[Dovecot] Auth worker max line size
by Emmanuel Dreyfus 09 Sep '12

09 Sep '12

Hello I have been playing with some exotic authentication scheme with Dovecot and PAM. That involves sending really large base64 encoded data as the IMAP password, and I have hit a line limit in Dovecot, with AUTH_WORKER_MAX_LINE_LENGTH set to 1024. This limit is especially frustrating since other parts of the software use much larger limits: MAX_INBUF_SIZE 4096 MAX_IMAP_LINE 8192 AUTH_CLIENT_MAX_LINE_LENGTH 8192 I had to make the patch attached below to get my authentication working. I can live with this local patch, but given the much more liberal limits of MAX_INBUF_SIZE at 4096 makes we wonder if this 1024 limit on AUTH_WORKER_MAX_LINE_LENGTH could not be a bug. Or is there a security concern at using more than 1kB? Opinions?

[Dovecot] Can't connect to auth server
by Phill Edwards 13 Feb '11

13 Feb '11

I'm trying to phase out procmail and move to dovecot-sieve instead. It ain't proving easy. I'll describe my setup: - Centos 5.2 box with dovecot 1.1.4 and dovecot-sieve 1.1.6 from ATrpms. - A single user account is used to store all our email (the account is called maildb). - Getmail is being used to fetch the email from various ISP mailboxes. I want to deliver mail to different folders in maildb's Maildir/ depending on who the email is addressed to (the procmail recipes currently do that). - Getmail destination section looks like this: [destination] type = MDA_external path = /usr/libexec/dovecot/deliver arguments = ("-d", "maildb") allow_root_commands = true - When I run getmail I get this error in dovecot.log: deliver(maildb): May 04 22:15:26 Error: Can't connect to auth server at /var/run/dovecot/auth-master: No such file or directory It's true that I don't have a file called auth-master. I guess I should have but until I started this dovecot-sieve work it was never a problem. I have no idea what that file should look like. As I installed from binary RPMs I would have thought one would have come with the install. Can anyone help? Regards, Phill

[Dovecot] Capability COMPRESS implemented?
by Ed W 15 Feb '10

15 Feb '10

Hi, I just read that http://tools.ietf.org/html/rfc4978 ..is being implemented in Thunderbird 3. This is great news! It's been a long time since we last discussed this and I don't think it's currently implemented in Dovecot, but since Cyrus just added it, any chance of getting support in Dovecot please? (Fastmail seems to be supporting this effort) On a similar note we had a previous thread about supporting TLS deflate - any chance you could investigate this again and add support on the Dovecot side so at least it would be feasible to submit a bug fix on the Thunderbird side? (It looked like a one liner change back when we last discussed it?) Thanks Ed W (Obviously for those looking for an external high performance compressor you can use our compressing email proxy from http://www.mailasail.com ...)

[Dovecot] Dovecot + DRBD/GFS mailstore
by Guy 26 Sep '09

26 Sep '09

Hi guys, I'm looking at the possibility of running a pair of servers with Dovecot LDA/imap/pop3 using internal drives with DRBD and GFS (or other clustered FS) for the mail storage and ext3 for the root drive. I'm currently using maildrop for delivery and Dovecot imap/pop3 with the stores over NFS. I'm looking for better performance but still keeping the HA element I have now with shared storage over NFS. Has anyone had experience with a setup like the one I'm suggesting? What was performance like with Dovecot using GFS? Thanks Guy -- Don't just do something...sit there!

[Dovecot] Dovecot broken with newer OpenSSL
by Brad 28 Jul '09

28 Jul '09

After updating my system from OpenSSL 0.9.8j to 0.9.8k Dovecot has stopped functioning properly with TLS sessions. The version of Dovecot does not seem to matter as I tried 1.1.11 - 1.1.14. Other programs using SSL/TLS such as Postfix and lightty still work fine when built with the newer release of OpenSSL. The IMAP client doesn't matter. For the time being I have gone back to .13 linked against older OpenSSL. In the logs I see messages like the following... dovecot: Apr 16 23:12:18 Info: imap-login: Disconnected (no auth attempts): rip=2001:470:b01e:3:216:41ff:fe17:6933, lip=2001:470:1d:8c::2, TLS handshaking: Disconnected -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.
