[Dovecot] Thunderbird slow in talking with dovecot IMAP AND to sendmail
by Linda Walsh 03 Nov '11

03 Nov '11

I'm trying to find out what's causing this slowdown -- it's INTOLERABLE.... over 1 minute and less than 1% done. (400MB file)... After trying 3 times, I gave up and logged in using X to the server and ran Tbird from there.... Mail sent out in < 1 minute, though the copy to dovecot took about 50% longer. So... I looked at the network trace. and everyfrackin' body was using 4K packet sizes (at the application level!, the window size on TCP was over 64K...but no one was using it)....especially galling with my network's MTU at 9K, BTW, because small packets are really bad on a 1Gb network. sendmail -- 4K, dovecot /ssl, 4K... wazzup .. is t-bird forcing this, or is there some ssl requirement? but it can't just be ssl -- as it's talking to sendmail on port 25 unencrypted (it's a local net anyway)... I could see the entire binary going out in text form... 1 line at a time...a "C" line in sendmail, with lens of 4096...is that some max? I don't see it in the sendmail.cf files...wanted to see if anyone knew of dovecot restrictions that might limit packets to 4k, before I lamblasted the thunderbird people for another act of mindless stupidity (the first being when they decided to cache all your IMAP store on every local client in the client's ROAMING profile...*brilliant*!!!... sides, if I wanted it on local I would have set 'store on local', but in TB3, they know better and change that for me... Something about them being too stupid to use indexing and searching on an imap server? Maybe I just imagined hearing that...

[Dovecot] dsync should sync sieve-dirs to!
by Peer Heinlein 01 Nov '11

01 Nov '11

Having dsync to make backups from existing mail-spaces, it would be nice to make dsync syncing the sieve-dirs too. -Otherweise backups aren't complete...

[Dovecot] Problems with permissions on mail_location
by Vlad 31 Oct '11

31 Oct '11

Hi, All! I have 2.0.beta6 (3156315704ef) Trying to set up Dovecot with virtual users. mail_uid=mail mail_gid=mail mail_location = maildir:/var/mail/%n /var/mail owner is mail:mail, permissions is 777 From error log: Oct 31 13:34:17 imap(test): Error: user test: Initialization failed:Initializing mail storage from mail_location setting failed: mkdir(/var/mail/test) failed: Permission denied (euid=8(mail) egid=12(mail) missing +w perm: /var/mail, euid is not dir owner) but /var/mail owner is mail:mail (same the euid, egid). In what may be the problem? (With full rights to the directory dovecot does not want to write it :-\ ) If I change /var/mail to /tmp/mail (for testing), then everything works fine, dovecot can write to this directory. But if i create /test/mail, or /mail with chmod 777 and chown mail:mail - again the same error :-( -- С уважением, Vlad mailto:vladsol@ukr.net

[Dovecot] dovecot creating literal %d/%n/ folders
by sean darcy 31 Oct '11

I have a virtual user test1. cat /etc/dovecot/users test1@<mydomain>:{PLAIN}test1pass:504:504::/home/vmail/%d/%n catchall@<mydomain>:{PLAIN}password:504:504::/home/vmail/%d/%n @<mydomain>:{PLAIN}password:504:504::/home/vmail/<mydomain>/catchall test1@example.com:{PLAIN}test1pass:504:504::/home/vmail/%d/%n ls /home/vmail/%d/%n/mail cur dovecot.index.cache dovecot.index.log dovecot-uidlist dovecot-uidvalidity dovecot-uidvalidity.4eab20a7 new tmp and mail to test1@<mydomain> goes into this %d/%n folder. In fact dovecot created the folder - at least I didn't. from dovecot-info.log Oct 28 17:43:11 auth: Debug: master in: USER 4 test1@<mydomain> service=lmtp Oct 28 17:43:11 auth: Debug: passwd(test1@<mydomain>): lookup Oct 28 17:43:11 auth: Info: passwd(test1@<mydomain>): unknown user Oct 28 17:43:11 auth: Debug: passwd-file(test1@<mydomain>): lookup: user=test1@<mydomain> file=/etc/dovecot/users Oct 28 17:43:11 auth: Debug: master out: USER 4 test1@<mydomain> uid=504 gid=504 home=/home/vmail/%d/%n Oct 28 17:43:11 lmtp(4533, test1@<mydomain>): Info: l6DnLacgq061EQAABoXEcA: msgid=<4EAB21EC.9070905(a)gmail.com>: saved mail to INBOX I would have expected dovecot to expand this to /home/vmail/<mydomain>/test1. Or are the %u %d variables only expanded in certain files? sean

[Dovecot] Manage dovecot maildir on multiple servers
by Arlin 31 Oct '11

31 Oct '11

Any suggestions on how to implement dovecot maildir on multiple servers. Does this required independent installation of Dovecot on each servers, or a single instance of Dovecot with shared MailDir would serve the purpose? Thanks, Arlin

[Dovecot] how to tell dovecot v2.0.1 not to listen on port 143
by Lars Täuber 28 Oct '11

28 Oct '11

Hi. Sorry for breaking this thread, but I just subscribed from a different address. I made a mistake. I didn't mean »imaps« but »imap2« How can I configure dovecot not to listen for imap connections on port 143. I want dovecot to listen only on port 993. And ssl = required is already set. So this is not the right solution. I just comemnted the whole inet_listener imap {...} section out. But this seems to be some kind of default setting. I tried to set: inet_listener { address = none } I tried to leave the address variable blank. But no succes. Good night Lars

[Dovecot] Quotas with Maildir and mdbox
by Dr Matthew Williams 28 Oct '11

28 Oct '11

Hello, We use LDAP to store our Maildir++ quota information for our Maildir mailboxes. I notice in the documentation that only SQL and flat files are supported by the dictionary quota if I want to use quota with mdbox? Are there any plans to allow LDAP to be used as the store?
