Emails arrive with 2 Return-Paths when using lmtp director. Is this something configurable in the director or is this a bug?

[Dovecot] old messages being delivered to blackberry
by Luc Belliveau 19 Apr '12

19 Apr '12

Several users are reporting old messages (sometime years old) are being delivered as new on their blackberry devices... I've confirmed that this happens to all blackberry users... I believe the problem is related to this error: Maildir: Expunged message reappeared, giving a new UID In fact, this is the only mail related error message on the server... the mail is stored on a glusterfs share, and I'm using director to prevent simultaneous access... although I wasn't able to get LMTP to work with Director... to simplify things, I've temporarily only enabled 1 dovecot server anyway, to get everything else working first... I'll fiddle with lmtp later... so right now only 1 server is accessing the mailboxes. Delivery is also done from that one server, from postfix. Possibly caused by GlusterFS, the indexes were still getting corrupted, even with only 1 server... so I've moved the indexes to a local directory on each server. I'm no longer getting index related errors... but the expunged error is still occuring... and the error seems to happen a few moments before the BB gets a bunch of messages... so it's very likely related. I would like to continue using GlusterFS if possible; I haven't found any indication that it is outright unsupported, as long as I'm using Director... I am using dovecot 2.0.16. Any help would be appreciated! Here is my configuration: # 2.0.16: /etc/dovecot/dovecot.conf # OS: Linux 3.1.9-1.4-desktop i686 openSUSE 12.1 (i586) auth_mechanisms = plain login disable_plaintext_auth = no log_timestamp = "%Y-%m-%d %H:%M:%S " mail_fsync = always mail_location = maildir:~/Maildir:INDEX=/var/indexes/%u mail_nfs_storage = yes mail_privileged_group = vmail managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave passdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } plugin { quota = dict:user::file:/var/vmail/%d/%n/.quotausage sieve = /var/vmail/%d/%n/.sieve } postmaster_address = postmaster(a)bigdata.nb.ca service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-userdb { group = vmail mode = 0666 user = vmail } user = root } service lmtp { inet_listener lmtp { port = 24 } unix_listener /var/spool/postfix/private/dovecot-lmtp { mode = 0660 user = postfix } } ssl_ca = </etc/postfix/smtpd.bundle ssl_cert = </etc/postfix/smtpd.cert ssl_key = </etc/postfix/smtpd.key userdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } protocol imap { imap_client_workarounds = delay-newmail mail_plugins = quota imap_quota } protocol pop3 { mail_plugins = quota pop3_uidl_format = %08Xu%08Xv } protocol lda { mail_plugins = sieve quota } protocol lmtp { mail_plugins = quota sieve } Luc

[Dovecot] Re-indexing of fts-solr not working
by Joe Beaubien 18 Apr '12

18 Apr '12

Hi, I am currently testing a 2.1 dovecot setup with fts-solr. Search speed is simply amazing. I decided to try to delete and rebuild the solr indexes, but i can't seem to rebuild them thru dovecot. At first, when telnetting to the imap server, the search initially built the index, and then subsequent searches are blazingly fast. 1- I deleted all the solr indexes with the following query: <delete><query>*:*</query></delete> 2- Flag the mailbox to be re-indexed: doveadm force-resync INBOX At this point, it doesn't work. When I telnet into the imap server, the searches always come back empty 3- I also tried a few other commands: doveadm fts rescan, doveadm index INBOX. Still no search results. Nothing seems to be appearing in the logs when I issue all the doveadm commands. What did I miss? Thanks, Joe

[Dovecot] namespace hierarchy
by Tom Fernandes 18 Apr '12

18 Apr '12

Hi, I'm migrating from Courier to Dovecot and would like to keep the original namespace and add two new ones on the new server. There's only one namespace in Courier which is "INBOX." . The seperator is "." In the new server I would like to have 3 namespaces (private, public, shared) and use "/" as separator. Is it possible to keep "INBOX." for private, so that the users mailboxes appear below the Inbox, but have public and shared on the same hierarchy-level like the Inbox? When I set prefix to "INBOX/" for private I get the users mailboxes below the Inbox, like I have it Courier now. But then at least the public, probably also the shared namespace doesn't work any more. I get "unknown subscription namespace" when trying to subscribe to some of the folders. My current configuration is: namespace: type: private separator: / inbox: yes list: yes subscriptions: yes namespace: type: public separator: / prefix: public/ location: maildir:/var/vmail/example.com/public list: yes namespace: type: shared separator: / prefix: shared/%%u/ location: maildir:%%h/Maildir list: yes warm regards, Tom

