[Dovecot] performance problems with IMAPS
by Linda Walsh 11 May '11

11 May '11

I've noticed this before and wasn't sure of the problem -- sending large files from FF. I tracked it down, and the problem is in dovecot when it is saving the mail to my 'Record' (Outbox)... It's saving the file in tiny chunks.... Looking at a few, I see: 4148 bytes 2116 bytes 1604 bytes 692 bytes The latency is killing it. I see the TCP window size being as high as 17069 with 7678 being common. The sendmail latency isn't spectacular, but at least uses ~64K packets. So wazzup with dovecot? I don't recall this being so much an issue with the old uwash imaps, but then it's been a while since I've used it and maybe my files weren't as large. But it can take several minutes to save a file to a record file that takes <1 second over network CIFS. Anyway to up the size of minimum packet size to 128K or more? Ideal packet size on my network is about 16MB under CIFS...with benefits seen even using 256MB packet sizes.... Is there a place to tune this that I don't know about? Thanks....

[Dovecot] Dovecot 1.2.x passwd and shadow auth w/ PAM
by Steven King 11 May '11

11 May '11

I'm trying to get authentication to work without PAM and just use the standard shadow and passwd files. auth default { userdb passwd { } passdb shadow { } } This seems to be valid code to use /etc/passwd and /etc/shadow. My linux distro is using Salted MD5. Though Dovecot keeps telling me that authentication failed. It doesn't give me any error messages regarding the config. Any ideas? -- Steve King Senior Linux Engineer - Advance Internet, Inc. Cisco Certified Network Associate CompTIA Linux+ Certified Professional CompTIA A+ Certified Professional

[Dovecot] Dovecot using FTS solr or Squat when searching multiple fields.
by duonut 10 May '11

10 May '11

Hi Im using dovecot 1.2.16 with Solr setup for FTS. When searching a single field such as subject Dovecot will use the solr index. When searching multiple fields such as subject and body it does not use the index and uses the standard built in search which takes much longer. Is there any way to get Dovecot to use the solr or squat index when searching multiple fields? -- View this message in context: http://old.nabble.com/Dovecot-using-FTS-solr-or-Squat-when-searching-multip… Sent from the Dovecot mailing list archive at Nabble.com.

[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!!
