compromising passwords on your system (including compromised accounts using for spamming and blowing your mail reputation to smithereens), but I don't know whether your customers do. They may think they are only risking their Email, but it can be leveraged to also gain access to other authentication systems e.g. "Forgot password" feature. You can suggest the installation of a SSL proxy for those holdouts that won't switch mail readers (stunnel even has support down to Win98). https://www.stunnel.org/ports.html These days, cleartext passwords over the network is just begging to be compromised.

Re: [Dovecot] ImapTest utility not compiling

* Found my error. I moved the dovecot source code after compiling it. Didn’t realize there were embedded/absolute URLS within the dovecot source tree.

I think there’s a problem in the imapTest utility? Copy/pasted compile output and attached. The gist of the problem seems to be that imaptest can’t find the dovecot headers and libraries (configure script was executed like this: ./configure --with-dovecot=/usr/src/dovecot-20140420 checkpoint.c:3:17: error: lib.h: No such file or directory checkpoint.c:4:17: error: str.h: No such file or directory <and many more> Based on these errors I believe there’s a compatibility problem between the current imapTest utility and dovecot.

[Dovecot] How to bring dovecot to using a slightly modified passwd file

Hello all, I am trying to use a setup where domains have separate passwd files with a slightly different layout. Is there a way to tell dovecot that a passwd file contains everything it looks for but on different positions inside the passwd file line? Standard passwd: USERNAME:PASSWD:UID:GID:HOME:extras different layout: USERNAME:PASSWD:extras:UID:GID:HOME Or do I have to patch the source, and where if necessary? Thanks for your help. -- Regards, Stephan

[Dovecot] Allowing non-SSL connections only for certain Password Databases
by Dan Pollock 23 Apr '14

23 Apr '14

I'm trying to set up my system (using Dovecot 2.0.9) so that certain Password Databases are available over pop3 and imap and others are available over pop3s and imaps. In particular, I would like users to be able to connect without SSL to accounts set up in vpopmail, but to require SSL for system accounts. Is there a way to set "disable_plaintext_auth" to different values for different Password Databases? Is there another way to do it? Thank you, Dan

For users using system accounts, it's important that passwords are protected (as they can use that password to log in to things other than email). It's not as critical to keep virtual mailboxes on vpopmail encrypted, as those accounts only have access to email. Dan

[Dovecot] Shared mailboxes not working with . dot namespace separator - values truncated in SQL
by Frantisek Kucera 23 Apr '14

23 Apr '14

Hello, I have Dovecot configured for multiple domains (usernames are user(a)domain.tld) and I wanted to enable shared mailboxes. But there is some problem - if I share a folder, other user can't see it. In the log I foud: > Apr 22 19:21:02 veverka dovecot: imap(user(a)veverka.tld): Error: Couldn't create namespace 'shared.' for user petr: userdb didn't return a home directory, but location used it (%h): maildir:%h/Maildir:INDEX=~/Maildir/shared/%%u > Apr 22 19:21:02 veverka dovecot: imap(user(a)veverka.tld): Error: Couldn't create namespace 'shared.' for user emclient@veverka: userdb didn't return a home directory, but location used it (%h): maildir:%h/Maildir:INDEX=~/Maildir/shared/%%u Which is weird because the user name is "petr.surname" not only "petr" and the domain is "veverka.tld" not only "veverka". So I turned on SQL logging on my PostgreSQL and saw that Dovecot executes these queries: > 2014-04-22 19:21:02 CEST LOG: statement: SELECT * FROM dovecot_uzivatel WHERE login = 'petr' AND domena = '' > 2014-04-22 19:21:02 CEST LOG: statement: SELECT * FROM dovecot_uzivatel WHERE login = 'emclient' AND domena = 'veverka' The first username was "petr.surname(a)veverka.tld" and the second one was "emclient(a)veverka.tld" so it seems that it was truncated right after first "." dot and I afraid that this is a bug. Then it is obvious that Dovecot can't find the home directory and complains in log (as mentioned above). I found workaround – I had "." configured as namespace separator so I reconfigured it to "/" slash and now mailbox sharing works! But I think that it should work also with "." dot separator and the values should not be truncated in SQL queries. I tried also using '%u' in my SQL and its value was also truncated. Values in "dovecot-acl" a "shared-mailboxes" files seem to be ok. BTW: I have also another server with only one domain and simple user names (no dots) and there the mailbox sharing works – but now it seems that it works only accidentally. This might lead to hardly debuggable problems if someone has usernames with and without dots – mailbox sharing will work for some users but for some not. My old configuration: > password_query = SELECT * FROM dovecot_heslo WHERE login = '%n' AND domena = '%d' > user_query = SELECT * FROM dovecot_uzivatel WHERE login = '%n' AND domena = '%d' > iterate_query = SELECT login AS username, domena AS domain FROM dovecot_uzivatel > namespace { > type = shared > separator = . > prefix = shared.%%u. > location = maildir:%h/Maildir:INDEX=~/Maildir/shared/%%u > subscriptions = yes > list = children > } Had to be reconfigured to: > separator = / > prefix = shared/%%u/ Used version: > # dovecot --version > 2.1.7 > # uname -a > Linux veverka 3.11.0-19-generic #33-Ubuntu SMP Tue Mar 11 18:48:34 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux Regards, Franta P.S. If you have similar problem and have to switch from "." to "/" separators, don't forget to update your Sieve scripts (with fileinto). And sometimes also reconfiguration of the client is needed (e.g. NGImap4ConnectionStringSeparator in SOGo; and Kontact/KMail stopped working and I had to recreate the account in this client).

