[Dovecot] Dovecot 2.0.rc3 Capability response
by Christian Affolter 04 Aug '10

04 Aug '10

Hi I have a question regarding the IMAP CAPABILITY command behavior of Dovecot 2.0.rc3. While connecting to a Dovecot 1.2.4 server and requesting the supported capabilities, Dovecot returns all capabilities: * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE STARTTLS AUTH=PLAIN] Dovecot ready. a1 CAPABILITY * CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE SORT THREAD=REFERENCES THREAD=REFS MULTIAPPEND UNSELECT IDLE CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH ACL RIGHTS=texk QUOTA AUTH=PLAIN AUTH=CRAM-MD5 a1 OK Capability completed. Doing the same on 2.0.rc3, will return only a limited set of supported capabilities: * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE STARTTLS AUTH=PLAIN] Dovecot ready. a1 CAPABILITY * CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE STARTTLS AUTH=PLAIN a1 OK Capability completed. However after a user has logged in, Dovecot 2.0.rc3 returns all supported capabilities: * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE STARTTLS AUTH=PLAIN] Dovecot ready. a1 login user(a)example.com pass a1 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 ACL RIGHTS=texk] Logged in a2 CAPABILITY * 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 ACL RIGHTS=texk a2 OK Capability completed So what's the idea behind the change of this behavior? Is it planned to support different capabilities per user in the future? The reason behind my question is, that the Open-Xchange IMAP client implementation relies on the presence of the ACL capability presented before the actual login took place. Thanks for any clarifications. Regards Christian

[Dovecot] OT dovecot w/postfix, mysql , postfix does unnecessary lookups
by Noel Butler 04 Aug '10

04 Aug '10

I know this unnecessary lookups question is really a postfix one, but I'm curious if anyone else sees the behaviour of postfix continuing looking up users after it clearly have got its answer that it is "not a local domain" response. (this msg is an extract from what I sent to WV some time ago, with him showing absolutely no interest, I got bored tonight so thought I'd throw it on this list since the question remains valid today) 30 Query SELECT 1 FROM virtual_domains WHERE name='example.net' AND active ='1' 31 Query SELECT destination FROM view_aliases WHERE email='someuser(a)example.net' Should that not have ended its lookups at Q30 and not gone on to ask Q31 which it now knows is not local? Secondly, it seems to do "double lookups" of destination and email before it gets to dovecots deliver, has anyone else ran a log on mysql and seen same? I'm trying to work out why, since it already has its answer by Q54 and Q55, it is doing Q56 and Q57, which seem pointless... 54 Connect 54 Query SELECT destination FROM view_aliases WHERE email='laura(a)example.com' 55 Connect 55 Query SELECT email FROM view_users WHERE email='laura(a)example.com' 56 Connect 56 Query SELECT destination FROM view_aliases WHERE email='laura(a)example.com' 57 Connect 57 Query SELECT email FROM view_users WHERE email='laura(a)example.com' So, it to me appears postifx does more work then it needs too since it already knows the answer, I consider this a flaw in postfix, yet perhaps I am the only one seeing it hence why WV couldnt give a shit. just curious if anyone has noted same or not....

by Henrique Fernandes 04 Aug '10

#dsync -D -vv -u stak(a)nti.uff.br mirror maildir:/CX4/vdomains/ nti.uff.br/stak/mail dsync(root): Fatal: Mail locations must use the same virtual mailbox hierarchy separator (specify separator for the default namespace) My mail.conf *mail_location = mbox:/CX4/vdomains/%d/home/%n/mail:INBOX=/CX4/vdomains/%d/var/spool/mail/%n:INDEX=/tmp/imap-index/%d/%n *What that error means ? Before when i used convert before, it worked as expected. I want to convert my mboxs to maildir. Prefered withoud down time. To do without down time i will do like this. First i convert like i am trying it above, and after i do this, i run once again to see if got any new mail after this, i change in my mysql setting of mail location to /CX4/vdomains/%d/%u/mail/ My mysql settins override the conf file. But firts i have to make the first command work, anyone has any ideias ? []'sf.rique

[Dovecot] AntiSpam Plugin
by Leander S. 04 Aug '10

04 Aug '10

P.S. I just tried it with 1.2.13 as well - still the same issue. Am I doing something wrong, or is this really a bug now!? Best Regards Leander S. Hi, Has anyone got the chance to get this running? I'm permanently getting this Serverbug error ... ;( *"[SERVERBUG] failed to send email"* ... This happens when I try to drag&drop mails from one to the other folder within a IMAP-session. What version of Dovecot must I have to get this plugin working? Or will it generally be broken in upcoming new releases of Dovecot? Best Regards Leander S.

