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

27 Nov '13

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

[Dovecot] Permissions problems

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

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

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

27 Nov '13

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

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

26 Nov '13

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

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

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

26 Nov '13

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

[Dovecot] 2.2.9
by Nick Edwards 26 Nov '13

26 Nov '13

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

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