[Dovecot] Can't find sieve files
by Chris Kottaridis 23 Apr '14

23 Apr '14

I have been running dovecot on a Fedora 14 host for years and am moving up to Fedora 19. I have things setup to run as a generic user vmail and have all users mailboxes in /var/vmail which is owned by the vmail user. Each user has a Maildir directory and a sieve directory. I also changed sendmail's procmail to run dovecot so it delivers into /var/vmail/<user>/Maildir instead of /var/spool/mail. I just copied the /var/vmail directory from the old machine to the new machine and made all the files there owned by vmail that had the same uid. I then compared the /etc/dovecot/conf.d files and made changes to ty and match the previous configuration as much as possible. I can send mail to a local user and se it show up in the users INBOX. However, when I watch /var/log/maillog when I send the mail I see errors like this: --------------------- script /var/vmail//ckottari/sieve/Active.sieve;name=main script (view user logfile /var/vmail//ckottari/sieve/Active.sieve.log for more information) Apr 22 17:05:46 ckottari-dhcp1 dovecot: lda(ckottari): msgid=<201404222205.s3MM5jJs003128(a)ckottari-dhcp1.wrs.com>: saved mail to INBOX --------------------- When I look at Active.sieve.log: --------------------------------------------------- sieve: info: started log at Apr 22 17:05:46. main script: line 8: error: included personal script 'My RRs.sieve' does not exist. main script: line 9: error: included personal script 'RCPL.sieve' does not exist. main script: line 10: error: included personal script 'New_Incomplete Messages.sieve' does not exist. --------------------------------------------------- Basically, I get an error message for all my scripts that get included by the Active.sieve. The Active.sieve file and all the scripts exist in the /var/vmail/<user>/sieve directory and sieve_dir is set to ~/sieve. So, I am not sure why it can't find them if it can find Active.sieve. Below is my configuration output. This has been working for years in my Fedora 14 host without errors. But, there are some configuration differences that I just kind of guessed at. Any ideas on how to get sieve working would be appreciated. $ dovecot -n # 2.2.12: /etc/dovecot/dovecot.conf # OS: Linux 3.13.5-101.fc19.x86_64 x86_64 Fedora release 19 (Schrödinger’s Cat) login_trusted_networks = 172.25.33.32/5 mail_location = maildir:~/Maildir:LAYOUT=fs 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 mbox_write_locks = fcntl namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { args = dovecot driver = pam } plugin { sieve = ~/sieve/Active.sieve sieve_dir = ~/sieve } protocols = imap sieve ssl = required ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem userdb { args = uid=vmail gid=vmail home=/var/vmail/%n driver = passwd } protocol lda { mail_plugins = " sieve" } Thanks Chris Kottaridis

[Dovecot] one way replication

Hi, anyone using one way (or master/slave) replication instead of master/master ? There is no info in documentation but in sources (src/doveadm/dsync/doveadm-dsync.c) i found some flags which looks like for setting up master/slave switch (c) { case '1': ctx->oneway = TRUE; ctx->backup = TRUE; break; case 'R': ctx->reverse_backup = TRUE; break; So on master i add -1 : replication_dsync_parameters = -1 -d -n INBOX -l 30 -U and on slave -1 -R: replication_dsync_parameters = -1 -R -d -n INBOX -l 30 -U It looks it works, if i but question is if it is production ready. -- [ Ohodnotte kvalitu mailu: http://nicereply.com/websupport/Stano/ ] Pavel Stano | Troubleshooter http://WebSupport.sk *** BERTE A VYCHUTNAVAJTE ***

[Dovecot] dovecot-openssl.cnf - switch to 2048 bits?
by A M 22 Apr '14

22 Apr '14

Hello, Just had a query, from security point of view. Shouldn't dovecot-openssl.conf defaults now be 2048 bits? i.e. default_bits = 1024 I have read that 1024 bit certificates are now deprecated, since Dec 31, 2013. So may be we should have default as 2048 and can be changed manually if someone specifically wants 1024 or lower. Regards, A M

[Dovecot] "Reapplying" sieve rules
by Axel Luttgens 22 Apr '14

22 Apr '14

I did a mistake (shame on me). While migrating accounts on a new server, I didn't pay attention to a detail: sieve_max_actions, that I set to a low value for my testings, but then forgot to raise before the migration. As a result, several redirect-only accounts have now their inbox filled with messages that should have been redirected to "real people", then discarded. Would there be a nice way to "reapply" the sieve scripts, so that the messages of those mailboxes are redirected to their final recipients, the way they should have been upon arrival? Many thanks in advance, Axel

[Dovecot] Trying to get DSpam+Dovecot working with Postfix and local/virtual domains
by Jeremy Doran 21 Apr '14