[Dovecot] problem with mail_full_filesystem_access = yes
by Ladislav Pašek 04 Aug '10

04 Aug '10

Hello, I have configured Dovecot 1.2.12 with Postfix 2.6.5 and everything is working fine. But tomorrow I wanted to run IMAP ALCs and from log I found that this plugin is conflicting with parameter mail_full_filesystem_access = yes in my config. But when I set mail_full_filesystem_access = no it stops authorization for postfix with this message: <pasek(a)valbek.cz>: Command died with signal 11: "/usr/libexec/dovecot/deliver" Does anybody know what could be wrong in my config? I've spend a night with it but without success. You can see my Dovecot here: http://www.volny.cz/vykupitel/Pictures/mail/dovecot.conf http://www.volny.cz/vykupitel/Pictures/mail/dovecot-ldap.conf and Postfix here: http://www.volny.cz/vykupitel/Pictures/mail/main.cf http://www.volny.cz/vykupitel/Pictures/mail/master.cf http://www.volny.cz/vykupitel/Pictures/mail/ldap-users.cf http://www.volny.cz/vykupitel/Pictures/mail/ldap-groups.cf Thanks in Advance Ladislav

[Dovecot] Convert plugin
by Egbert 03 Aug '10

03 Aug '10

Hi, I'm trying to convert users from a sendmail server to a postfix/dovecot server. All works fine but one of the last things is to rescue the messages in /var/mail/<user> on the old server. This seems very straitforward using the convert plugin but with the settings from the wiki, nothing happens when the user logs in. Do I need a private namespace for this as suggested elsewhere in the wiki? I experimented with mb2md.pl and that seems to do what we need but having the old mail converted upon login is much more attractive. In that way we hope that we can also find some 'dead' users. TIA Egbert Jan

[Dovecot] Plugin Handle input messages
by Alex Baule 03 Aug '10

03 Aug '10

Hi Timo.... I try to change my plugin to read the input email to increase a header line and one \r\n. But i need help to get this input.... My plugin is based in zlib plugin. In "static int zlib_permail_get_stream" function, have it. if (imail->data.stream != NULL || (_mail->uid == 0 && zuser->save_handler == NULL)) { return zmail->super.get_stream(_mail, hdr_size, body_size, stream_r); } I think this is the line that return the stream that is the stream sent by client. I try to change this line and put inside this IF , a call to my function to handle with the input email from client. But i got some errors about the input part. In other email, Timo said, to get the S and W flags in the email name, i need to intercept the email input from client to dovecot, in this part is done the W and S calculation. Timo, where is the part that i can get the input from client ?

Hi, we're using quota with the maildir backend. When new mail arrives, the quota gets updated. But when mail is expunged, quota stays the same (see imap dialog below). We're using the latest version from hg ( 1.2.13 ).

[Dovecot] Mbox corruption - Inbox beginning with 'FFrom' or 'FrFrom'
by Henri Khou 03 Aug '10

03 Aug '10

Hi, Since the 23rd of March, we encounter mailbox corruption for some users (15 out of 5000) using POP mainly via Thunderbird. Symptoms are : -users can login but fail to receive new mails and fail to read their inbox -Dovecot.log : ar 29 11:00:06 Error: POP3(user_login): Couldn't init INBOX: Mailbox isn't a valid mbox -The mailbox start with either 'FFrom or 'FrFrom' We can temporarily fix the issue by manually editing the mailbox so that it begins with a proper 'From'. For some users, the problem reoccurred after we apply this workaround. I have to mention that this server has been running fine since almost a year with the current hardware and software configuration. Does anybody has an idea regarding this issue?
