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").

FYI: Some 'fun' unlinks with random memory space references
by Jeroen Massar 10 Apr '15

10 Apr '15

Hola, Dovecot: 2.2.16 (6bde7868cffd) That is the rename-it 2:2.2.16-1~auto+43 edition.

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.
