[Dovecot] Delivery notifications
by Brandon Keepers 24 Jul '08

24 Jul '08

I'm working on an application that is backed by Postfix 2.3.8 and Dovecot 1.0.13, configured with virtual domains, for handling messaging. I need to be able to send the notification (such as "You've received a new message on SomeAwesomeService. Click here to check it out", It's evil, I know) to a different email address, such as a mobile device. Eventually, we want to do other things like clear web page caches when a message is received, or sending IM notifications, but that's for another day. So basically, we want to notify our application whenever a new mail is received, and it can do all the magical things that it needs to do. I was hoping to get some feedback on the different approaches I'm looking at. From what I can tell, there's not a way to deliver to multiple virtual transports in postfix, so here's the options I see: * Content filter I could set up a "content filter" that just delivers the mail to the application, and then re-injects it back into postfix. This seems like more work than the other options just because I have to worry about re- injecting the message * Intercept delivery Replace the dovecot deliver command with a custom one that calls the dovecot deliver and then passes the message on to the application. I've written a little proof of concept for this and it seems to work, but just seem shady. * Sieve Dovecot supports Sieve, so I could just have a global sieve script that sends the notifications. This is definitely the solution I'm leaning towards. Are there any better options? Do you think this will have a significant impact on performance? Am I crazy? Thanks, Brandon

[Dovecot] making IMAP quicker on LAN
by Andrew Von Cid 24 Jul '08

24 Jul '08

Hi all, I keep on hitting this problem when migrating new clients from POP or local IMAP servers (hosted on their LAN's) to my Dovecot setup, which is hosted properly in a data center. People usually complain that it's slower and although they're getting a kick ass mail setup it doesn't look good from their point of view. I'm wondering if there is anything I could do to speed it up on their LAN's. What I mean is probably a caching IMAP proxy or some sort of replication to a local Dovecot server. Is this something Dovecot can do? I'd be really grateful for any opinions on how to tackle this problem. Many thanks, Andrew.

[Dovecot] how to store flags \Seen into read-only mailbox?
by seriv＠parkheights.dyndns.org 24 Jul '08

24 Jul '08

Hi, I'm trying to use dovecot for storing mailing lists and read-only access for users. The OS is Solaris, authentication for all readers of these lists are from Ldap through PAM, and one local user "listuser" will receive all mail and store them into it's folders (Maildirs). These maildirs are readable (read-only) for all others and they are shared by setting --- mail_location: maildir:/home/vmail/listuser/Maildir:CONTROL=/home/vmail/%u/Maildir/control:INDEX=/home/vmail/%u/Maildir/index --- Mail became readable because in each mail folder to be shared there is dovecot-shared with mode 064, and all users included into his group. But this is the problem: how to have flag \Seen stored in read-only mailbox? As recorded by rawlog, it is ignored now: --- bash-3.00# cat 20080724-103219-10616.in 3 namespace 4 lsub "" "*" 5 list "" "INBOX" 6 list "" "Trash" 7 create "Trash" 8 select "OmniTI.FreeLotto.Ops" 9 UID fetch 1:* (FLAGS) 10 uid store 1:3 +Flags (\Seen) 11 IDLE DONE 12 close 13 logout bash-3.00# cat 20080724-103219-10616.out * OK [RAWLOG TIMESTAMP] 2008-07-24 10:32:19 * NAMESPACE (("" "."))

Hmm. I don't necessarily see that as a desirable feature because in the case that something is actually wrong with the spam tagging you want to notice it isn't working right. If you really need that, just don't set an error when it happens and do nothing, allowing the move. johannes

Hi, I recently installed an IMAP server with dovecot and the dovecot antispam plugin with dspam backend. If I configure dspam to not include the signature in the X-DSPAM-Signature header will I be able to move mail into SPAM folder? Regards, Isabel

[Dovecot] Conversion help
by Jason Frisvold 24 Jul '08

24 Jul '08

Hi there, I'm working on converting my server from using bincimap to dovecot. I seem to be having some trouble with folders, however. Binc was set up like this : depot = "IMAPdir", /* Use Maildir++ style type = "Maildir", /* only Maildir path = "Maildir", /* default path */ auto create inbox = "yes", /* create INBOX in auto subscribe mailboxes = "INBOX", /* list mailboxes umask = "077" /* use this umask I have dovecot set up thusly : mail_location = maildir:/home/vpopmail/domains/%d/%n/Maildir namespace private { separator = / prefix = INBOX/ inbox = yes hidden = yes } The problem is, I'm not seeing any folders.. If I do a listing in the directory, I see this : -rw------- 1 vpopmail vchkpw 35453 Mar 10 2004 bincimap-cache -rw------- 1 vpopmail vchkpw 702 Jul 16 19:20 .bincimap-subscribed -rw------- 1 vpopmail vchkpw 73 Mar 10 2004 bincimap-uidvalidity drwx------ 2 vpopmail vchkpw 532480 Jul 21 11:49 cur -rw------- 1 vpopmail vchkpw 25956 Jul 21 11:49 dovecot.index -rw------- 1 vpopmail vchkpw 35840 Jul 21 11:49 dovecot.index.cache -rw------- 1 vpopmail vchkpw 18220 Jul 21 11:49 dovecot.index.log -rw------- 1 vpopmail vchkpw 42080 Jul 21 11:34 dovecot.index.log.2 -rw------- 1 vpopmail vchkpw 106631 Jul 21 11:49 dovecot-uidlist drwx------ 2 vpopmail vchkpw 4096 Jul 21 09:38 INBOX drwx------ 5 vpopmail vchkpw 4096 Jul 20 16:17 INBOX\.Drafts drwx------ 5 vpopmail vchkpw 4096 Jul 16 18:53 INBOX\.Learn FP drwx------ 5 vpopmail vchkpw 4096 Jul 20 17:37 INBOX\.Learn Spam drwx------ 5 vpopmail vchkpw 4096 Jul 16 18:56 INBOX\.Sent drwx------ 5 vpopmail vchkpw 4096 Jul 20 17:37 INBOX\.Spam drwx------ 5 vpopmail vchkpw 4096 Jul 21 11:44 INBOX\.Trash drwx------ 2 vpopmail vchkpw 348160 Jul 21 11:53 new -rw------- 1 vpopmail vchkpw 0 Jul 21 11:34 subscriptions drwx------ 2 vpopmail vchkpw 4096 Jul 21 11:53 tmp -rw------- 1 vpopmail vchkpw 72 Jul 16 18:57 uidvalfilename It would appear that I need to use . as my separator, but that doesn't work either..

