[Dovecot] Multiple userdb possible?
by Nikolaos Milas 07 Feb '12

07 Feb '12

Hello, I am running v2.0.13. In my dovecot.conf I have: userdb { args = /etc/dovecot/dovecot-usrdb-ldap.conf driver = ldap } passdb { args = /etc/dovecot/dovecot-passdb-ldap.conf driver = ldap } Is it legitimate to include multiple ldap userdb's, like: userdb { args = /etc/dovecot/dovecot-usrdb-ldap1.conf driver = ldap } passdb { args = /etc/dovecot/dovecot-passdb-ldap1.conf driver = ldap } userdb { args = /etc/dovecot/dovecot-usrdb-ldap2.conf driver = ldap } passdb { args = /etc/dovecot/dovecot-passdb-ldap2.conf driver = ldap } If it is legitimate (in case configuration is different, please correct me), in which sequence userdb's are evaluated? Thanks, Nick

[Dovecot] Configuration problem?
by Anne Wilson 07 Feb '12

07 Feb '12

I have a new Scientific Linux 6.1 mail server (dovecot -n below) and am seeing the following in the logs, with no idea what is happening: --------------------- Dovecot Begin ------------------------ Dovecot was killed, and not restarted afterwards. **Unmatched Entries** dovecot: imap(anne): Connection closed bytes=205614/894243: 1 Time(s) dovecot: imap(anne): Disconnected: Logged out bytes=24296/89310: 1 Time(s) dovecot: imap(anne): Disconnected: Logged out bytes=24526/76772: 1 Time(s) dovecot: imap(anne): Disconnected: Logged out bytes=26254/75778: 1 Time(s) dovecot: imap(anne): Disconnected: Logged out bytes=27948/134120: 1 Time(s) dovecot: imap(anne): Disconnected: Logged out bytes=29304/116087: 1 Time(s) dovecot: imap(anne): Disconnected: Logged out bytes=34802/914087: 1 Time(s) dovecot: imap(anne): Disconnected: Logged out bytes=4457/11719: 1 Time(s) dovecot: imap(anne): Disconnected: Logged out bytes=5322/184434: 1 Time(s) dovecot: imap(anne): Disconnected: Logged out bytes=61388/106618: 1 Time(s) dovecot: imap(anne): Disconnected: Logged out bytes=6164/21347: 1 Time(s) dovecot: imap(anne): Disconnected: Logged out bytes=7914/89868: 1 Time(s) dovecot: imap: Server shutting down. bytes=1309821/4473013: 1 Time(s) dovecot: imap: Server shutting down. bytes=14215/97371: 1 Time(s) dovecot: imap: Server shutting down. bytes=1459/9382: 1 Time(s) dovecot: imap: Server shutting down. bytes=1688/26161: 1 Time(s) dovecot: imap: Server shutting down. bytes=1705/5038: 1 Time(s) dovecot: imap: Server shutting down. bytes=3146/79269: 1 Time(s) dovecot: master: Dovecot v2.0.9 starting up (core dumps disabled): 1 Time(s) ---------------------- Dovecot End ------------------------- dovecot -n # 2.0.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-131.0.15.el6.x86_64 x86_64 Scientific Linux release 6.1 (Carbon) mail_location = maildir:~/Maildir/ mbox_write_locks = fcntl passdb { driver = pam } protocols = imap ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem userdb { driver = passwd } /etc/dovecot/dovecot.conf: - everything being defaults, as far as I can see, apart from these lines: # Protocols we want to be serving. protocols = imap listen = *, :: mail_location = maildir:~/Maildir/ maildir_copy_with_hardlinks = yes Is it really expecting an mbox file? I'm completely bogged down with this - my previous setup was fine, but the old config file doesn't work with this system. Any help and/or pointers would be greatly appreciated. Anne

[Dovecot] dsync error Mailbox has children, delete them first
by Jürgen Obermann 07 Feb '12

07 Feb '12

Hi, I use dsync to backup mailboxes from mbox format to mdbox on a remote system. The first run for a user with dsync is OK, but during the second there are lots of the following errors: dsync-remote(user): Error: Can't delete mailbox directory Example: Mailbox has children, delete them first I see no way how I could influence the order dsync deletes mailboxes. This happens with dovecot version 2.0.16 Thank you, Juergen Obermann

[Dovecot] ENVELOPE mishandling of Subject lines with quote(s)?
by Dinh Le 07 Feb '12

