Authcache and user changing
by Lazy 13 Apr '15

13 Apr '15

Hi, I have noticed that during auth cache hits usernames are not updated. (We use ldap backend and change username with user_attrs = uid=user, mailMessageStore=home, mailQuotaSize=quota_rule=*:bytes=%$ cold cache lmtp(14414): Debug: auth input: testmon_testmon home=/vmail/te/testmon_testmon quota_rule=*:bytes=104857600 lmtp(14414): Debug: changed username to testmon_testmon lmtp(14414): Debug: Added userdb setting: plugin/quota_rule=*:bytes=104857600 hot cache lmtp(14715): Debug: auth input: iqmon(a)mon.test.pl home=/vmail/iq/testmon_testmon quota_rule=*:bytes=104857600 lmtp(14715): Debug: Added userdb setting: plugin/quota_rule=*:bytes=104857600 this kills our dictionary based quota (users have multiple quota instances depending on timing and alias the email was delivered to. Is there a way to force addition of user to the auth cache ? -- Michal Grzedzicki

special_use folders
by Roman Gelfand 13 Apr '15

13 Apr '15

My setup is postfix mail gateway/spamassassin on one machine and dovecot mail box server on another machine. Will the following configuration work? 1. On the mail gateway, I install dovecot-lmtp and use it to deliver locally spam. 2. On the mailbox server, I configure special use junk folder to point mail gateway's spam folder via nfs. If this is correct, how can I configure special use folder to point to a path (variable based on email) which is different from default path? If there is a different way to handle this, I would interested. Thanks in advance

dovecot debug message help required
by Rajesh M 13 Apr '15

13 Apr '15

hi i was carrying out some testing using qmailtoaster with dovecot on a centos 64 server i am connecting to the mailbox using a windows machine with outlook across the lan. the mailbox is around 7gb in size with around 12000 emails spread across multiple folders and i am trying to sync the mailbox folders to by creating an account imap account in outlook. the mails are getting downloaded in the imap folder but the sync does not complete and outlook throws an error. Task 'Synchronizing subscribed folders for user(a)mydomain.com.' reported error (0x800CCC0F) : 'Outlook cannot synchronize subscribed folders for user(a)mydomain.com..

Disabling of userdb/passdb modules using config statements
by Jeroen Massar 13 Apr '15

13 Apr '15

Hola, Debian (and possibly other distros) use the /etc/dovecot/conf.d/* setup where default config files are stuffed and then one can just add a 99-myconfig.conf et voila, variables are overruled. This allows the distro to supply updates to the files at package upgrade time without any/much user intervention. The problem (for me ;) is that the system comes provided with: auth-system.conf.ext containing: passdb { driver = pam } userdb { driver = passwd } Hence pam & /etc/passwd based are always enabled. This while I don't have any local users. Replication seems to then always pick up the local users, which are vmail + nobody (65536). doveadm user '*' thus reports vmail, nobody + virtual users Setting: first_valid_uid = 5000 last_valid_uid = 5000 only keeps vmail in there, but apparently some module (guess replication) is still able to figure out that 'nobody' exists: Apr 10 09:48:25 mail dovecot: doveadm(IPADDR,nobody): Error: Mail access for users with UID 65534 not permitted (see first_valid_uid in config file, uid from userdb lookup). Apr 10 09:48:25 mail dovecot: doveadm(IPADDR,nobody): Error: dsync-server: User init failed Apr 10 09:49:38 mail dovecot: doveadm(nobody): Error: sync: Failed to start remote dsync-server command: Remote exit_code=75 and on the other side: Apr 10 09:54:38 mail dovecot: doveadm(nobody): Error: sync: Unknown user in remote This can be resolved by commenting out the entries in auth-system.conf.ext but then I'll have to do that again at package upgrade time. Hence, would it be a cool option to be able (in the 99-myconfig.conf) file to put: passdb { driver = pam enabled = false } userdb { driver = passwd enabled = false } And thereby disabling those modules completely? Thus avoiding upgrade conflicts etc. Greets, Jeroen