[Dovecot] v1.1.2 release candidate
by Timo Sirainen 24 Jul '08

24 Jul '08

I've finally read and answered most of the mails on this list. If you haven't received an answer to your question, resend it. There are a couple of tricky mbox issues left, but I'm not sure if I can do anything about them unless someone can show me how to reproduce the problems. There are quite a lot of new features in v1.1.2 actually. Most of them are in plugins so hopefully they shouldn't destabilize anything. Anyway I tought I'd just in case put out a quick release candidate so at least a few people could try it. I'll probably make the final v1.1.2 release in a day or two. So, please test: http://dovecot.org/tmp/dovecot-1.1.2-rc.tar.gz Largest changes since v1.1.1 are: + Added full text search indexing support for Apache Lucene Solr server: http://wiki.dovecot.org/Plugins/FTS/Solr + IMAP SORT: Added X-SCORE sort key for use with Solr searches. + zlib plugin supports now bzip2 also. + quota: All backends now take noenforcing parameter. + Maildir: Add ,S=<size> to maildir filename whenever quota plugin is loaded, even when not using Maildir++ quota. + deliver: Allow lda section to override plugin settings. + deliver: Giving a -m <namespace prefix> parameter now silently saves the mail to INBOX. This is useful for e.g. -m INBOX/${extension} + Added a new maildirlock utility for write-locking Dovecot Maildir. + dict-sql: Support non-MySQL databases by assuming they implement the "INSERT .. ON DUPLICATE KEY" using an INSERT trigger. - SORT: Fixed several crashes/errors with sort indexing. - IMAP: BODYSTRUCTURE is finally RFC 3501 compliant. Earlier versions didn't include Content-Location support. - IMAP: Fixed bugs with listing INBOX. - Maildir: maildirfolder file wasn't created when dovecot-shared file existed on the root directory - deliver didn't expand %variables in namespace location settings. - zlib: Copying non-compressed messages resulted in empty mails (except when hardlink-copying between maildirs). - mbox-snarf plugin was somewhat broken - deliver + Maildir: If uidlist couldn't be locked while saving, we might have assert-crashed

[Dovecot] Problems with deliver and account resolving
by Andreas Podgurski 24 Jul '08

24 Jul '08

Hi! I'm currently setting up my first mailsystem based on dovecot. For a far way, working with dovecot was very convenient, but after I had to integrate deliver, it became massivly painful. My components are postfix as MTA, postgresql as user database and dovecot as IMAP server. When translating the mail adresse into the account name, something goes terribly wrong (Mail adresses modified to protect against spam, think about them in correct format): dovecot: Jul 22 01:48:13 Info: auth(default-listen): master in: USER 1 Andreas.Podgurski_at_MediaGUILD.de service=deliver dovecot: Jul 22 01:48:13 Info: auth(default-listen): prefetch(Andreas.Podgurski_at_MediaGUILD.de): passdb didn't return userdb entries, trying the next userdb dovecot: Jul 22 01:48:13 Info: auth(default-listen): sql(Andreas.Podgurski_at_MediaGUILD.de): SELECT 1011 AS uid,1011 AS gid,'/var/www/jade/mail/' || admin.username AS home,admin.username AS user FROM admin,email WHERE lower(email.local_address) = lower('Andreas.Podgurski') AND email.receiver = admin.id; dovecot: Jul 22 01:48:13 Info: auth(default-listen): auth(Andreas.Podgurski_at_MediaGUILD.de): username changed Andreas.Podgurski_at_MediaGUILD.de -> SunAdmin dovecot: Jul 22 01:48:13 Info: auth(default-listen): master out: USER 1 SunAdmin uid=1011 gid=1011 home=/var/www/jade/mail/SunAdmin deliver(Andreas.Podgurski_at_MediaGUILD.de): Jul 22 01:48:13 Error: mkdir(/var/www/jade/mail/Andreas.Podgurski_at_MediaGUILD.de/cur) failed: Permission denied deliver(Andreas.Podgurski_at_MediaGUILD.de): Jul 22 01:48:13 Info: msgid=<20080721234813.302260(a)gmx.net>: save failed to INBOX: Internal error occurred. Refer to server log for more information. [2008-07-22 01:48:13] As you can see, the account SunAdmin has an email adresse andreas.podgurski_at_mediaguild.de assigned. The database seems to reveil the username correctly, but after that, deliver continues to use the original mail adresse, not the account name returned by the auth master. Any idea, where my solution went the wrong way? The uid/gid belong to vmail:vmail, which is used for the auth-master, as well as for running deliver and to dispatch the postfix messages. Btw., I ask myself, how dovecot can assume to use prefetch in this case, as prefetch bases upon the password query, which has to fail in this case, as there is no password. Shouldn't it not even try to use the prefetch values there...? Thanks in advance, Andreas Podgurski -- Psssst! Schon vom neuen GMX MultiMessenger gehört?