21 Apr '14

Hi, I'm hoping that someone might be able to help, as I've been going in circles with trying to get the right configuration done here. I'm also not sure whether this is more of a Dovecot or DSpam question, so I'm posting the same to both mailing lists. My goal is to have a mail setup that is as follows: [Incoming email] --> [Postfix] --> [Amavis] --> [DSpam] --> [Dovecot LDA] -+---(local domain)---> /var/mail/${user} | +---(virtual)---> /home/vmail/${domain}/${user}@{domain} As of right now, I have Postfix successfully feeding into Amavis, re-injecting into Postfix with a final delivery for the local domain via procmail, and final delivery for virtual domains via the virtual transport into maildir (but /home/vmail/${user}@${domain}) Virtual domains are being managed by PostfixAdmin. Dovecot is running as the IMAP server. Everything (Postfix, PostfixAdmin, Dovecot) is using a Postgres database as backend for the dynamic maps/authentication. The problem I've been stumbling over is trying to get DSpam to work nicely with both a local domain and virtual domains/mailboxes, and the same for Dovecot, as I would rather like to make use of the Sieve functionality going forward instead of Procmail. I did have DSpam working, but was unable to get the Dovecot antispam plugin working to re-train based on moving mails into/out of a defined 'SPAM' folder, due to permissions relating to how the antispam plugin was calling DSpam. I'm really not wanting to make the local domain into a virtual mailbox domain, because there are users on the system (for that local domain) that already use the password in /etc/passwd for accessing the server for other uses. While there are also people who do that who have virtual mailbox domains, it's a far lower number. Here's what I have so far. Postfix 2.11.0 main.cf (via 'postconf -nf'): alias_database = hash:/etc/aliases alias_maps = hash:/etc/aliases, hash:/usr/local/mailman/data/aliases command_directory = /usr/local/sbin config_directory = /usr/local/etc/postfix content_filter = amavisfeed:[127.0.0.1]:10024 daemon_directory = /usr/local/libexec/postfix data_directory = /var/db/postfix debug_peer_level = 2 debugger_command = PATH=/bin:/usr/bin:/usr/local/bin:/usr/X11R6/bin ddd $daemon_directory/$process_name $process_id & sleep 5 html_directory = /usr/local/share/doc/postfix inet_interfaces = all inet_protocols = ipv4 ipv6 local_recipient_maps = $transport_maps unix:passwd.byname $alias_maps mail_owner = postfix mailbox_command = /usr/local/bin/procmail -a "$EXTENSION" mailq_path = /usr/local/bin/mailq manpage_directory = /usr/local/man mydestination = $myhostname, localhost.$mydomain, $mydomain mydomain = critter.net myhostname = cornix.critter.net mynetworks = 127.0.0.0/8, 46.4.24.15/32, [::1]/128, [2a01:4f8:131:4263::]/64, 184.73.168.110/32, [2001:470:7:12ba::]/64 mynetworks_style = host myorigin = $mydomain newaliases_path = /usr/local/bin/newaliases queue_directory = /var/spool/postfix readme_directory = /usr/local/share/doc/postfix receive_override_options = no_address_mappings recipient_delimiter = -

Good evening all, Does anyone know of a doveadm command I can use to remove (delete) all attachments from an mdbox Inbox? I prefer to save my attachments and have a sleek Inbox... but sometimes I forget. A command I can feed into a cron job would be ideal. Many thanks, -Mark

[Dovecot] Changing SSL certificates - switching from self-signed to RapidSSL
by Charles Marcus 19 Apr '14

19 Apr '14

Hi all, Ok, been wanting to do this for a while, and I after the Heartbleed fiasco, the boss finally agreed to let me buy some real certs... Until now, we've been using self-signed certs with the following dovecot config: ssl = required ssl_cert = </etc/ssl/ourCerts/imap.pem ssl_key = </etc/ssl/ourCerts/imap_key.pem Now, I've created new keys/certs and the CSR, got the new certs from RapidSSL (and also downloaded their Intermediate bundle), saved everything per their instructions, which say to reference them as follows: ssl = required ssl_cert_file = /etc/ssl/ourNewCerts/mail.ourdomain.com.crt ssl_key_file = /etc/ssl/ourNewCerts/mail.ourdomain.com.key ssl_ca_file = /etc/ssl/ourNewCerts/RapidSSL_Intermediate.crt But my current config doesn't have the _file for the variable names, and the wiki doesn't use them, so I'm planning on setting these to: ssl = required ssl_cert = /etc/ssl/ourNewCerts/mail.ourdomain.com.crt ssl_key = /etc/ssl/ourNewCerts/mail.ourdomain.com.key ssl_ca = /etc/ssl/ourNewCerts/RapidSSL_Intermediate.crt Anyone else ever used RapidSSL certs? Does this look correct? Thanks, Charles

Short answer: maybe. I got these errors when I switched from a self-signed to CA signed cert, and the client had an open mail session: Feb 22 02:10:32 imap-login: Disconnected (no auth attempts in 0 secs): user=<>, rip=x.x.x.x, lip=y.y.y.y, TLS: SSL_read() failed: error:14094418:SSL routines:SSL3_READ_BYTES:tlsv1 alert unknown ca: SSL alert number 48, session=<w4Lm8vvypgCJUgmg> Not quite the same as your's, but if you call the client up and ask them to restart their mail client, I'm fairly confident these will go away, as for my user. You might get some weirdness if for some reason the client does not have the intermediate CAs cached. I ran into this problem with our certs -- some RH distributions did have the intermediate CA certs in its store. Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] Hash Verification with doveadm
by Andreas Krischer - AKbyte 19 Apr '14

19 Apr '14

Hello! I have a problem with the doveadm tool. I’m trying to verify a hash from my MySQL-Db with the following command: doveadm pw -p '123' -t '{SHA512-CRYPT}$6$e3TLkiahfHFv29/J$8etBEtmbh06B72kc1TpetT/k8aHkQrJAPQVpTGDYuzyHZX4MwU2PeL2cIupNEoUUGt6SLB0N7xNqbbqp/5OZo.' I'm expecting that it says verified or not, but it prompts for a password, so the „-p“ parameter does not work. I need this, because I want to use the verification in a shell script and for that it have to work without a prompt. I hope you guess what my problem is :) My configuration: # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 3.2.41-042stab078.27 i686 Debian 7.4 reiserfs auth_mechanisms = plain login mail_location = maildir:/var/vmail/%d/%n/Maildir 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 { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } protocols = " imap sieve pop3" service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } } ssl_cert = </etc/ssl/certs/mailserver.pem ssl_key = </etc/ssl/private/mailserver.pem userdb { args = uid=vmail gid=vmail home=/var/vmail/%d/%n driver = static } protocol lda { mail_plugins = " sieve“ } Regards, Andi PS: Sorry for my bad English, I’m just a 16 year old guy from Germany ...