[Dovecot] LMTP auth problem
by Cor Bosman 18 Apr '12

18 Apr '12

hey all, im getting the following error: Apr 14 14:29:44 lmtpdirector1 dovecot: auth: Error: passdb(scorpio,127.0.0.1): Auth client doesn't have permissions to do a PASS lookup: /var/run/dovecot/auth-userdb mode=0666, but not owned by UID 112(dovecot) Apr 14 14:29:44 lmtpdirector1 dovecot: lmtp(18298): Error: user scorpio: Auth PASS lookup failed My config. Director servers running both imap and lmtp with a matching set of real servers accepting imap/lmtp. Imap is working fine, and has been working fine for a while. Im trying to add lmtp to the director, but i cant seem to get that working. We're passing passdb on to the real servers. How does this work with lmtp? protocols = imap lmtp protocol lmtp { auth_socket_path = director-userdb } lmtp_proxy = yes # passdb check on real servers passdb { driver = static args = proxy=y nopassword=y } Cor

[Dovecot] Hints for a NFS-Setup
by Patrick Westenberg 18 Apr '12

18 Apr '12

Hi everyone, as I have often trouble with OCFS2 I want to switch to NFS but I'm not sure how to rebuild my cluster with regard to locking and indexing problems. By now my I have a four server configuration (there are another 2 servers for outgoing mail but they can be ignored): MTA(MX10) --(lmtp/socket)--> local dovecot --> iSCSI-LUN with OCFS2 MTA(MX10) --(lmtp/socket)--> local dovecot --> iSCSI-LUN with OCFS2 IMAP-User <--(imap)--> IMAP-Server1 (local dovecot) <--> iSCSI-LUN/OCFS2 IMAP-User <--(imap)--> IMAP-Server2 (local dovecot) <--> iSCSI-LUN/OCFS2 As far as I understood I will get poor performance if I'd just switch from OCFS2 to NFS (while keeping this configuration) with 4 hosts accessing the NFS-share and the index files on it and it is recommended to assign users to a specific host (http://wiki2.dovecot.org/NFS) I'm uncertain what's the meaning of "user" in this context. Is it an IMAP-User or every incoming mail? An IMAP-User assigned to a specific IMAP-Server is ok for me and I could store and profit from local index files. However, I want my incoming mailservers to be equally receiving mails. Both should accept mails for every mailbox but in this case I won't have local indexes. I would appreciate any hints. Patrick

[Dovecot] 487 imap-login processes - is this ok
by Götz Reinicke 18 Apr '12

18 Apr '12

Hi, recently I checked our mailserver for some more tuning and optimizing and noticed, that currently I do have 487 imap-login processes and I'm asking myself if that's o.k. We do have about 1.000 user in total and not everybody is currently logged in. May be this is o.k. but if not, what might I check? We run the dovecot package provided by redhat EL 5.8 dovecot-1.0.7-7.el5_7.1 Thanks for any comment or suggestion. Regards .

[Dovecot] returning a namespace location from userdb?
by Cor Bosman 18 Apr '12

18 Apr '12

hey all, is it possible to return the location of namespace from the userdb lookup? The code is a bit unclear about it. There seems to be a part of the docs saying: If you want to override settings inside sections, you can separate the section name and key with '/'. For example: namespace default { inbox = yes } The inbox setting can be overridden by returning namespace/default/inbox=no extra field I realize you can set 'location=' in the namespace, but we have mailbox locations that cant be expressed by the normal variable substitution vars in dovecot (dont ask). So we have a userdb that returns the correct mail location. This works fine. But im currently trying to implement a second namespace, and Im having trouble returning a mailbox location for this specific namespace from our userdb. Is this possible? If so, what would the userdb have to return exactly? namespace spam { type = private separator = / inbox = no prefix = Spam/ subscriptions = no list = yes hidden = yes } Regards, Cor
