[Dovecot] proxying user logged in with master user
by Miguel Cabeça 06 Jul '11

06 Jul '11

Hello, I'm running dovecot 1.2.15 and I'm having a problem proxying a user to another host, when this user is logged in with a masteruser. I have two dovecot servers configured to serve half of the users locally and to proxy the other half to the other host. Proxying is done using the masteruser feature (username*proxy) and it works as expected as the following test shows: # nc localhost 143 * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE STARTTLS AUTH=PLAIN AUTH=LOGIN AUTH=GSSAPI] Dovecot ready. 01 LOGIN ist90001 password_for_ist90001 01 OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS MULTIAPPEND UNSELECT IDLE CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS QUOTA] Logged in ^C And the corresponding log entry: Jul 6 13:10:06 mail1 dovecot: imap-login: proxy(ist90001): started proxying to X.Y.Z.W:143/ist90001*proxy: user=<ist90001>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured Jul 6 13:10:09 mail1 dovecot: imap-login: proxy(ist90001): disconnecting 127.0.0.1 The ist90001 is proxied to the other host as expected and as configured. The problem occurs when I try to use another masteruser to log into the server: # nc localhost 143 * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE STARTTLS AUTH=PLAIN AUTH=LOGIN AUTH=GSSAPI] Dovecot ready. 01 LOGIN ist90001*super password_for_super_masteruser 01 OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS MULTIAPPEND UNSELECT IDLE CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS QUOTA] Logged in ^C But this time the user isn't proxied to the other host. Instead he is logged in this host: Jul 6 13:11:14 mail1 dovecot: imap-login: Login: user=<ist90001>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured Jul 6 13:11:16 mail1 dovecot: IMAP(ist90001): Connection closed bytes=0/292 Is this the intended behavior or a bug? I was expecting the user to be logged in with the password of the super masteruser, and then be proxied to the other host as it happens when the user is logged in with it's own password. I can provide any configuration details if needed. Best Regards Miguel Cabeça

[Dovecot] Converting from qpopper mbox to dovecot maildir
by list＠airstreamcomm.net 05 Jul '11

05 Jul '11

We have an older mail server using qpopper and the mbox format which we need to update to dovecot and maildir format. I have read through the docs on migrating from mbox to maildir, as well as a few nuggets on how to migrate from qpopper to dovecot, and I was wondering if I could get some suggestions on best practices for this specific migration. Would the built in dovecot conversion plugin be a viable method to migrate users? We will be migrating to dovecot 2.0.12 from qpopper 4.0.5. Thanks.

Hello, I want to set a uniform quota for each mailbox.

[Dovecot] Dovecot 2.0.13 problem with LMTP
by Innocenzi, Cinzia 05 Jul '11

05 Jul '11

Hello, we have dovecot 2.0.13 installed in our RHEL5 servers. We use dovecot as a lmtp proxy on the front end mail relays and dovecot for back end lmtp/pop/imap. All our servers have RHEL5.6 64-bit and dovecot 2.0.13 installed, and the back end has also an ext3 mbox file-system mounted. Sometimes we have mails that get stuck on our postfix queue with the following error: Remote server not answering (timeout in DATA input) (in reply to end of DATA command) In our logs we only see the fact that the connection times out after 1 minute and gets disconnected: Jun 22 11:56:53 back-end dovecot: lmtp(3256): Connect from a.b.c.d Jun 22 11:57:53 back-end dovecot: lmtp(3256): Disconnect from a.b.c.d: Connection closed Jun 22 11:56:53 front-end dovecot: lmtp(16397): Connect from a.b.c.d Jun 22 11:57:53 front-end dovecot: lmtp(16397): Disconnect from a.b.c.d: Disconnected for inactivity We've tried to recalculate the mbox quota using "doveadm quota recalc -n ..." command and flushed our mail queue, but the mail still gets stuck on the postfix queue with the same error. It doesn't happen for every single mail, it's random. I'm attaching the output of dovecot -n for both servers. Can you please help us?

[Dovecot] imap idle and concurrent connections
by Wolfgang Rosenauer 05 Jul '11

05 Jul '11

Hi, in my testing dovecot (1.2 in that case) seems to not notify all idling clients about new "recent" mails but only one of them. The others get usually a message about the new number of mails after some time but never recent ones. Only one client gets notified about a new mail. Is that a known issue or something which might be configuration specific? Wolfgang

Thanks, it's working after upgrading. As you adviced, I wanted to check if the latest version works before posting exim bug report.

See: http://www.postfix.org/VIRTUAL_README.html http://www.postfix.org/ADDRESS_CLASS_README.html The "upgrade" advice is very good. You should not be starting out with something so long past the end of its support. Follow up on Postfix issues on the Postfix list. However, your issue will probably be solved with some time in the documentation. -- Offlist mail to this address is discarded unless "/dev/rob0" or "not-spam" is in Subject: header
