[Dovecot] How to achieve: Automove of mails
by Daniel Watts 09 Apr '06

09 Apr '06

Dear All, I was wondering if this is possible: I am using namespaces to support my environment which has legacy mboxes and new maildirs. In it looks like: namespace private { separator = / inbox = yes prefix = location = maildir:/home/virtual/%d/home/%n/Maildir/ } namespace private { separator = / prefix = mail2/ inbox = yes hidden = yes location = mbox:/home/virtual/%d/home/var/spool/mail/%n:INBOX=/home/virtual/%d/var/spool/mail/%n } This basically means that there is a hidden inbox "mail2/INBOX" that the user cannot see but which can referenced and accessed. What I would like is for Dovecot to automatically move all mail (actually only as much as possible within quota limits) in "mail2/INBOX" into "/INBOX" whenever INBOX is checked/expunged. An alternative acceptable solution is to have something that moves mail once it has read. I would then symlink mail2/INBOX as a "New mail" folder. Once user's read their mail it is moved to the standard /INBOX folder. Are either of the above possible natively or do I need to look at something like plugins? Incidently where is the documentation guiding plugin development? I've looked at the website but can't find anything either by browsing or searching. Many thanks, Daniel

[Dovecot] LDAP and prefetch
by Jorgen Lundman 09 Apr '06

09 Apr '06

SunOS pop01.unix 5.10 Generic_118844-26 i86pc i386 i86pc dovecot-1.0.beta3 It is most likely something I am doing wrong, but could someone take a look at why I can not get LDAP prefetch to work? If I define things like this: dovecot.conf: ---------------------------------------------- passdb ldap { args = /usr/local/etc/dovecot-ldap.conf } userdb ldap { args = /usr/local/etc/dovecot-ldap.conf } ---------------------------------------------- dovecot-ldap.conf: ---------------------------------------------- base = uid=%n, o=%d, ou=mail, dc=example, dc=com user_attrs = homeDirectory=home,uidNumber=uid,gidNumber=gid user_filter = (&(objectClass=posixAccount)(mail=%u)) pass_attrs = mail=user,userPassword=password,homeDirectory=userdb_home,uidNumber =userdb_uid,gidNumber=userdb_gid pass_filter = (&(objectClass=posixAccount)(mail=%u)) ---------------------------------------------- This works correctly. Queries LDAP twice, but retrieves home, uid, gid and mail correctly. Authenticates well. If I replace the userdb line in dovecot.conf with: ---------------------------------------------- userdb prefetch { } ---------------------------------------------- It does no longer work. The passdb query is still correct, and it is followed by a second "empty" ldap query (as seen from snoop) with the following errors: Mar 20 15:58:06 pop01.unix dovecot: [ID 474965 mail.info] Dovecot v1.0.beta3 starting up Mar 20 15:58:14 pop01.unix dovecot: [ID 107833 mail.error] auth(default): prefetch(fred(a)uranus.com,172.20.12.12): userdb_uid not returned Mar 20 15:58:14 pop01.unix dovecot: [ID 107833 mail.error] auth(default): prefetch(fred(a)uranus.com,172.20.12.12): userdb_gid not returned Mar 20 15:58:14 pop01.unix dovecot: [ID 107833 mail.error] auth(default): userdb(fred(a)uranus.com,172.20.12.12): user not found from userdb Mar 20 15:58:14 pop01.unix dovecot: [ID 107833 mail.info] pop3-login: Internal login failure: user=<fred(a)uranus.com>, method=PLAIN, rip=172.20.12.12, lip=172.20.12.8 Snoop of failing lookup: LDAP: Operation *[APPL 3: Search Request] LDAP: [Base Object] LDAP: uid=fred, o=uranus.com, ou=mail, LDAP: dc=example, dc=com [snip] LDAP: And *[0] LDAP: Equality Match *[3] LDAP: [Attr Descr] LDAP: objectClass LDAP: [Value] LDAP: posixAccount LDAP: *[3] LDAP: [OctetString] LDAP: mail LDAP: [OctetString] LDAP: fred(a)uranus.com LDAP: *[Sequence] LDAP: [OctetString] LDAP: mail LDAP: [OctetString] LDAP: userPassword LDAP: [OctetString] LDAP: homeDirectory LDAP: [OctetString] LDAP: uidNumber LDAP: [OctetString] LDAP: gidNumber [snip] LDAP: Operation *[APPL 4: Search ResEntry] LDAP: [Object Name] LDAP: uid=fred,o=uranus.com,ou=mail,dc LDAP: =example,dc=com LDAP: *[Partial Attributes] LDAP: *[Attribute] LDAP: [Type] LDAP: uidNumber LDAP: *[Vals] LDAP: [Value] LDAP: 105 LDAP: *[Attribute] LDAP: [Type] LDAP: gidNumber LDAP: *[Vals] LDAP: [Value] LDAP: 200 LDAP: *[Attribute] LDAP: [Type] LDAP: homeDirectory LDAP: *[Vals] LDAP: [Value] LDAP: /export/nfs/mail/com/s/u/ur LDAP: anus/fred/ LDAP: *[Attribute] LDAP: [Type] LDAP: userPassword LDAP: *[Vals] LDAP: [Value] LDAP: {crypt}QAa3SPeYrDARs (its "test", no leak fun here) LDAP: *[Attribute] LDAP: [Type] LDAP: mail LDAP: *[Vals] LDAP: [Value] LDAP: fred(a)uranus.com [snip] TCP: Destination port = 389 (LDAP) LDAP: ----- LDAP: ----- LDAP: LDAP: "" LDAP: TCP: Destination port = 389 (LDAP) LDAP: ----- LDAP: ----- LDAP: LDAP: "" LDAP: Please advice!