Calendar and address book with Dovecot
by mimicafe＠gmail.com 10 Apr '15

10 Apr '15

Hi all I recently install Postfix and Dovecot, and so far so good. My assumption was that calendar and address book (similar to Gmail calendar or address book) are part of Dovecot. However I do not see anything concerning them in any of the docs I have read so far. What other software (ideally open source, free) do I need in other to have Calendar and address book so my users can manage their contact on their phones or computer? I have looked at Roundcube already, but my requirement is not necessarily to provide web mail. Thanks Mimi

pop3 retr responses too large lines - Fails with current python's poplib
by Guillermo M. Narvaja 10 Apr '15

10 Apr '15

Since December 2014, clients using the Python poplib library (getmail in my case) started to limit the line length of RETR and other command responses sent from the server to 2048 bytes: See https://bugs.python.org/issue16041 (Included at least in Python-2.7.9) Dovecot doesn't have line split in the POP3 module, so Python fails to retrieve messages with long lines. RFC 1939 says: " Responses in the POP3 consist of a status indicator and a keyword possibly followed by additional information. All responses are terminated by a CRLF pair. Responses may be up to 512 characters long, including the terminating CRLF. " I think dovecot-pop3 should split it's output in lines of at least 512 characters. Or at least it should have a "pop3_max_line_length" setting (like "imap_max_line_length").

I would not be surprised if this was related to a broken index, as the other side effect I saw during this sync was an ever-expanding maildir (read: sdbox), multiplying itself during sync, keeping large amounts of the the .temp.<xxxx> in the dir, never moving them to a final directory. That was resolved by stopping dovecot, then deleting the broken sdbox (backups++) and performing a 'dovecot force-resync -u user Folder' on the source. Maybe there was a race somewhere while syncing the large amount of data over; seems that everything is okay now though. Greets, Jeroen

sa-learn with remote Dovecot folders
by Andreas Kasenides 10 Apr '15

10 Apr '15

Hi all! The set-up I have is a classic one: 1. one or more Dovecot relay/directors Postfix SMTP servers in DMZ 2. one or more backend IMAP/SMTP servers on the inside network 3. There may or may not be separate incoming or outgoing designated SMTP servers. Now the desired functionality is (of course): 1. relay machines receive messages from outside AND inside 2. relays check for all the bad things (spam, viruses etc). 3. for incoming messages relays check for valid local users and reject messages for invalid users 4. after all checks are done incoming messages are transferred to the backend systems where they are accessed via the Dovecot directors While all the above works nicely, the problem I have is how to train my spamassassin (used by amavisd) on the front ends when all messages are on the back ends. Of course transferring the spam detection procedures internally is not such a great option.Am I missing something? I tried googling for info but nothing substantial turned up. Thanks. -- Andreas Kasenides Senior IT Officer Dept. of Computer Science, University of Cyprus Tel: 22892714, Fax: 22892701 (5B4ANK)

gmail-migration: archived mails in \ALL
by Peer Heinlein 10 Apr '15

10 Apr '15

Hi, I don't completly understand http://wiki2.dovecot.org/Migration/Gmail I can't find the documentation for the -a and the -F Flag. I'd like to migrate ONLY archived mails from an existing gmail-Account. So I'd have to import all Mails from the \ALL-Folder that does NOT have any virtual folder flags set. I tried to use this command: doveadm -D -o imapc_user=user(a)example.com -o pop3c_user=user(a)exampe.com -o imapc_password=secret -o pop3c_password=secret -o imapc_host=imap.googlemail.com -v backup -m '[Gmail]/Tutti i messaggi' -F '-$GmailHaveLabels' -x \Flagged -x \Junk -x \Trash -x \Important -R -u user(a)example.com imapc: But it looks like it's importing too many mails and not only the archived mails without Flags. How do I have do understand -F '-$GmailHaveLabels ?? Is it "that NOT have $GmailHaveLabels"? And: Is there any better way to address the \ALL-Folder? I can use "-x \All" to exclude that folder, but it looks like I can't use "-m \All" to select that folder. We're a little bit in hurry since Google will stop its service this weekend. Any fast help would be appreciated.

