[Dovecot] Alert when quota is warning
by Nicolas Letellier 02 Apr '08

02 Apr '08

Hello. Is it exist a plugin to alert when a POP/IMAP account has a warning quota (like 90%)? Or, do you know a solution to do it? The alert could be an email sent. Thanks. - Nicolas.

[Dovecot] Outlook cant connect to POP server.
by "Fábio M. Catunda" 02 Apr '08

02 Apr '08

Hi, I'm having a weir situation with MS Outlook and dovecot. I'm using POP for some users, some can connect, others cant. With tcpdump I got this packet coming from client to server: 2008-03-31 18:30:20.913718 IP (tos 0x0, ttl 128, id 1082, offset 0, flags [DF], proto: TCP (6), length: 48) 192.168.12.9.1072 > 192.168.5.124.110: S, cksum 0x90db (correct), 2564735473:2564735473(0) win 65535 <mss 1460,nop,nop,sackOK> E..0.:@...c.... ...|.0.n........p............... But the server never give an answer. I don't have any idea why the server do not answer, in error.log and info.log I got nothing. Dovecot version: 1.0.rc15-2etch3 (Debian package) And those are the workarrounds that I enabled: pop3_client_workarounds = outlook-no-nuls oe-ns-eoh I'm kind of lost, any tip is appreciated! Thanks!

[Dovecot] v1.1.rc4 released
by Timo Sirainen 01 Apr '08

01 Apr '08

http://dovecot.org/releases/1.1/rc/dovecot-1.1.rc4.tar.gz http://dovecot.org/releases/1.1/rc/dovecot-1.1.rc4.tar.gz.sig I didn't have time/energy to fix everything I wanted, so it'll probably be a few more RCs left until v1.1.0. This is anyway an important release, because it fixes two buffer overflows in search code which have been in all v1.1 releases (but not v1.0). Really stupid mistakes, I must have been tired or something when writing the code.. Anyway I now added code to notice these kind of buffer overflows when they happen (if --enable-debug is used), so hopefully these will be the last ones. * Fixed two buffer overflows in str_find_init(). It was used by SEARCH code when searching for headers or message body. Added code to catch these kind of overflows when compiling with --enable-debug. Found by Diego Liziero. + LDAP: Added debug_level and ldaprc_path settings (OpenLDAP-only) + Squat: Added fts_squat = partial=n full=m settings. See the wiki. - dbox metadata updating fixes. - quota: backend=n didn't work - SEARCH RECENT may have returned non-recent messages if index files were created by v1.0. - If mailbox was opened as read-only with EXAMINE, STOREs were permanently saved. - LDAP: Templates were somewhat broken (by richs at whidbey.net)

[Dovecot] deliver tries to compile already compiled sieve script
by Alexander Prinsier 01 Apr '08

01 Apr '08

Hello, I'm trying to setup dovecot with sieve support in a way where all sieve scripts are precompiled. All sieve scripts are in /var/cache/sieve/. I believe I discovered a bug here. I describe below how to reproduce it. Dovecot and the user that deliver runs as do not have write permission in /var/cache/sieve/. h01:/var/cache/sieve# ls -la total 16 drwxr-xr-x 2 ecp ecp 4096 Mar 31 21:32 . drwxr-xr-x 10 root root 4096 Mar 31 20:14 .. -rw-r--r-- 1 ecp ecp 88 Mar 31 21:32 mailtest1(a)domain.com.sieve -rw-r--r-- 1 ecp ecp 132 Mar 31 21:32 mailtest1(a)domain.com.sievec When deliver runs it logs this error: open(/var/cache/sieve/mailtest1(a)domain.com.sievec.tmp) failed: Permission denied This indicates deliver tries to compile the script, even though the compiled version already is there. To verify I tested another case. I make the compiled script immutable and I did a chmod 777 on /var/cache/sieve/. Then deliver logs this error: rename(/var/cache/sieve/mailtest1(a)domain.com.sievec.tmp, /var/cache/sieve/mailtest1(a)domain.com.sievec) failed: Operation not permitted And deliver created the file mailtest1(a)domain.com.sievec.tmp. Some relevant pieces of my dovecot.conf: protocol lda { mail_plugins = quota cmusieve ... } plugin { sieve = /var/cache/sieve/%u.sieve } Anyone can help me? Is this an error on my end, or really a bug? Alexander

[Dovecot] Dovecot 1.1rc3 crashes with Dbox + imap_quota plugin

Version: Dovecot v1.1.rc3 OS: CentOS 5 running in OpenVZ CPU: x86_64 Was running fine with maildir and decided to get dbox a try.

