20 Oct '10

We have custom plugins for squirrelmail which use thread orderedsubject, but according to capabilities dovecot only support thread by references algorithm. At present, we are using Courier with this capabilities (two algorithms are implemented). Could we use orderedsubject in dovecot?

[Dovecot] Outlook problem when deleting mails
by Ulf Jaenicke-Rößler 20 Oct '10

20 Oct '10

Hi, I'm seeking advice to solve the following "mystery": I set up an IMAP server on Ubuntu 10.04 (dovecot 1.2.9). It appears to work fine apart from one problem. A colleague is running Outlook 2007 on Vista and sometimes (sometimes very often, sometimes only occasionally) when he wants to delete mails, Outlook hangs for some time (he says about 1, 2 or 3 minutes) until it finally puts out a message box: "The server did not respond to this IMAP command before the connection was terminated" I have activated the outlook-idle workaround, but I learned that this doesn't do anything anymore, right? There's no error message in dovecot's logs. Nevertheless, today I found this around the time the error happened: 2010-10-12 17:13:02 imap-login: Info: Login: user=<user>, method=PLAIN, rip=192.168.100.53, lip=192.168.100.20 2010-10-12 17:13:03 imap-login: Info: Login: user=<user>, method=PLAIN, rip=192.168.100.53, lip=192.168.100.20 2010-10-12 17:15:07 IMAP(user): Info: Disconnected in IDLE bytes=272298/631645 2010-10-12 17:15:07 IMAP(user): Info: Disconnected: Logged out bytes=63/539 2010-10-12 17:15:07 IMAP(user): Info: Disconnected: Logged out bytes=462/47082 What exactly does "Disconnected in IDLE" mean? Could the error be related to the same time stamp? (I'm not yet sure, if it always happens this way if the error occurs) I also found "Disconnected in IDLE" for other users at other times, but no one other complained so far. Maybe, that's because most of the other users use Thunderbird ;-) Is this problem known? What could I do? Best regards Ulf

[Dovecot] (Single instance) attachment storage with single-dbox
by Timo Sirainen 19 Oct '10

19 Oct '10

Just a note to myself and whoever else cares, should be added to wiki once it has its own page about this: With single-dbox messages can be copied with hard linking. This means that there can be multiple files that point to the same attachment file. The attachment is now deleted only once the mail file's link count drops to zero, so this works fine.. ..until someone goes and starts manually copying files or maybe restoring from backups or whatever, causing the hard links to be replaced with separate files having link count=1, even when there are other files pointing to the same attachment file. Now deleting this one mail will delete the attachment too early. I can't think of any other reasonable way to handle this though, so unless someon has some great ideas, I think the solution is to simply add enough warnings that message store shouldn't be accessed directly. Maybe add some import/export commands to doveadm which can be used to add a bunch of mails to storage without doing it directly on filesystem.

[Dovecot] gssapi problems (postfix sasl through dovecot, dovecot imap working fine)
by Trever L. Adams 19 Oct '10

19 Oct '10

Thanks to Timo, I have solved all but one of my problems. For back ground, I am using Samba4 as an AD. I have the userdb working from LDAP just fine and kerberos authenetication for dovecot's IMAP server working fine. The problem is using dovecot's SASL with postfix. I also have plain/login working in imap and smtp. Both use pam_krb5 through pam to authenticate clients that don't have kerberos, and for now smtp. When trying to do smtp kerberos, I get the following: postfix/smtpd[6197]: warning: CLIENT_FQDN[CLIENT_IP]: request longer than 2048: AUTH GSSAPI ... dovecot: auth: Debug: client in: AUTH#0111#011GSSAPI#011service=smtp#011nologin#011lip=SERVER_IP#011rip=CLIENT_IP#011secured#011resp=<hidden> dovecot: auth: Debug: gssapi(?,CLIENT_IP): Obtaining credentials for smtp@MAILSERVER_FQDN dovecot: auth: gssapi(?,CLIENT_IP): While processing incoming data: Unspecified GSS failure.

Any help would be greatly appreciated. I have made sure that the file has proper permissions. I have regenerated the smtp cert making suer the password is accurate. I have done everything I know to try. The only thing that I am guess remains is something is broken with Thunderbird's kerberos setup for smtp. Thank you very much, Trever

[Dovecot] Imap Logout format
by Antonio Perez-Aranda 19 Oct '10

19 Oct '10

He all, I'm migrating a big system from Courier to Dovecot and we have a custom analyzer logger system to Courier logs. We have got the very similar specs on IMAP LOGIN log, but I can't get the Logout format. Courier write like that: ... imapd: LOGOUT, user=luism.martinez, ip=[::ffff:127.0.0.1], headers=0, body=0, rcvd=131, sent=632, time=0 ¿Is there any Variables on imap_logout_format to get headers, body and time vars?

[Dovecot] disable zlib via config to allow per mailbox compression level
by Kui Zhang 19 Oct '10

19 Oct '10

Hello Dovecot v2.0.5 zlib_save_level = 6 # 1..9 zlib_save = gz # or bz2 Is there a config option to disable zlib, even if above config are in place? If so please provide an example. If no, would it be possible to add one? Like if zlib_save_level = 0 disable zlib. So one can configure per mailbox compression level via sql database. KuiZ Thanks