Sieve, multiple addresses, and variables
by Andrew Sullivan 08 Apr '15

08 Apr '15

Hi, I have another sieve question, this time about setting variables. I join a lot of mailing lists at ietf.org. I thought it'd be handy to filter these all into a common folder and then into individual folders, without having to configure each mailing list independently. So wrote this (this is just a part, obviously): require ["envelope", "variables", "date", "fileinto", "mailbox" ]; if address :is :domain "to" "ietf.org" { if address :matches :localpart "to" "*" {set "lopart" "${1}";} } elsif address :is :domain "cc" "ietf.org" { if address :matches :localpart "cc" "*" {set "lopart" "${1}";} } else {set "lopart" "generic-list-box";} fileinto :create "ietf.${lopart}-in"; stop; } Now, this works, unless someone sends a To: line like this: To: ajs(a)crankycanuck.ca, listname(a)ietf.org The problem in that case is that you _do_ get a match, but the bit "if address :matches :localpart "to" "*" {set "lopart" "${1}";}" ends up putting this in a mailbox ietf.ajs-in, when what is the mailbox ietf.listname-in. I thought that allof(if address :matches :localpart "to" "*", address :matches :localpart "to" "*") {set "lopart" "${1}";}, would solve this, but it doesn't seem to. The localpart matching catches the ajs(a)crankycanuck.ca address anyway, which surprised me. Am I dim, am I not understanding something about how to do this, or is this really impossible? Thanks, A -- Andrew Sullivan ajs(a)crankycanuck.ca

Need a bit of help with the antispam plugin
by Anthony Papillion 08 Apr '15

08 Apr '15

Hello Everyone, I'm running the antispam plugin on Dovecot 2.0.19 on Ubuntu Server 14.04 and I can't seem to get it to work. In the IMAP section of dovecot.conf I have the following lines: protocol imap { mail_plugins = $mail_plugins imap_quota imap_acl antispam # mail_plugins = $mail_plugins imap_quota imap_acl imap_client_workarounds = tb-extra-mailbox-sep # Maximum number of IMAP connections allowed for a user from each IP address. # NOTE: The username is compared case-sensitively. # Default is 10. # Increase it to avoid issue like below: # "Maximum number of concurrent IMAP connections exceeded" mail_max_userip_connections = 20 plugin { antispam_debug_target = syslog antispam_verbose_debug = 1 antispam_backend = pipe antispam_trash = Trash antispam_spam = Junk antispam_pipe_program_spam_arg = --spam antispam_pipe_program_notspam_arg = --ham antispam_pipe_program = /usr/bin/sa-learn antispam_pipe_program_args = --username=%Lu } } For some reason, when I try to move something to Junk, I get the following in my syslog: Mar 31 18:27:16 anonymail imap: antispam: plugin initialising (2.0-notgit) Mar 31 18:27:16 anonymail imap: antispam: verbose debug enabled Mar 31 18:27:16 anonymail imap: antispam: "Junk" is exact match spam folder Mar 31 18:27:16 anonymail imap: antispam: no unsure folders Mar 31 18:27:16 anonymail imap: antispam: "Trash" is exact match trash folder Mar 31 18:27:16 anonymail imap: antispam: pipe backend spam argument = --spam Mar 31 18:27:16 anonymail imap: antispam: pipe backend not-spam argument = --ham Mar 31 18:27:16 anonymail imap: antispam: pipe backend program = /usr/bin/sa-learn Mar 31 18:27:16 anonymail imap: antispam: pipe backend program arg[0] = --username=anthony(a)cajuntechie.org Mar 31 18:27:16 anonymail imap: antispam: pipe backend tmpdir /tmp Mar 31 18:27:19 anonymail imap: antispam: mailbox_is_unsure(Junk): 0 Mar 31 18:27:19 anonymail imap: antispam: mailbox_is_trash(INBOX): 0 Mar 31 18:27:19 anonymail imap: antispam: mailbox_is_trash(Junk): 0 Mar 31 18:27:19 anonymail imap: antispam: mail copy: from trash: 0, to trash: 0 Mar 31 18:27:19 anonymail imap: antispam: mailbox_is_spam(INBOX): 0 Mar 31 18:27:19 anonymail imap: antispam: mailbox_is_spam(Junk): 1 Mar 31 18:27:19 anonymail imap: antispam: mailbox_is_unsure(INBOX): 0 Mar 31 18:27:19 anonymail imap: antispam: mail copy: src spam: 0, dst spam: 1, src unsure: 0 Mar 31 18:27:19 anonymail imap: antispam: running mailtrain backend program /usr/bin/sa-learn Mar 31 18:27:19 anonymail imap: antispam: running mailtrain backend program /usr/bin/sa-learn Mar 31 18:27:19 anonymail imap: antispam: running mailtrain backend program parameter 1 --username=anthony(a)cajuntechie.org Mar 31 18:27:19 anonymail imap: antispam: running mailtrain backend program parameter 2 --spam Mar 31 18:27:21 anonymail imap: antispam: run program failed with exit code -1 This is probably a permissions issue but I'm not able to debug it.