[Dovecot] Dovecot Replication setup
by Nikolaos Milas 17 Apr '14

17 Apr '14

Hi, I am trying to setup a master/master replication with dsync (according to the first part of: http://wiki2.dovecot.org/Replication) Sorry if this question sounds foolish, but I would like to ask/confirm whether the indicated setup is required on *both* servers participating in the master/master replication. It seems to me that both need it, but I would like to confirm, just in case. Both servers are running 2.2.12 on CentOS x86_64 (5.10 and 6.5 respectively) and users are virtual over ldap. I might have more questions in the near future, but this is a starting point. Please clarify. Best regards, Nick

[Dovecot] How to disable Director service?
by Wesley Huang 17 Apr '14

17 Apr '14

Hi All, Does anyone know how to disable the Director service. In our current running Dovecot 2.2.4, if the director configuration is commented out and Dovecot has no errors nor warnings. But the version 2.2.12 I'm testing with gives out fatal errors. We have dedicated Dovecot Director servers that serve the public frontend and separate dedicated imap/pop3 servers on the backend internal network. With the new version, Dovecot is always trying to start Director service and I couldn't find a way to stop Dovecot from giving out errors. 1. When the entire Director configuration block is commented out, there errors: dovecot: director: Fatal: No inet_listeners defined for director service (for standalone keep director_servers empty) dovecot: master: Error: service(director): command startup failed, throttling for 2 secs 2. When the director_servers line is configured as "*director_servers = *", there errors: dovecot: director: Error: Empty server list dovecot: director: Fatal: Invalid value for director_mail_servers setting master: Error: service(director): command startup failed, throttling for 2 secs 3. If the director_servers and direcotr_mail_servers are configured the same as our Director servers, there errors: dovecot: director: Fatal: director_servers doesn't list ourself dovecot: master: Error: service(director): command startup failed, throttling for 2 secs Does any one know how to disable this director service? We don't need the director service on the backend. Cheers, Wesley

[Dovecot] Move of mail folders to other mail account on same server
by Jan Valvekens 16 Apr '14

16 Apr '14

Hi, I'd like to move mail folders from one mail account to another mail account on the same server. Moving the folders via my mail client (Thunderbird) takes a long time. Therefore I wondered whether it's not possible to simply move the files on the server itself. If I unsubscribe to the folders in my source account, then move the folder and subscribe to the folders in my target account: will that work? I run dovecot version 2.1.15 Thanks a lot, Jan

[Dovecot] Segmentation fault running doveadm index (lucene) on a big mailbox

[Dovecot] migration advice
by Raphael Bauduin 15 Apr '14

15 Apr '14

Hi, I am preparing a migration from courier-imap to dovecot. The maildir is in each user's home directory, and /home is mounted by NFS. All this running in a kvm virtual machine. My plan would be to create a new virtual machine (with another IP) with dovecot, mounting the same /home, and switching a couple of users to dovecot for testing purpose. If the tests go well, I would then migrate the other users and assign the IP address of the courier imap kvm to the dovecote kvm. Does that make sense? Or can it be problematic to have some users switched to dovecot while their maildir directory is still accessible to courier-imap? Looking forward to reading your feedback, thanks in advance! Raph

Re: [Dovecot] integration of old mails into new dovecot Maildir
by K. C. Mohan - Personal 15 Apr '14

Thank you for your prompt reply and timely help. I will try to be very explanative in describing my situation. I will begin first with answering the questions you asked; 1) how are the messages storred on the old server, which storage backend do you use, maybe Maildir? Yes, Maildir. Dovecot version is 2.1.7. Virtual users are authenticated by mysql backend. Login is plain login. 2) the storage backend on the new server? Maildir. Dovecot Version 2.2.9. Mysql virtual users authentication. Plain login 3) do you care about the message UIDs? I Would like to preserve the UIDs as much as possible. However, the most important thing is for the users to have access to their old emails. 4) How many users do you have (approx.) and can you access the user's mailboxes via IMAP, e.g. using a master user or do you know their password or can you switch to a known password during migration of one particular user? I have about 50 total users. I can access their mailboxes via imap but I don't have their password handy. Mysql database with the userdata and passwords was imported into the new new server so, the users can get authenticated into the new server with the old server password. 5) Did you've changed namespaces? No. I did not change namespaces. - From your first post I figure that the basic mail server functionality of the new server is working, most importantly login, message delivery and retrieval. Yes, the new server is functional and all the users are able to log in, view delivered messages and retrieve the messages into their mail clients. However, they cannot view any old messages or retrieve any old messages. Here is the dovecot.conf of the old mail server; protocols = imap pop3 log_timestamp = "%Y-%m-%d %H:%M:%S " mail_location = maildir:/var/vmail/%d/%n mail_privileged_group = mail first_valid_uid = 6060 ssl_cert= </etc/ssl/certs/dovecot.pem ssl_key =< /etc/ssl/private/dovecot.pem #ssl_ca = </etc/ssl/certs/gd_bundle.crt ssl = yes #ssl_cert = </etc/postfix/ssl/smtpd.crt #ssl_key = </etc/postfix/ssl/smtpd.key protocol imap { mail_plugins = autocreate quota imap_quota } protocol pop3 { pop3_uidl_format = %08Xu%08Xv mail_plugins = quota } protocol lda { mail_plugins = quota sieve quota_full_tempfail = yes rejection_reason = Your message to <%t> was automatically rejected:%n%r%n%nThe Subject of your message was: %s auth_socket_path = /var/run/dovecot/auth-master log_path = /var/log/dovecot-deliver.log postmaster_address = postmaster(a)sbm1.motherindia.com # sieve_path = /var/sieve/global.sieve } auth_mechanisms = plain login cram-md5 auth_debug = no auth_debug_passwords = yes auth_verbose = no auth_verbose_passwords = no disable_plaintext_auth = no instance_name = dovecot login_greeting = Dovecot ready. mail_debug = no passdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } userdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } -----Original Message----- From: Steffen Kaiser [mailto:skdovecot@smail.inf.fh-brs.de] Sent: Monday, April 14, 2014 2:18 AM To: K.