[Dovecot] POP (dot) locks
by Christian Balzer 09 Apr '06

09 Apr '06

Hello, just to soothe my paranoia from many years of qpopper usage, which enforces solitary access to a POP mailbox. Only one login per user is possible at the same time and if a session terminates w/o qpopper being properly notified it will remain locked for some time, 30 minutes by default. With dovecot (0.99.10.4) one can login multiple times (using POP, with IMAP of course this comes as no surprise :) and thus I presume this bit from the configuration: --- # Should we create dotlock file even when we want only a read-lock? Setting # this to yes hurts the performance when the mailbox is accessed simultaneously # by multiple processes, but it's needed for reliable reading if no other # locking methods are available. #mbox_read_dotlock = no --- means that if the only other reading accesses to a (mbox style in this case here) mailbox are via other dovecot processes everything will be fine?

Hi there We are trying to move over from 1 IMAP server to another, but the problem is dovecot does not allow .'s in folder names (and we have quite a number of people who do have .'s in their folder names (ie "www.domain stuff") Is there anyway of allowing dovecot to allow .'s in folder names? Thanks Craig Whitmore

[Dovecot] [Fwd: Imap Timeouts]
by Neilw 07 Apr '06

Hi guys, So is there resolution to my query below? Is this a bug in beta3? Thanks. Neil -------- Original Message -------- Subject: Imap Timeouts Date: Wed, 22 Mar 2006 16:56:21 +0200 From: Neil Wilson <neilw(a)dcdata.co.za> To: dovecot(a)dovecot.org Hi guys, I've got a client running 1.0.beta3 on SuSe 9.3 Everything has been running perfectly since it was installed about 6 months ago, but lately they've had issues with email clients not being able to connect to the IMAP server, until they close their clients(Thunderbird & Outlook) and then re-open them. They have roughly 70 users on their network, so it sounds like it could be too many active sessions at once, but I've tried changing a few things in the config, and so far nothing has resolved this. Any help would be appreciated. Regards.

[Dovecot] GSSAPI and virtual Users?
by S. Thias 06 Apr '06

06 Apr '06

Hi, is there a possibility to map login-names to allowed Kerberos-Principals? At the moment GSSAPI-authentication seems to work only if loginname and kerberos-principal are the same, or am I missing something? It would be really great to use GSSAPI-auth with virtual users. Thanks a lot! S. Thias

[Dovecot] Overriding inbox location in passwd-like file
by Václav Haisman 05 Apr '06

05 Apr '06

Hi, I have some real users and some virtual users. The real users use mbox file as their inbox. But I'd like to use Maildir as inbox for the virtual users. (The reason is that I am actually moving some accounts from another server that already uses Maildir.) I'd like Dovecot to find Maildir in $HOME of my virtual users as their inbox. So I tried to use the following in my users.passwd file: test:{PLAIN}some_password:30003:30003::/home/vmail/domain/test:/bin/false::maildir:%h/Maildir/:INBOX=maildir:%h/Maildir/ Unfortunatelly this doesn't work and dies with this message: Mar 8 16:44:25 logout dovecot: imap(test): Ambiguous mail location setting, don't know what to do with it: /home/vmail/isc.cvut.cz/test/mbox (try prefixing it with mbox: or maildir:) Mar 8 16:44:25 logout dovecot: imap(test): Failed to create storage for '' with data: /home/vmail/isc.cvut.cz/test/mbox Mar 8 16:44:25 logout dovecot: child 41976 (imap) returned error 89 Is it even possible to override the setting from dovecot.conf like this?

[Dovecot] C programmers, please help. need dovecot patch
by Adam M. Dunn 05 Apr '06

05 Apr '06

Hi all. Can any C programmers out there tell me how to fix Dovecot to default to Maildir format when autodecting can't find anything? I don't know C, but it seems like it would be a simple thing. Right now, I use the autodetect mailbox feature because we want users to choose to optionally be able to use Mbox format (we have some diehard unix users with non-maildir clients). I have Maildrop setup to check for the existance of a ~/Maildir folder in the user's home, and if it exists, it delivers there. Otherwise it falls back to ~/Mail where mbox style files go. The problem with Dovecot is there is no way to tell the autodetect feature what to default to, and if it can't find anything, it automatically creates a folder called ~/mail under the user's home and primes it with an Mbox file, but I'd rather it create a ~/Maildir instead. So if we have for example, a new user with no mail yet, and they log in via IMAP before getting any mail from maildrop, Dovecot will create a them a ~/mail folder. So when they DO get mail, our maildrop filters will think they are an Mbox user. I could do some fancy Maildrop filters to fix that when they get their first mail, but in the meantime the unknowing user could try creating things via IMAP that gets overwritten. Anyway, it would be much cleaner if Dovecot just did what I wanted. If anyone could point me to the place to patch my copy of Dovecot, I would GREATLY apprecieate it. I don't know C, but I know many other languages. I would also like to see this be added via the config file in future releases. So consider this a feature request. Not only that, but more control over the autodetection process in general would be REALLY nice. Thanks. Adam

[Dovecot] Setting a Default Domain
by Richard Laager 05 Apr '06

05 Apr '06

I'm working on migrating to Dovecot. At the moment, I have a mail path that includes the domain, so I'm using %d to get that. However, if users authenticate without specifying a domain (i.e. using "bob" instead of "bob(a)wiktel.com"), then %d expands to nothing. I'd like to have that expand to a default domain (wiktel.com) instead. Is that possible? Thanks, Richard