can't create folders under shared mailbox's INBOX

ACL syntax for setting specified folders within Maildir/ read-only for owner
by kepa 08 Apr '15

08 Apr '15

Hi, I have dovecot (2.2.16, see dovecot -n at end) installed to /opt on CentOS 6 for access on a local network. I would like to create an archival mail account which will reduce the primary account file size and still make older emails easily accessible. How can I set specified folders in this Maildir read-only with ACL? For example, I included this in the dovecot-acl file to specify protected folders in the archives@ Maildir but it did not work: "Email 2013/*" user=archives lrs "Email 2014/*" user=archives lrs Also tried this on folders without spaces with no success (the folders were still delete-able by the user via the Thunderbird client). Each "Email..." folder has several child folders that should also be read-only. BTW, what is the maximum size for a Maildir that Dovecot can comfortably handle? Thanks!

Dovecot keeps creating info files in mail directory instead of home
by Jeffrey 'jf' Lim 08 Apr '15

08 Apr '15

I've been trying to troubleshoot this for a while now, and I'm really at a loss. My userdb is set up correctly to return home, and mail, and a test with 'doveadm user' verifies this: # doveadm user user@domain field value uid 1000 gid 1000 home /var/domain/user mail maildir:/var/mail/user@domain I've reloaded, restarted, stopped and started dovecot again - and even deleted the info files in the mail directory just to be sure - but each and every time I log in with imap, dovecot recreates the files again (dovecot.index.log, dovecot-uidlist, etc.) in the mail directory instead of home. I've even made sure just in case that the home directory is accessible to all, and chmod 777, but nothing gets created there. And I dont get any errors at all in the logs. I'm on the latest version (2.2.16). -jf -- He who settles on the idea of the intelligent man as a static entity only shows himself to be a fool.

Authentication with Samba using Kerberos fails
by Justin Clacherty 08 Apr '15

08 Apr '15

Hi, I've been having some problems getting GSSAPI authentication going against a samba (4.2) server and am hoping someone can point me in the right direction. I've searched through Google and haven't managed to find a solution yet. I followed the config instructions at http://wiki2.dovecot.org/Authentication/Kerberos and run through the testing. Testing from the server with telnet does as expected i.e. I get the "+" after I try "a authenticate GSSAPI". However, when I go to test from Thunderbird on while logged in on a Windows PC joined to the domain authentication fails and I see the following in mail.log (I'm running Ubuntu 14.04.2 LTS).