[Dovecot] About the "nologin" extra field
by Axel Luttgens 14 Apr '14

14 Apr '14

Hello, While experimenting with the "nologin" extra field, I met a possibly overlooked behavior. Let's suppose the user database has those two columns: enabled: the user may/may not login (account active/not active) nologin: NULL if the mailbox is available, '!' if it is currently suspended (for maintenance reasons) The password_query: password_query = SELECT password, nologin, 'Maintenance' || nologin AS reason, [...] FROM [...] WHERE [...] AND enabled [...] Let's then experiment with pop connections. With: enabled set to false, nologin set to '!' the right password provided, following reply is emitted after an authentication failure delay: -ERR [AUTH] Authentication failed. So, as expected, the nologin value behaves as a "don't care" one. With: enabled set to true, nologin set to '!', the right password provided, following output is immediately emitted: -ERR [AUTH] Maintenance! Again, this is the kind of behavior I was expecting. With: enabled set to true, nologin set to '!', an incorrect password provided, there's the failure delay but the output still is: -ERR [AUTH] Maintenance! Here, I'm a bit dubitative... ;-) The delay seems to make the code's intent clear: to act as in the case of an authentication failure. But, notwithstanding the somewhat misleading explanation provided to a legitimate user with such a reply, isn't one unduly disclosing information about an account existence? Is this supposed to behave that way? If yes, what's the rationale? TIA, Axel

[Dovecot] Feature Request: handle mail connections of the same user from a same IP using just one mail process
by morrison 14 Apr '14

14 Apr '14

Hi, Dovecot Wiki states that mail process (IMAP/POP3) is able to handle multiple client connections as the same time to save CPU and memory resources (client_limit > 1). Although this approach is not recommended due to latency and probably security issues, it does help increase the overall capacity of a mail server. Is it possible (or planned) to add a feature such that mail client connections of the same user from a same IP are directed to a same mail process? In most cases, such connections come from a same mail client (e.g. in Thunderbird, each mailbox is a connection). The end user (human being) can work on one mailbox at a time, the latency will be non-obvious. And since all data being processed belong to the same user, security is a non-issue. Thanks,

Hello, I just have a minor question. (Using Fedora 16) My current dovecot (2.2.10) was compiled with db4 (4.8.30). I am thinking of recompiling same dovecot (2.2.10) with libdb (5.2.36). I will be trying on live server so just wanted to know if this will this break any indexing or anything else? (Recompiling for Heartbleed, so might as well switch db version) AM.

Re: [Dovecot] replication + attachment sis + zlib bug ? (HEAD version from xi.rename-it.nl)
by Pavel Stano 11 Apr '14

Yes, exactly. I look at the code and find out there is functionality for that. Dovecot store attachments in base64 format without decoding if there are longer lines with more base64 blocks (4chars). So these attachments get deduplicated but are not decoded. But it don't work if last line is buggy. I think i fixed it. It looks like it works, but i test only one mailbox.

[Dovecot] FTS autoindex problem
by lee_yiu_chung＠yahoo.com 11 Apr '14

11 Apr '14

I tried to implement a solr search server, but I found some unexpected behaviour when I turn on autoindex according to http://wiki2.dovecot.org/Plugins/FTS. I found that all autoindexed email are using "user1(a)example.com" as username, as shown in maillog: indexer-worker(user1(a)example.com): Indexed 1 messages in INBOX However, all manually indexed email (triggered by IMAP server search) are using "user1" as username, as shown in maillog: indexer-worker(user1): Indexed 2927 messages in INBOX. I am using "user1" as login name, so all autoindexed mails don't appear in search result. How can I use "user" as the username in autoindex? BTW, I do have a few mailboxes in the format user2(a)virtualmail.example.com, which requires full email address as the login name. How can I autoindex emails that automatically distinguishes user1(a)example.com (using "user1" as username) and user2(a)virtualmail.example.com (using "user2(a)virtualmail.example.com" as username) given that the previous question is solved?

