[Dovecot] Restricting IMAP access
by Thierry de Montaudry 04 Nov '11

04 Nov '11

Hi list, I have a setup with postfix+dovecot+mysql unser CentOS 5, running 50 odd domains with virtual users. Access is allowed for public POP3, and a webmail on apache+PHP solution through local IMAP. I'm not gonna give you the long story about the why, but I'm looking for a way to give public IMAP access only to one domain, knowing that users log in with full email (user(a)domain.tld) Anybody has a trick for that? Running dovecot 2.0.13. I know there should be a way to do it through the database, but quite heavy change on our side for a million odd users. Regards, Thierry

[Dovecot] Dot Lock timestmap, users disconnections from roundcube
by Maria Arrea 04 Nov '11

04 Nov '11

Hello. We are running dovecot 2.0.13 with mdbox+zlib on RHEL 5.7 x64, ext4. We use NTP. Indexes are in a iSCSI raid 10, mailboxes in raid5. No NFS. We have detected that sometimes all users get disconnected from roundcube at the same time. In dovecot logs we hundreds of lines like this: Nov 3 09:23:07 buzon dovecot: imap(mcrivero@mydomain): Warning: Created dotlock file's timestamp is different than current time (1320308587 vs 1320308542): /buzones/mydomain/03/67/mcrivero/subscriptions Nov 3 09:23:07 buzon dovecot: imap(mcrivero@mydomain): Connection closed bytes=0/295 Nov 3 09:23:07 buzon dovecot: imap(delolmo@mydomain): Warning: Created dotlock file's timestamp is different than current time (1320308587 vs 1320308542): /buzones/mydomain/15/77/delolmo/subscriptions Nov 3 09:23:07 buzon dovecot: imap(delolmo@mydomain): Connection closed bytes=0/295 I have been googling but I only see problems with remote NFS, our setup does not use NFS.

[Dovecot] IMP, Dovecot and multiple namespaces
by Rick Romero 04 Nov '11

04 Nov '11

Hey guys, I'm wondering what the best way is to be backwards compatible with Courier mailbox formats and not duplicate mailbox trees with Dovecot. Is anyone doing this right now? My Dovecot 2.0.13 is configured as follows for Namespaces: namespace { inbox = yes location = prefix = separator = . } namespace { hidden = yes inbox = no list = no location = prefix = INBOX. separator = . } So I should have an INBOX, plus additional root folders - rather than the Courier default of all folders being subfolders of the INBOX. So when I run LIST in IMAP I get - 08 LIST "" % * LIST (\HasChildren) "." "INBOX" * LIST (\HasChildren) "." "Spam" * LIST (\HasNoChildren) "." "Sent" * LIST (\HasNoChildren) "." "Trash" * LIST (\HasNoChildren) "." "Junk" * LIST (\HasNoChildren) "." "Drafts" Which looks fine. The problem is, IMP (old and new) show two sets of mailboxes (one for each namespace) like so: INBOX Spam Spam.Over10 Sent INBOX.Spam INBOX.Spam.Over10 INBOX.Sent (etc) I assume IMP is walking the INBOX because it says it has Children, and displaying those Children - The Horde team is telling me that's the root of the problem. It makes sense, but I'm not sure what the real solution is. Is it possible to disable Children for a mailbox when an alternate hidden namespace matches the mailbox name? Does that make sense? Or, is there another option I change change in the dovecot config to accomplish the same? Rick

[Dovecot] Different default realm per listener
by Kai Arif 04 Nov '11

04 Nov '11

Hi all! I want create a large IMAP server setup where dovecot is listening on multiple interfaces and needs a different default realm on each interface. I'm using dovecot 2.0.5 on FreeBSD9 and authenticate against a LDAP database. I found an old mail thread from 2007 that said I'm basically screwed. Has that change since than? Is there any way to use different default realms per listener?

[Dovecot] LDAP w/SASL "Active Directory" authentication failing.
by David Varela 04 Nov '11