Deleting empty folders
by Samuel Williams 07 Apr '15

07 Apr '15

So, along with the problem of lots of folders ending in 1 1 1 1, I'd like to have a strategy to delete these. I was trying to understand if it is possible to use http://linux.die.net/man/1/doveadm-expunge to delete empty folders, but without also deleting messages? Is this possible and if so what is the syntax? Kind regards, Samuel

What to read about interactions
by Andrew Sullivan 07 Apr '15

07 Apr '15

Hi, TL;DR: I am having a hard time synthesizing the information I need out of the website/wiki documentation, and google isn't turning up what I need, so I'm looking for advice on what I should read next to understand the way aliases, dovecot's lmtp, and pigeonhole work together. Details below. I've been using dovecot happily for some years, but in a recent migration of my mail server I set up something that I think will be slightly easier to maintain. I now have a single (in my case postgres) database backing all user names and so on, with postfix relying on dovecot auth for user validation and delivery. I have the usual anti-spam machinery in there, and have started using the (for me new) pigeonhole implementation of sieve. (My old mail system was built around the earlier dovecot implementation, and while I've patched it over time it's really pretty creaky.) On the whole, this all seems very nice, but I'm having a hard time understanding the details of what interacts with what other bits when. In particular, my mail system is known by several different names, and I thought it'd be much handier to have everything land in one real mailbox, since I could sort the inbound mail into different mailboxes without a lot of trouble using seive. This has turned out to be slightly trickier than I thought it ought to be (procmail is in some ways easier), and I've come to the conclusion that I don't have a strong foundation in exactly how this is supposed to work. Apart from reading the code (which would probably at this point be hard enough for me so as to make it impossible), are there things I ought to read to understand this better? I've read the seive RFCs, but while that gives me a clue about what ought to happen protocol-wise, it isn't helping me at all to understand the interaction among the different subsystems so that I can see clearly how different parts of the delivery chain are interacting. I'm sure there's some crucial bit of, "Everyone knows that," that I've overlooked, and I thought it would be better to ask for the FM than just to read randomly until I stumbled on it. Thanks, A -- Andrew Sullivan ajs(a)crankycanuck.ca

If you see, some folders got strange names. 41943652 4.0K drwx------ 3 vmail vmail 4.0K Mar 25 10:42 INBOX 1 42205306 4.0K drwx------ 3 vmail vmail 4.0K Mar 25 10:46 INBOX 1 1 42336882 4.0K drwx------ 3 vmail vmail 4.0K Mar 25 10:48 INBOX 1 1 1 42337295 4.0K drwx------ 3 vmail vmail 4.0K Mar 25 10:49 INBOX 1 1 1 1 42598861 4.0K drwx------ 3 vmail vmail 4.0K Mar 25 10:51 INBOX 1 1 1 1 1 42730114 4.0K drwx------ 3 vmail vmail 4.0K Mar 25 10:54 INBOX 1 1 1 1 1 1 42730261 4.0K drwx------ 3 vmail vmail 4.0K Mar 25 10:57 INBOX 1 1 1 1 1 1 1 42730276 4.0K drwx------ 3 vmail vmail 4.0K Mar 25 10:57 INBOX 1 1 1 1 1 1 1 1 42730291 4.0K drwx------ 3 vmail vmail 4.0K Mar 25 10:58 INBOX 1 1 1 1 1 1 1 1 1 42730306 4.0K drwx------ 3 vmail vmail 4.0K Mar 25 10:59 INBOX 1 1 1 1 1 1 1 1 1 1 42730321 4.0K drwx------ 3 vmail vmail 4.0K Mar 25 11:00 INBOX 1 1 1 1 1 1 1 1 1 1 1 42730336 4.0K drwx------ 3 vmail vmail 4.0K Mar 25 11:01 INBOX 1 1 1 1 1 1 1 1 1 1 1 1 42730351 4.0K drwx------ 3 vmail vmail 4.0K Mar 25 11:02 INBOX 1 1 1 1 1 1 1 1 1 1 1 1 1 42730366 4.0K drwx------ 3 vmail vmail 4.0K Mar 25 11:03 INBOX 1 1 1 1 1 1 1 1 1 1 1 1 1 1 42730381 4.0K drwx------ 3 vmail vmail 4.0K Mar 25 11:04 INBOX 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 42730400 4.0K drwx------ 3 vmail vmail 4.0K Mar 25 11:05 INBOX 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 and so on.....