[Dovecot] dsync deleted my mailbox - what did I do wrong?
by Benjamin Podszun 10 Apr '14

10 Apr '14

Hi. Mostly annoying: I migrated from one machine to another, made sure the target host worked as expected, updated mx records and - after a couple of days - signed it off as good. This is just my private machine, no big deal if something goes wrong.. Everything's fine? Good, let's migrate my inbox from the old machine. There's no direct connectivity between those servers, so what I did was: (old server) sudo -u vmail dsync -u dar(a)darklajid.de backup maildir:/tmp/mail_backup/ Works fine, got my maildir. Tar'd it up, moved it to the new server. Now how do I import those mails? Ah, let's use the same command, with -R? (new server) sudo -u vmail dsync -u dar(a)darklajid.de -R backup maildir:/tmp/mail_backup Error: Mailbox INBOX sync: mailbox_delete failed: INBOX can't be deleted. Wait. What? Sure enough, the last couple of days are gone, the target mailbox is completely empty. I read the man page over and over again, but failed to see the problem. I even thought for a moment that _maybe_ dsync backup is one-way only (even if that failed as well) and tried the same command with mirror. Exactly the same output, same result, empty target mailbox. In the end I succeeded to import the mails with doveadm import, completely lost a number of days of mails. My fault, sloppy not to back the up again, but I still don't think that this should happen. Ever. My question now is: - where did I fail (ignoring the backups, please. That's .. something I know) - Can I use dsync ... for backups? I don't think that this is a good idea after yesterday night? - Should dsync EVER try to delete mailboxes? Even 'special' mailboxes? Should it warn about that, asking for a --force switch or something? Any insights would be appreciated. At this point the damage is done, but I'd like to learn how to do better. Ben

I just installed dovecot 2.2.9 on to a new server and want to transfer all the old mails into the email accounts I imported from the previous server into MySQL database. I am not able to view the subfolders and or old mails that I copied into their respective maildir folders. I was very much appreciate if anyone could let me know how to import old mails into the new server. All I see, is the new mails that have come into the account since I started dovecot service in the new server. --- This email is free from viruses and malware because avast!

[Dovecot] Heartbleed openssl vulnerability?
by John Rowe 10 Apr '14

10 Apr '14

Do we know if dovecot is vulnerable to the heartbleed SSL problem? I'm running dovecot-2.0.9 and openssl-1.01, the latter being intrinsically vulnerable. An on-line tool says that my machine is not affected on port 993 but it would be nice to know for sure if we were vulnerable for a while. (Naturally I've blocked it anyway!). Thanks John

[Dovecot] Director NFS backups
by Murray Trainer 10 Apr '14

10 Apr '14

Hi All, What is the recommended method of taking backups of user mailboxes when using the Director setup with NFS backend mail storage? Is there any way to avoid the likely NFS locking issues by backing up the filesystem directly or do I have to do some sort of dsync method. If I have to use dsync can I dsync the mailboxes to compressed copies of the mailboxes without requiring another dovecot server to do the dsync. Thanks for you responses. Murray

That ought to be the default: http://wiki2.dovecot.org/POP3Server (Section Session locking) Did you set pop3_lock_session=yes somewhere? Locking is good if the client connection is stable: if you disable locking, you could end up with a scrambled mailbox as two or more users access it at the same time.

[Dovecot] Override maildir for just a few users
by Charles Marcus 09 Apr '14

09 Apr '14

Hi all, Currently, I have mail_location = maildir:~/Maildir set and all passdb and userdb lookups are SQL based (doveconf -n pasted below). However, I want to override the users maildir location - and *only* the maildir location - for just a few users. I was thinking the easiest way would be to add a simple flat file based userdb that is checked before the SQL based one, where I can define a different maildir for these users. So, basically, dovecot checks the flat file first, and if the user isn't found, falls back to SQL. I still want all AUTH to go through SQL... It seems like this should be fairly simple, but after reading the wiki for a few days, I'm just not sure... This is on a production box, so I have to be careful (note to self - MUST set up testing box for things like this)... Is anyone else doing anything like this, and if so would you be willing to share sanitized configs? Thx, -- Best regards, Charles

[Dovecot] Sieve (randomly?) flagging messages as \\Seen \\Deleted
by Emanuele Balla (aka Skull) 09 Apr '14

09 Apr '14

Hi, I'm trying to debug (without great results, so far) a very weird behaviour in my environment. Sorry if this came out in another form before, but I've not been able to find out anything resembling what I'm experiencing, so far... OS is a debian wheezy and dovecot is the version provided by the OS: # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-4-amd64 x86_64 Debian 7.4 The system uses postfix with virtual users, credentials and maildir locations stored on mysql, local delivery through LMTP and sieve+managesieve available to users (although managesieve only listens on localhost and is only usable through the webmail interface). FWIW, I've been running 10-20 systems just like this one (mostly with earlier dovecot versions and using LDA when LMTP wasn't available yet) for many years, and this is the very first time I'm so puzzled I end up searching for help here :-| Even though the system has been working for months (more or less 1 year now) without big changes, a strange behaviour appeared (or became evident enough to be noticed) in the last few days, apparently involving sieve and some sort of "default/hidden" action triggered by something. Or at least that's what I ended up supposing. The problem in short: Messages I expected to find in certain folders were simply not there, although sieve logs reported them as delivered in those same folders. By manually inspecting the maildir, I actually found the messages, but they were all flagged as \\Seen + \\Deleted and therefore not displayed by the MUA (ThunderBird in my case). I initially supposed this to be a TB issue, 'cause nothing in my sieve script ever flags messages that way, but I could not find anything on my client explaining that. Then I received a notification from one of my users saying he was experiencing exactly the same, except he's using mutt as IMAP client; that restricted the issue to server-side interactions only, but nothing useful could be found in logfiles... This is the "relevant" portion of a "dovecot -n" output: [...] plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve sieve_extensions = +vacation-seconds +editheader sieve_vacation_default_period = 2d sieve_vacation_dont_check_recipient = yes sieve_vacation_max_period = 30d sieve_vacation_min_period = 2s sieve_vacation_use_original_recipient = no } [...] protocol lmtp { mail_plugins = sieve hostname = alternativename.bofhland.org } There is no sieve_(before|after) script in addition to what users create for themselves. The mailboxes are relatively low-traffic; most of the traffic is caused by a single role address translated into multiple-recipients alias going to many of the users (100-300 messages per day). Almost all the users using sieve rely on it to store traffic for that role-address in a dedicated folder, including the mutt user and myself. Not that's all that important, but means that most of the misbehaviours observed (but not all) are observed in these folders. I enabled mail_debug, but there's nothing unusual in there AFAICT: it just says: - using the following location for user's Sieve script: /blabla/.dovecot.sieve - opening script /blabla/.dovecot.sieve - script binary /blabla/.dovecot.svbin successfully loaded - not saving binary /blabla/.dovecot.svbin, because it is already stored - executing script from /blabla/.dovecot.svbin - stored mail into mailbox 'DedicatedFolder' And it does, except the message happens to be flagged as seen and deleted... In order to try restricting what may be causing the issue, I added... removeflag "\\Deleted"; removeflag "\\Seen"; ...to the rule sending messages to the dedicated folder cited above for my mailbox. The problem apparently disappeared for me as long as I kept those in place. This should mean (I suppose) that the decision of flagging messages that way is taken before the users' sieve scripts are applied (sort of "hidden sieve_before"). The problem is hard to replicate as it's apparently not deterministic: the same message is being flagged for one user but not for the other, different messages between the same people and with the same thread are sometimes flagged and sometimes not. Something is surely triggering whatever is causing this, but it's not evident enough for me to point a finger and say "ha ha!" (https://www.youtube.com/watch?v=rX7wtNOkuHo) So, a question for people knowing pigeonhole's internals: does it ever choose to mark messages as described above for any reason? If yes, I may be triggering this behavior with something I recently added/modified, and at least I'll have something to focus my investigation on. :-| Any other suggestion is obviously welcome...