In mail_log plugin I wanted to print the committed UIDs. I changed mail_log_transaction_commit() to: { ... ret = lbox->super.transaction_commit(t, uid_validity_r, first_saved_uid_r, last_saved_uid_r); if (0 == ret) { i_info("uid_validity=%u, first_uid=%u, last_uid=%u", *uid_validity_r, *first_saved_uid_r, *last_saved_uid_r); } return ret; } the result was: Apr 1 14:59:37 ha-test1 deliver(test1(a)test.com): uid_validity=1202218363, first_uid=1202218363, last_uid=1202218363 These values are equal to the UID validity. After changing mailbox_transaction_commit() as described above, I got correct values: Apr 1 15:09:50 ha-test1 deliver(test1(a)test.com): uid_validity=1202218363, first_uid=139, last_uid=139 Ron ____________________________________________________________________________________ You rock.

[Dovecot] Segfault with soft disk quota
by Tim Boyer 01 Apr '08

01 Apr '08

RHEL 5.1, dovecot 1.0.rc15 on a x86 system. dovecot -n says [root@dg mail]# dovecot -n # /etc/dovecot.conf protocols: pop3 pop3s login_dir: /var/run/dovecot/login login_executable: /usr/libexec/dovecot/pop3-login login_process_size: 64 first_valid_uid: 100 mail_executable: /usr/libexec/dovecot/pop3 mail_plugin_dir: /usr/lib64/dovecot/pop3 auth default: passdb: driver: pam userdb: driver: passwd I had one user whose Outlook kept giving disconnection problems. I looked at the logs, and found this: Mar 31 14:05:31 dg.denmantire.com dovecot: POP3(bfarner): open(/home/bfarner/Mail/.imap/INBOX/.temp.dg.denmantire.com.4668.564b08eac94 4fe4a) failed: Disk quota exceeded Mar 31 14:05:31 dg.denmantire.com dovecot: POP3(bfarner): Fixed index file /home/bfarner/Mail/.imap/INBOX/dovecot.index: log file sync pos 2,115528 -> 3, 24 Mar 31 14:05:31 dg.denmantire.com dovecot: POP3(bfarner): Fixed index file /home/bfarner/Mail/.imap/INBOX/dovecot.index: messages_count 3 -> 0 Mar 31 14:05:31 dg.denmantire.com dovecot: pop3-login: Login: user=<bfarner>, method=PLAIN, rip=192.168.0.37, lip=192.168.0.2 Mar 31 14:05:31 dg.denmantire.com pop3[4668]: segfault at 0000000000000000 rip 00000000004452e8 rsp 00007fff56ccd460 error 4 Mar 31 14:05:31 dg.denmantire.com dovecot: child 4668 (pop3) killed with signal 11 Strange thing is - he's over disk quota, but just over the soft quota - nowhere close to the hard quota. Easy for me to fix, but I figured I'd also submit it as a bug. I don't follow the list so if you need any more info, please copy my email on the reply.

[Dovecot] Bug in db-ldap.c with Dovecot1.1rc3
by richs＠whidbey.net 01 Apr '08

01 Apr '08

If using LDAP as a userdb with a "quota_rule" configured, the order of the LDAP entry can distort userdb results, depending on where the quota attribute is found. For instance, with this "dovecot-ldap.conf" snippet: user_attrs = homeDirectory=home,uidNumber=uid,gidNumber=gid,quotaKb=quota_rule=*:storage=%$ And this example LDAP entry: dn: uid=testuser,ou=people,dc=domain.com uid: testuser homeDirectory: /mail/testuser gidNumber: 100 cn: testuser quotaKb: 20480 uidNumber: 121212 When db_ldap_result_iterate_next_all() runs, "quotaKb" is encountered, which causes "ctx->template" to be set. On the next iteration, "uidNumber" is encountered, but "ctx->template" is still set, causing the "uid" value to be prepended with "*:storage=". This is reflected by an error in the log as: Invalid UID value '*:storage=121212' This can be fixed by adding a line after 1118 to src/auth/db-ldap.c: ctx->template = NULL; Hope this is helpful to someone, -Rich
