BUG: segfault in auth when user listed multiple times in LDAP
by Laszlo Toth 03 Jul '14

03 Jul '14

Hi, I think I found a bug in the auth module. It can be triggered when the userdb is in LDAP and an user is found multiple times in LDAP. Dovecot version 2.2.10 (from ATrpms Testing) running on CentOS 6.5 x64. Jun 27 10:34:34 server dovecot: auth: Debug: ldap(USER): user search: base=dc=linguamatics,dc=com scope=subtree filter=( & (uid=user) (| (&(objectClass=posixAccount)(|(employeeType=staff)(employeeType=guest))) (objectClass=account) ) ) fields=uid Jun 27 10:34:34 server kernel: auth[15916]: segfault at 8 ip 00007f45e5aa9bef sp 00007fff5b17e210 error 4 in libauthdb_ldap.so[7f45e5aa4000+a000] Jun 27 10:34:34 server dovecot: auth: Error: ldap(user): LDAP search returned multiple entries Jun 27 10:34:34 server dovecot: auth: Debug: ldap(user): no fields returned by the server Jun 27 10:34:35 server abrtd: Directory 'ccpp-2014-06-27-10:34:34-15916' creation detected Jun 27 10:34:35 server abrt[16137]: Saved core dump of pid 15916 (/usr/libexec/dovecot/auth) to /var/spool/abrt/ccpp-2014-06-27-10:34:34-15916 (2863104 bytes) Jun 27 10:34:35 server dovecot: doveadm(user): Error: userdb lookup(user): Disconnected unexpectedly Jun 27 10:34:35 server dovecot: doveadm(user): Error: sync: User lookup failed: Internal error occurred.

Crash in service imap with version 2.2.13

Hi, yesterday I upgraded to version 2.2.13 under Debian Squeeze. Since today morning sometimes my logfile shows the folling error: ..

Bug in quota_get_status
by Franz Knipp 03 Jul '14

03 Jul '14

Hi, the configuration option lmtp_rcpt_check_quota = yes didn't work, so I traced down the problem: quota_get_status (quota_storage.c:89) calls quota_test_alloc (quota.c:1352) with size = 0 bytes, which leads always to a FALSE result in quota_is_over (quota.c:1305). I've fixed the function quota_is_over by considering ctx->bytes_over and ctx->count_over. See the included patch. Kind regards, Franz -- Franz Knipp, +43 664 3980169 qnipp GmbH, Hauptstraße 54, 7064 Oslip, Österreich http://qnipp.com http://qnipp.com/qnipp.vcf

Mailboxes are in Maildir format. Any good backup tips? Had success with version control?
by deoren 02 Jul '14

02 Jul '14

I'm still pretty new to running a mail server, but one thing I've come to appreciate over the years is a good backup strategy. Since I have always run my own servers for practice and for personal use I don't have access to Enterprise backup solutions. Because of that I usually just fall back to scripts and tarballs and offload the content on a regular basis. Right now I'm using LVM snapshots + tarballs for daily backups, but I'd like to get better coverage for incremental changes that occur throughout the day. The size of existing content is low, but (small) changes are frequent. I went with Maildir format because based on my reading it is referred to as time tested and corruption resistant. Because individual emails are stored as separate files this also leads me to believe that a version control system (Git, SVN) would allow for easy point in time restores. I'm also going to research the GNU tar utility's support for incremental archives as that sounds promising. Suggestions and warnings are most welcome. Thanks!

doveadm director userdb
by G H 02 Jul '14

02 Jul '14

How do you configure an iterate_query SQL lookup for the doveadm director? I tried: service director { userdb { ... } } but userdb is not a valid stanza for director. I do not have a default userdb stanza, all my userdb definitions are specified in service imap/lda/lmtp blocks. Thanks. G H

Greetings, I'm getting reports from a user who's reading and deleting mail on Thunderbird, but read flags and deletions don't show up in his Android phone. He's using the native Android mail app with the newest Android OS. My question is, where do I start with troubleshooting this kind of issue? Thanks for anyone's insight here.
