[Dovecot] SELECT/EXAMINE don't report URLMECH
by Mike Abbott 06 May '13

06 May '13

In dovecot-2.2.1 neither the SELECT nor the EXAMINE commands include an untagged URLMECH reply. (Note, this is not the one mandated by the RESETKEY command.) AFAICT RFC 4467 does not require an URLMECH reply to SELECT or EXAMINE but without it clients have no way of knowing about authorization mechanisms other than INTERNAL. Now I know dovecot-2.2 supports only the INTERNAL mechanism at present so this is probably harmless, but still I think it's worthwhile to ask: Is the absence of the URLMECH reply intentional or an oversight? For comparison Apple's enhanced dovecot replies: c1 select inbox [...] * OK [URLMECH INTERNAL] Mechanisms supported c1 OK [READ-WRITE] Select completed.

[Dovecot] many SSH connexions with dsynx/SSH replication
by Emmanuel Dreyfus 06 May '13

06 May '13

Hi I am trying replication over dsync/ssh, as explained there: http://wiki2.dovecot.org/Replication I added the options below to dovecot.conf. It works, but it seems there is a new SSH connexion for each user, which is a bit overkill performance-wise. Since I sync as root, I guess there is a way of haing everything on the same SSH connexion? --- cut here --- mail_plugins = $mail_plugins notify replication service replicator { process_min_avail = 1 } dsync_remote_cmd = ssh -lroot %{host} doveadm dsync-server -u%u plugin { mail_replica = remote:root@mail1.example.net } service aggregator { fifo_listener replication-notify-fifo { user = dovecot } unix_listener replication-notify { user = dovecot } } service replicator { unix_listener replicator-doveadm { mode = 0600 } } service doveadm { inet_listener { port = 12345 ssl = yes } } doveadm_port = 12345 ssl_client_ca_file = /etc/openssl/certs/ca.crt doveadm_proxy_port = 0 --- cut here --- -- Emmanuel Dreyfus manu(a)netbsd.org

[Dovecot] dsyncing lazy_expunge namespace
by Angel L. Mateo 06 May '13

06 May '13

Hello, I'm in the process of migrating mailbox from one dovecot server running dovecot 2.1.9 with mailboxes stored in maildir format to a newer one running 2.1.16 with mailboxes stored in mdbox format. To migrate mailboxes I'm using dsync as explained at http://wiki2.dovecot.org/Tools/Dsync. The command I'm running in the newer server is: sudo dsync -o mailbox_list_index=no mirror -R -u <user> imapc: The mailbox of the user is correctly synced to the newer server, except the lazy_expunge namespace, which is not synced at all. The config in my old server is: namespace { # hidden = yes # list = no # Temporally, only for migration hidden = no list = yes location = maildir:~/Maildir/expunged prefix = BORRADOS. separator = . } and in the newer one is: namespace { hidden = yes list = no location = mdbox:%h/expunged:INDEX=/mail/indexes/%2Ln/%Ln/expunged prefix = BORRADOS/ separator = / } With a tcpdump I have checked that old servers list the namefolder, this is the IMAP dialog for an example user: * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE AUTH=PLAIN] Dovecot ready. 2 AUTHENTICATE PLAIN YW5nZWwubHVpcwBtYXN0ZXIAVkFzR293ZW0= 2 OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS THREAD=ORDEREDSUBJECT MULTIAPPEND UNSELECT CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS SPECIAL-USE QUOTA ACL RIGHTS=texk] Logged in 1 LIST "" "" * LIST (\Noselect) "."

[Dovecot] XFS vs EXT4 for mail storage
by Charles Marcus 05 May '13

05 May '13

Hello, I'm in the process of finalizing the spec for my new dovecot VM, and this is the last question I need to address... I've read until I'm just about decided on XFS, but I have no experience with it (been using reiserfs on my old box (@ 8 yrs old now), and never had a problem (knock on wood), but considering its current situation (little to no development support for reasons everyone is aware of), I've decided now is the time to switch. It came down to XFS or EXT4, and I like what I've read about XFS, but am unsure how to tune it (or even if I should). I've decided to use mdbox for storage (been using maildir), and will enable SIS for attachments. So, anyone (Stan?) have any suggestions? Should I go with EXT4? Or XFS with just the defaults? Or XFS with one or more tuned parameters? Appreciate any suggestions (including links to docs dealing with tuning XFS for my mail storage conditions that are written more at the layman level) or comments from anyone experienced using both... Thanks, -- Best regards, Charles

Re: [Dovecot] qmail-ldap LDA Delivery and sieve

Hi I used the below filter in my dovecot-ldap-userdb.conf file, user_attrs = homeDirectory=home, uidNumber=uid, gidNumber=gid user_filter = (&(objectClass=posixAccount)(|(mail=%u)(mailAlternateAddress=%u) (uid=%u))) This above filter was working fine for me, and it's delivering fine for all the domains. seive is also working fine. The "-d" in dovecot-lda will do userdb lookup with ldap.