[Dovecot] sieve pigeonhole vacation filter responding when recipient is not explicitly listed
by Milan Cvetkovic 09 Apr '14

09 Apr '14

Hi dovecot.org, When I set up vacation filter for a mailbox, the vacation response is generated even though none of the addresses in the email are same as the mailbox address itself. I have example email sent to "aliastouser(a)mpathix.com" which gets delivered to "user(a)my.domain.com" by dovecot-lda. The invocation command is: # /usr/lib/dovecot/dovecot-lda \ -d user \ -f john.doe(a)somewhere.com \ -a aliastouser(a)mpathix.com \ -p /tmp/test.email # cat /tmp/test.email Message-ID: <test3> From: John Doe <john(a)somewhere.com> To: aliastouser(a)mpathix.com Subject: test3 vacation response as aliastouser This is the only line in test.email. Here is the vacation filter: if true { vacation :days 1 :addresses ["user(a)my.domain.com"] text: Please ignore this message, I am only testing vacation filter . ; } /var/log/mail.log shows that sieve vacation sends vacation, (and after succeeding attempts, discards due to already sent address) Apr 9 13:37:21 mx01 dovecot: lda(user): sieve: <test3>: sent vacation response to <john(a)somewhere.com> Apr 9 13:37:21 mx01 dovecot: lda(user): sieve: msgid=<test3>: stored mail into mailbox 'INBOX' ... Apr 9 13:40:15 mx01 dovecot: lda(user): sieve: msgid=<test3>: discarded duplicate vacation response to <john(a)somewhere.com> Apr 9 13:40:15 mx01 dovecot: lda(user): sieve: msgid=<test3>: stored mail into mailbox 'INBOX' Attached is the doveconf -n output. Any help is appreciated. Milan.

Hi, Is there any way to disable sieve forwards to all domains except one. Users should be able to forward their mails to only one specific domain. If not then any idea on how this feature can be implemented ??. -- View this message in context: http://dovecot.2317879.n4.nabble.com/Prevent-sieve-redirects-to-external-do… Sent from the Dovecot mailing list archive at Nabble.com.

Re: [Dovecot] Heartbleed openssl vulnerability?
by Jake Alley 09 Apr '14

09 Apr '14

It's an interesting issue. In my experience "stale" passwords are rarely used to compromise systems. However, passwords tend to end up on sticky notes and even worse, in email databases regardless. As far as compromised email passwords, they seem to mostly come from infected clients and insecure public logins as far as I can tell. A server can control the later, but not the former. I know of a major accounting software that forces Admin users to change their passwords every few months under certain circumstances. Those passwords always end up in emails to fellow users, so in that case forcing people to change seems to be definitely counterproductive. IMV the moral of the story is that you can't crypt your way into a 100% secure world. You need other forms of checks & reconciliations that are disjoint from purely cryptographic infrastructure. For instance ask Mt. Gox and Bitcoin if they agree in hindsight, and Heartbleed is a very good example of this concept. Thanks, Jake On 4/9/2014 10:27 AM, Reindl Harald wrote: "change passwords from time to time is always clever" is a strawmans argument with no context to the issue, forcing people to change their passwords all the time for no good reasons leads mostly to completly insecured passwords to remember them easier or have them on a sticky on the screen or under the keyboard the word "counterproductive" describes that policies perfectly

[Dovecot] Migration to Dovecot 2.2.12 - How to trigger full site indexing
by kadafax＠gmail.com 09 Apr '14

Hi list, We are in the process of migrating our old (dovecot 1.2.4 based) mail system to the new one: - Centos 6 x86_64 - Dovecot 2.2.12 - Users in an openldap directory - clucene FTS I'm trying to trigger a full indexing for all the user and all their mailboxes (avoiding them to individually trigger it using a search within their MUA). I'm trying to use the "doveadm index" command. First question, is there some sort of 'wildcard' option for the name of the mailbox to index, as I dont know all the mailboxes's names the users have created (beside the regular Sent Inbox Trash and Drafts ? Second question I've tried: # doveadm -D index -A Sent which gave me: doveadm(root): Error: User listing returned failure doveadm: Error: Failed to iterate through some users Can the '-A' option work with ldap backend ?