04 Nov '11

Hello, I am running a Dovecot server (version 1.2.17) on FreeBSD 8.2, using LDAP to authenticate Active Directory users. I can successfully bind and authenticate using PLAIN and LDAP without SASL, but obviously passwords for the bind user and the user being authenticated are being passed in plain text. I've attempted to configure my server to us SASL however when I attempt to authenticate a user I see authentication failures. I reviewed the security log on my domain controller and see that the bind user is binding properly, so the issue appears to be orginating from the user authentication, however I cannot determine what the issue is. Here is all the information regarding my configuration, along with the logs from the server: Dovecot -n # 1.2.17: /usr/local/etc/dovecot.conf # OS: FreeBSD 8.2-RELEASE i386 ufs log_path:

by Osvaldo Alvarez Pozo 04 Nov '11

04 Nov '11

Hello all, I am testing postlogin script with dovecot 2. I works but i would like that the imap and pop session get executed even if the post-login script fail. my postlogin script is very simple: #/etc/dovecot/conf.d/10-master.conf service imap { executable = imap imap-postlogin } # service imap-postlogin { executable = script-login /usr/local/bin/postlogin.sh unix_listener imap-postlogin { } } service pop3 { executable = pop3 imap-postlogin } #/usr/local/bin/postlogin.sh echo "UPDATE mailbox SET last_login = now() WHERE username = '$USER'" | mysql -upostlogin -pXXXXXXXX postfixadmin exec "$@" Thanks in advance Osvaldo

[Dovecot] What owner/permissions for virtual homes?
by sean darcy 04 Nov '11

04 Nov '11

VirtualUsers.Home.txt: The directory layouts for home and mail directories could look like one of these (in the preferred order): 1. Mail directory under home, for example: home='/var/vmail/domain/user/' mail='/var/vmail/domain/user/mail/' Who should be the owner of these directories, with that permissions? Does it make a difference if it's /home/vmail rather than /var/vmail? Thanks, Jay

[Dovecot] doveadm 'proxy list' or 'who' not working ?
by de Lafond Guillaume 04 Nov '11

04 Nov '11

Hi, I switched from dovecot 1.2.* to 2.0.* for a mail proxy. I try to play with the new cool utility doveadm, but I don't manage to get results from it. # /usr/local/dovecot-2.0.15/bin/doveadm proxy list username proto src ip dest ip port # As 'proxy list' does not return anything, I tried with 'who' # /usr/local/dovecot-2.0.15/bin/doveadm who -a /var/run/dovecot-socket-auth/anvil username # proto (pids) (ips) # I think it should display something as I have many user connected : #ps axww | grep imap ... 21194 ? S 0:11 dovecot/imap-login [13 connections (8 TLS)] 21195 ? S 3:38 dovecot/imap-login [47 connections (38 TLS)] 29463 ? S 1:00 dovecot/imap-login [210 connections (183 TLS)] ... I should have something that is not well configured.. but I don't manage to find it. Does anybody have an idea where I should look to solve this ? Here is my dovecot.conf : # /usr/local/dovecot-2.0.15/bin/doveadm config # 2.0.15: /usr/local/dovecot-2.0.15/etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-amd64 x86_64 Debian 6.0.2

[Dovecot] POP server migration and duplicate messages.
by Ernie Dunbar 04 Nov '11

04 Nov '11

I'm having trouble with Dovecot where my mail client (if it matters, I'm using Evolution) collects some duplicate messages when switching between POP servers that have the same messages on them. I'm doing this as a test for server migration for all of our clients. Here's my procedure: 1. set up Dovecot and Exim on the new server so that everything works like on the old server. The old server also uses Dovecot and Exim, so very few things changed. 2. On the new server, use NFS to access the users' Maildirs on a remote NFS server. 3. Sync the Maildirs on the NFS store from the old server with SCP (and I do a quick SCP sync on my own Maildir during testing to ensure that this process is quick). 4. Check mail in Evolution on the old server. 5. Change Evolution's server settings to use the new server. 6. Check mail again. Evolution is set to keep messages on the server for one week, and about 20 of the 184 messages on the server keep getting re-downloaded. From a random sampling, the UIDL of the messages checks out between both servers, so I really don't understand what's going on here. If this is just a bug in Evolution, then that means I can just go ahead with the full migration and hope that people aren't going to be stuck with re-downloading their entire mailbox which in some cases, means hundreds or thousands of messages.

[Dovecot] GSSAPI and deny=yes passdb
by Sergey Urushkin 04 Nov '11

04 Nov '11

Hi. Is it possible to use GSSAPI authentication and deny passdb together? Seems it doesn't work as I expect: GSSAPI doesn't check deny passdb, so I'm not able to restrict access to GSSAPI-users. I can see these in logs when user tries to connect with PLAIN authentication (via pam_krb5): Oct 4 11:14:31 vm03 auth: Debug: passwd-file(testuser,172.17.0.123): lookup: user=testuser file=/etc/dovecot/auth.d/.passwd-deny Oct 4 11:14:31 vm03 dovecot: auth: passdb(tesetuser,172.17.0.123): User found from deny passdb But that's what I see if user logs in with GSSAPI: ...

Thanks. -- Best regards, Sergey Urushkin