[Dovecot] Dovecot has no understandable configuration any more
by forum 04 May '13

04 May '13

Hello, for many years i used an mailserver with dovecot V1 very satisfied! http://mailserver.decotrain.de/ One of the reasons to use dovecot was a simply configuration. Dovecot was the best choice for IMAP for me! Now i updated the server to Debian testing with dovecot 2.1.7. It's not possible for me to get a running authentication for virtual mail users! I recently found this mailing and have the same problem: http://www.dovecot.org/list/dovecot/2012-March/064181.html The documentation says *nothing* about my problem how to authenticate with mysql! http://wiki2.dovecot.org/VirtualUsers I can solve the problem only with try and error without a chance in this complex system. It's nice to have all this possibilites but they are not useful if not documented. There should be some clear examples for different scenarios to be found in your wiki. My problem at this time: I don't know how to configure the userdb to work with mysql authentification? All mail is running under the special user mail. dovecot.conf ============ disable_plaintext_auth = yes passdb { driver = sql # Path for SQL configuration file, see example-config/dovecot-sql.conf.ext args = /etc/dovecot/dovecot-sql.conf } userdb { driver = prefetch } first_valid_uid = 8 last_valid_uid = 8 first_valid_gid = 8 last_valid_gid = 8 mail_location = maildir:/srv/mail/%d/%n dovecot-sql.conf ================ driver = mysql connect = host=/var/run/mysqld/mysqld.sock dbname=... => WORKS! default_pass_scheme = SHA1 password_query = SELECT password, '/srv/mail/%d/%n' AS home, 'mail' AS uid, 'mail' AS gid FROM user WHERE username = '%n' AND domain = '%d' AND IMAP_allowed = 'YES' Errors ====== Apr 30 10:28:22 auth: Debug: client out: OK 1 user=xxxx@yyyy home=/srv/mail/yyyy/xxxx uid=mail gid=mail Apr 30 10:28:22 auth: Debug: master in: REQUEST 3163291649 5347 1 87066c907eef8f4e5ed71319b560dd2a Apr 30 10:28:22 auth: Error: prefetch(xxxx@yyyy,::1,<doTKyI/brgAAAAAAAAAAAAAAAAAAAAAB>): userdb lookup not possible with only userdb prefetch Apr 30 10:28:22 auth: Error: userdb(xxxx@yyyy,::1,<doTKyI/brgAAAAAAAAAAAAAAAAAAAAAB>): user not found from userdb prefetch Apr 30 10:28:22 auth: Debug: master out: NOTFOUND 3163291649 Apr 30 10:28:22 imap: Error: Authenticated user not found from userdb, auth lookup id=3163291649 (client-pid=5347 client-id=1) Apr 30 10:28:22 imap-login: Info: Internal login failure (pid=5347 id=1) (internal failure, 1 succesful auths): user=<karsten(a)dct.mine.nu>, method=PLAIN, rip=::1, lip=::1, mpid=5352, secured, session=<doTKyI/brgAAAAAAAAAAAAAAAAAAAAAB> I have no idea how to solve the problem and up to know i could not find an example with google.

[Dovecot] Accessing mail files not owned by imap login user
by PaulM47 03 May '13

03 May '13

Hi, I have managed to set up a 'maildir' based mail system using fetchmail and procmail that delivers sorted mail to folders /var/spool/mail/user1, ../user2 etc. 'user1', 'user2' etc. are real users but the mail system is run under logged in user 'mailserver'. The mail folders are owned by 'user1', 'user2' etc. but mail files, when delivered, are owned by 'mailserver'. I've been unable to find a way to change this behaviour :-( Dovecot is configured by adding the single line 'mail_location = maildir:/var/spool/mail/%u' to 'dovecot.conf', everything else is as installed. When I make an imap connection as 'user1' the logon is successful, the mail files are moved from ../new/ to ../cur/ but are invisible to the imap client. If I 'chown' the mail files to 'user1' they instantly become visible to the imap client. I gather from googling info on dovecot I can configure dovecot to allow 'user1', when logged in, to access the mail files owned by 'mailserver'. Is this simple to do, and if so how do I do it please ? Thanks PaulM -- View this message in context: http://dovecot.2317879.n4.nabble.com/Accessing-mail-files-not-owned-by-imap… Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] feature request: pipe for custom quota dict queries
by Jeff Gustafson 03 May '13

03 May '13

Just a followup to my previous post. I appears that a pipe for quota queries via dict is not supported right now. Because of the way we group things we need more flexibility. I'd like to propose that dovecot should support quota queries just like userdb dict queries. My expertise is not C, but I might try to poke around and see if I can make something work. ...Jeff

[Dovecot] sieve: deleteheader sometimes fails [bug]
by Daniel Piddock 03 May '13

03 May '13

Hi, We're using Dovecot 2.1.16 with Pigeonhole 0.3.4. Mail is delivered by exim4 to the dovecot LDA. Sometimes users are unable to delete headers. I've narrowed the problem down to preceding the deleteheader command with a query against the body. A simple example: """ require ["body", "editheader", "fileinto"]; if body :contains "!TEST!" { fileinto "INBOX.Trash"; stop; } deleteheader "Subject"; addheader "Subject" "Testing"; """ Putting the "deleteheader" above the "if body" causes it to be deleted correctly. Although I've used Subject in this example it happens for other headers. Cheers, Dan
