[Dovecot] Semi-OT: Backing up maildir
by Shayne Hardesty 15 May '06

15 May '06

We switched our mail server over from mbox to maildir a few months ago and couldn't be happier - the performance under normal load is incredible. However we now have a problem with backup.. Typically we would run tar on the mail server, sending its output to another server via ssh.. Like this: tar cfp - /home | gzip | ssh other.server (cd /backups && tar xfp -).. I have tried gzipping the stream on the source side, gzipping on the destination, and running without gzip, all three take an amazingly long time to complete (> 14 hours). Ours is a modest server with about 1300 users, about 300GB of mail total. The whole thing sits on hardware RAID-10, so I'm primarily guarding against a MAJOR hardware failure, a config blunder, or a hacker wiping out files. How do you guys back up your maildir? I've considered exporing the maildir with NFS and backing it up from another server.. Any opinions on that? Thanks, Shayne

[Dovecot] 1.0beta8 won't start: Fatal: Protocol imaps given more than once
by Mike Brudenell 15 May '06

15 May '06

Greetings - I've just built Dovecot 1.0beta8 and find it refuses to start. This under Solaris 10 on an Intel-based Sun system. The error message Dovecot displays (on standard error) in response to /usr/local/sbin/dovecot is Fatal: Protocol imaps given more than once I've checked through my configuration file and the only mention of "imaps" is here: # Protocols we want to be serving: # imap imaps pop3 pop3s protocols = imap imaps The same settings file worked OK with 1.0beta7. I've also tried using the standard dovecot-example.conf that comes with 1.0beta8 which has the "protocols" line commented out and, after adding appropriate settings for "ssl_cert_file" and "ssl_key_file", still have the same problem. I popped a few dubugging i_info() calls into src/master/main.c to try and see what was going on and the output was as follows: Info: set->protocols = >imap imaps< Info: imap: *fd = -1 Info: imaps: *fd = 0 Fatal: Protocol imaps given more than once The first line is displaying the value of the keywords in set->protocols The second and third are within the if/then/else sequence: the first for the "imap" keyword and the second for the "imaps" keyword. Then comes the fatal error, caused by the "fd" variable not being equal to -1 (it is "0" for "imaps") above. Changing the dovecot.conf file to read protocols = imap lets Dovecot start up OK. Changing it to protcols = imaps causes it to fail in the same way as before(!). Seems to be a problem with the initialisation of set->ssl_listen_fd therefore, as this should apparently be -1? Is this likely to be something I've got wrong (wouldn't have thought so as 1.0beta7 is happy with the same config file) or is there a problem in 1.0beta8?

[Dovecot] FSF - dovecot
by Matt 14 May '06

14 May '06

Will dovecot always be open FREE source for all? I am currently migrating my www.digipanel.com from Courier to dovecot as I think courier is overly complicated and a pain in the arse to manage all those files. anyways, I have dovecot IMAP working with MySQL auth but reading the Maildir each time takes up to 30 secs to complete. ANy ideas why? Maybe a dns resolve issue? how can I fix..

[Dovecot] problems with 1.0beta[78] on RHEL3
by alan premselaar 14 May '06

14 May '06

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I've been running 0.99.13 on RHEL 3 for over a year now and finally decided to upgrade to the 1.0 series. unfortunately, I only have one RHEL 3 machine which is my production machine. So, while doing all my preliminary testing I was doing so on a FC 3 machine. I got everything to a stage where I felt comfortable doing the upgrade but I'm running into some problems on the RHEL 3 system. if I download the tarball, it compiles without problem. If I download the cvs or the src.rpm then I get autoconf errors complaining about not supporting AC_CONFIG_HEADER but requiring AM_CONFIG_HEADER. it also complains that the installed version of autoconf is too old, although it's the latest package for RHEL 3 (which means it has the same version number as the original installed package but all the updates are back-ported to it, right?) anyways, that's all trivial as the source compiles. the problem I'm running into is this: the quota plugin is returning the following errors in the mail log: May 13 02:02:13 mail dovecot: POP3(real_user): dlopen(/usr/lib/dovecot/pop3/lib01_quota_plugin.so) failed: /usr/lib/dovecot/pop3/lib01_quota_plugin.so: undefined symbol: mount point_get and also: May 13 02:03:03 mail dovecot: IMAP(real_user): quotactl(Q_GETQUOTA, /dev/sdb1) failed: Invalid argument can anyone offer any assistance with this? oh yeah, one last thing. following the wiki, during the upgrade i renamed the .subscription files to subscription in each user's Maildir directory (oh yeah, i'm using maildir format) but, the subscription information wasn't persistant. anything else i need to be aware of related to that? thanks alan -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.1 (Darwin) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFEZMCtE2gsBSKjZHQRAjRVAKCPgSxLQzyJ7lrhCYBSxnVeTJixtgCaA8G5 NtAoCZZWpdetBLGQsA0llrU= =K+09 -----END PGP SIGNATURE-----

[Dovecot] SASL bind for LDAP
by Geert Jansen 13 May '06

13 May '06

Hi, would it be possible to add support for SASL binds to dovecot's LDAP userdb/passdb? This would be a nice feature as it would allow the use of SASL EXTERNAL binds to a local LDAP server, thereby removing the need for storing clear-text passwords in configuration files. Regards, Geert

[Dovecot] LDA Sieve feature request
by Luca Corti 13 May '06

13 May '06

Hello, In http://wiki.dovecot.org/LDA I read # If there is no user-specific Sieve-script, global Sieve script is # executed if set. #global_script_path = so you can set global_script_path and override it using a per user script. It would be nice if the per user scripts could be optionally run after (or before maybe?) the global script. Another nice thing would be per-virtualdomain sieve scripts, but I think this is much more difficult. What do you think? -- Luca Corti PGP Key ID 1F38C091 BOFH excuse of the moment: The Borg tried to assimilate your system. Resistance is futile.