[Dovecot] Dovecot LDAP issue

Unfortunately, when I try to send e-mail from a user who's not in the testou container I get the following error: Sender address rejected: User unknown in virtual mailbox table> #SMTP#. I'm assuming this happens because dovecot is not able to to lookup up that user since that user is outside the testou container. A lot of the AD users are in different places inside the AD structure and I need to be able to configure dovecot to look from the root of the AD structure down. I changed the base to this: base = dc=domain,dc=tld but it simply fails to lookup any users at that point. How would I go about getting dovecot to start at the top of the domain and look at every nested OU within AD? thanks a lot D

[Dovecot] Debugging doveadm expunge
by Andy Hawkins 08 Apr '14

08 Apr '14

Hi, I'm a recent convert to dovecot, and in general it is all working fine. However, I have a number of cron jobs set up to purge old messages from mailboxes. These don't seem to be doing what I would expect. Is there any way of debugging this process? Some way of seeing what messages it's checking, and why each one matches or fails to match? For example, I'm running this: doveadm expunge -u andy mailbox "News Reports" savedbefore 90d from the crontab of user 'andy'. I'd expect the specified folder to only contain 90 messages (I get one 'News Report' per day) but in actual fact there are 1428 in there! Any advice would be appreciated. Thanks Andy

[Dovecot] dsync replication questions
by Nikolaos Milas 07 Apr '14

07 Apr '14

I am running two servers with Dovecot v2.2.12 on CentOS x86_64 (5.10 and 6.5 respectively) and users are virtual over ldap. I have setup our main internal server (vmail.example.com) with dsync replication according to the first part of http://wiki2.dovecot.org/Replication. The second one (vmail1.example.com) will be the failover server which we want to be a real-time mirror (but can be manipulated directly and it should propagate changes back to vmail.example.com) When I started the server (vmail.example.com) mirroring started and completed fine (after a few hours). However, since then, I am not seeing a continued mirroring between the two. I would expect changes to one of the masters to be propagated in real time to the other - which does not happen. If I manually run (on vmail.example.com) dsync -u imaptester mirror ssh -l root vmail1.example.com dsync -u imaptester then these two accounts are synced. Question 1: Shouldn't mirroring continue automatically in real time (having configured it as in the first part of http://wiki2.dovecot.org/Replication)? If not, what should I do to enable such a real-time (or near-real-time) sync? Note that I have not configured "replication_dsync_parameters" as noted at the above page. Question 2: Where can I find documentation about "replication_dsync_parameters" and about "the doveadm sync command" (referred to at the same page)? I have not been able to locate such a documentation/wiki page. Question 2a: What do options "-d -N -l 30 -U" signify in "replication_dsync_parameters = -d -N -l 30 -U"? Thanks, Nick

[Dovecot] Dovecot IMAP Authentication issue with Vpopmail

Hello All, i've configured a qmail server (for office) under Ubuntu 12.04 server following this guide- http://www.connor.net.au/tutorials/qmail/qmaillite/ everything working just fine except dovecot IMAP. i've followed this section for dovecot- http://www.connor.net.au/tutorials/q...te/dovecot.php<http://www.connor.net.au/tutorials/qmail/qmaillite/dovecot.php> but when i go to telnet 143 and try to login with username/password, it failed and showing error: ** BYE Internal error occurred. Refer to server log for more information.Connection closed by foreign host.* i think there may be some authentication issue with vpopmail and dovecot. POP and SMTP both working. but why not IMAP? i can't also use webmail (i.e. squirrelmail) as it don't working with IMAP. it's showing- *connection dropped by IMAP server *error while trying to login. i'm looking forward to a solution here. any qmail+vpopmail expert here? plz help. Thanks in advance. B/R

[Dovecot] mdbox with mail_attachment_dir per user in 2.2.12
by Pavel Stano 04 Apr '14

04 Apr '14

Hello, we have 2 netapp arrays with 2 volumes and we need to store our mail data in one or other volume for every user. We want keep data for one user in one volume only. So we would like to have 2 separate mail_attachment_dir, one on every volume. But in latest version 2.2.12 it look like it is only possible to set one global mail_attachment_dir. I have an idea with 2 separate dovecot instances per machine with different mail_attachment_dir. Or it is possible to somehow specify it per user ?

[Dovecot] imap / IPv6 problems?
by Egbert 04 Apr '14

04 Apr '14

Hi, I have this intermittant problem. When sending an email it *sometimes* takes ages before the process finishes. The process seems to hang in moving the message to the sent items" folder". When I disable the IPv6 stack in the network config (this is MS Windows 7), the hanging process immedialetely completes! This makens me think that is has to do with the IP stacks. Another observed effect is a long "rotating wheel" when just klicking on an imap folder before the listing in the right pane updates. Here the same trick solves the problem. I use Thunderbird on W7 as client and have my mail (3 accounts) on a remote mailserver. I have full control over that server which can become handy... Th emailserver is Ubuntu 12.04 LTS with postfix and Dovecot (2.0.19) from the standard repo's. My IPv6 connections is a native IPv6 from my ISP (xs4all.nl). I have no reason to think that the IPv 6 connecition itself is the problem. Any advise to investigate this problem is welcome. Egbert Jan, NL
