[Dovecot] Dovecot Maildir ownership/permission problem
by ikevinjp 10 May '11

10 May '11

Hi, I have successfully configured Dovecot+Postfix+SSL/TSL and it seems that everything is working except that I have a permission problem with the items under Maildir. When a mail is first delivered into a user, Postfix automatically creates the Maildir using the user's account and group. It is readable only by the user. This seems to be the correct setting for me, as only the user could read his/her own mails. However, Dovecot gave an error saying the Maildir is inaccessible and shows that is a permission problem. I changed the chmod to 777 and Dovecot worked (temporarily solution). And, it created additional items under that folder under a "mailman" user (which I specified in the configuration using mail_uid and mail_gid) - Note: it does not work if I do not set these "mail_uid" and "mail_gid" settings. I think what I would like is to make Dovecot access each individual's mailbox using the user's own account and group. How do I do this? I am using Passwd-file scheme. --- My dovecot.conf: mail_uid = vmail mail_gid = vmail listen = 192.168.1.2 protocols = imap pop3 ssl = yes ssl_cert = </usr/local/etc/sslcerts/server.crt ssl_key = </usr/local/etc/sslcerts/server.key mail_location = maildir:/home/%n/Maildir maildir_copy_with_hardlinks = yes auth_mechanisms = cram-md5 service auth { unix_listener auth-client { group = postfix mode = 0660 user = postfix path = /var/spool/postfix/private/auth } user = root } passdb { driver = passwd-file args = username_format=%n /usr/local/etc/dovecot/dovecot.users } log_path = /var/log/dovecot.log --- --- Some entries on my passwd-file would be: username:{CRAM-MD5}efaa8bbe8fb0d28a55f7595c3420791990f25cc536f0e23c46cb392cb2b058e2:1001:1001::/home/username:: peter:{CRAM-MD5}512b3e383d95a191d9481e1914cc4caad70cd57029706ec5c3db8ef3039ef405:2001:2001::/home/peter:: --- Any advice is greatly appreciated.

[Dovecot] Dovecot very slow on a mailbox with > 700 IMAP Folders
by Becker, Ronny 10 May '11

10 May '11

Hello, I am using Dovecot 1.2.9 on a 32bit on Ubuntu 10.04.2 LTS. We got one user who uses folders in an "exessive" way. He has got 704 subscribed folders. That means about nearly 3000 folders on the filesystem. Since ~ a week the user couldn't work because of timeouts when connecting to Dovecot (IMAP). Thunderbird doesn't show any folders - timeout - the webmail System (Groupoffice) only presents the INBOX. I did some debugging and found that a lsub "" "*" that is used by Thunderbird takes > 5 minutes. Thunderbird disconnects after ~1 Minute showing the timeout. I entered the command directly via port communication. So this is no clientside problem. But there is no error message or something else in any logs. I did some debugging with strace, too. It's about 22MB only for running the lsub command !? The Mailbox size is about ~2.2GB, so this should be no problem. The maximum subfolder level is about 13 - could this be a problem? You can find the structure (simply shown) attached. Thanks for any help!!

Hi, Yes know, I know, that ANY OUT of SPACE problem is SPECIALLY administrator's problem and please check my previous answer ... Out of space on the disk is my problem, but I want to know, why postfix receive message to it's spool (another partition - lot of space) and when postfix uses dovecot to deliver message to the inbox, where is NO space, why message is lost and removed from qmgr. thanks a lot :-) Peter > > On 5/9/2011 10:37 AM, Petr Svacina wrote: >> Hi, >> >> Please I have a question: >> >> If my server is out of space (disk full) and the postfix is LDA, the new messages a deffered or refused,so postfix send 450 to sender ... >> But When I use dovecot (1.2.16) like LDA, postfix accept message (even there is no space), forward to dovecot, dovecot REFUSE the message and message is lost ! >> >> How can I solve this ?