07 Feb '12

Hi, I am running dovecot version 1.2.9 on a Ubuntu 10.04 server. To obtain the message's header info from this dovecot imap server, I run the following imap command on a client side's imap session: . fetch 88:90 (envelope) which returns (in this case) ------------------------------------------------------------- * 88 FETCH (ENVELOPE ("Tue, 28 Oct 2008 15:45:35 -0500" "Linear Actuators Bring Flexibility to Packaging" (("Design World" NIL "subscription" "designworldonline.com")) (("Design World" NIL "subscription" "designworldonline.com")) (("Design World" NIL "subscription" "designworldonline.com")) ((NIL NIL "dinh" "flic.net")) NIL NIL NIL "<490779CF.00000E7D(a)ak119.mta.exacttarget.com>")) * 89 FETCH (ENVELOPE ("29 Oct 2008 15:44:03 -0500" {65} 2nd Edition of Brennesholtz/Stupp "Projection Displays" Available (("Insight Media" NIL "administrator" "insightmedia.info")) (("Insight Media" NIL "administrator" "insightmedia.info")) (("Insight Media" NIL "administrator" "insightmedia.info")) ((NIL NIL "dinh" "flic.net")) NIL NIL NIL "<20081029154358.0C359AE169595F1B(a)insightmedia.info>")) * 90 FETCH (ENVELOPE ("Thu, 30 Oct 2008 04:24:31 +0800 (SGT)" "6 new products Now Online!" (("Global Sources Product Alert" NIL "paservices" "globalsources.com")) (("Global Sources Product Alert" NIL "paservices" "globalsources.com")) (("Global Sources Product Alert" NIL "paservices" "globalsources.com")) (("Dinh Le" NIL "dinh" "flic.net")) NIL NIL NIL "<352725277.1225311871753.JavaMail.web(a)fuchsia3.globalsources.com>")) . OK Fetch completed. -------------------------------------------------------------- Notice that message 89's Subject line Subject: 2nd Edition of Brennesholtz/Stupp "Projection Displays" Available has quotes and this dovecot's ENVELOPE response failed to get parsed by a popular Perl module (Mail::IMAPClient::BodyStructure::Envelope). I have a hunch that this is dovecot's fault but I could be wrong. How should dovecot (or any imap server) deal with Subject lines with quotes inside ENVELOPE? ENVELOPE seems to encapsulate most of the important information and its format can be parsed cleanly and quickly. I prefer to fetch ENVELOP, at this point, rather than the other alternatives. Thanks for your help, Dinh

[Dovecot] Question about quota configuration
by przemek.orzechowski＠makolab.pl 06 Feb '12

06 Feb '12

Hi This is my first post here so i will be as precise as i can I'm trying to setup a quota system using dovecot postfix and procmail dovecot version 1.2.9 postfix version 2.7.0 I have succesfully modified dovecot config to use fs quota system (so far imap and pop3) It reports correct quotas to imap and pop3 clients (both user and group) What im tryin to do now is to modify postfix->procmail->dovecot config in a way that if user is over quota mail delivery is delayed instead of bouncing. (is this possible?) Second thing i would like to achive is that when authenticated users close to quota/group quota for example 10MB to quota limit try sending email theyr mail is rejected and preferably an email is generated telling them to free some space for new mails first. (is such a thing possible?) MS Exchange servers have such a feature and I would like to get such a functionality on my linux mailserver I'm trying to prevent a situation when mails are lost due to quota problems. This setup was initially a typical virtualmin installation with a system on single partition. Thanks in advance for all Your suggestions

[Dovecot] doveadm purge on shared storage
by Jan-Frode Myklebust 06 Feb '12

06 Feb '12

We've finally (!) started to put some users on mdbox instead of maildir, and now I'm wondering about the purge step. As we're running GPFS for the mailboxes (and dovecot director in front of every dovecot service), is it important to run the "doveadm purge -u $user" on the same host as $user is logged into to avoid index corruption ? If so, will we need to run the "doveadm purge" trough the dovecot director as well? -jf

[Dovecot] Sieve notify messages
by Andreas Muehlemann 05 Feb '12

05 Feb '12

Hi All I'm using dovecot 2.0.16 with the pigeonhole plugin 0.25. I'm trying to use the notifiy mechanism from sieve to send notifications when a mail arrives in the mailbox. The message is checked to be a 8bit message, otherwise it is replaced by the default message "Notification of new message." How can I create a 8bit message body within the sieve script that is accepted by the notification process? e.g. notify :message "Subject: ${subject}" "mailto:email@domain.com"; Do I have to put the message body into the :message string? Or how can I define a custom message body that is accepted by notify? Best regards Andreas
