[Dovecot] recent master-settings.c and main.c changes breaks dovecot on my system
by Daniel 27 Mar '07

27 Mar '07

Hi! Compiled the latest cvs today, and noticed the changes in src/master/main.c and master-settings.c. With the versions 1.80.2.19 and 1.125.2.28 (respectively) I can not start dovecot, because it says: Fatal: dup2(stdin) failed: Bad file descriptor Error: imap dump-capability process returned 89 After reverting the patch: http://www.dovecot.org/list/dovecot-cvs/2007-March/008371.html everything is back to normal. My system is OpenBSD 4.0 and dovecot is recent cvs. Daniel

[Dovecot] Coredump in dovecot-auth on gss auth
by Dan Price 27 Mar '07

27 Mar '07

I've enabled the GSS code in dovecot, but our Kerberos nerds are complaining that it doesn't work :) I probably have the thing totally misconfigured (so don't worry about that part for now), but I do have a crash: Info: imap-login: Disconnected: rip=XXX.YYY.229.8, lip= XXX.YYY.17.59, TLS handshake Error: auth(default): gssapi(?,XXX.YYY.229.8): While acquiring service credentials: No credentials were supplied, or the credentials were unavailable or inaccessible Error: auth(default): gssapi(?,XXX.YYY.229.8): While acquiring service credentials: No principal in keytab matches desired name Info: imap-login: Disconnected: method=GSSAPI, rip=129.146.229.8, lip=XXX.YYY.17.59 Error: child 188558 (auth) killed with signal 11 Info: imap-login: Disconnected: method=PLAIN, rip=129.146.229.8, lip=XXX.YYY.17.59 The dovecot auth process SIGSEGV's and dies at login time (I think).

[Dovecot] Sync of read message status between squirrelmail and outlook express
by Mohd Ikhwan Abdullah 27 Mar '07

27 Mar '07

Hi, We have a Linux email server running CentOS 4.4. I have a scenario here. The users here use a mixture of outlook express and squirrel mail as their email client. The users download their mail into outlook express via pop3 but the have configured outlook express to leave a copy on the server for 7 days. 1. After downloading the mail into outlook express the users would read the mail and the mail would be set as 'READ' in outlook express. 2. Is there a way to configure dovecot so that the 'READ' status in outlook express is reflected on the message still stored on the server as well. Cause when they access via squirrel mail the message is still mark as 'UNREAD'. Any suggestions is very much appreciated. Thanks in advance.

Edlopen(/usr/local/lib/dovecot/imap/lib10_quota_plugin.so) failed: Could not load module /usr/local/lib/dovecot/imap/lib10_quota_plugin.so. System error: No such file or directory Error: imap dump-capability process returned 89 When i check the /usr/local/lib/dovecot/imap/lib10_quota_plugin.so i see that it is a link which is pointing /usr/local/lib/dovecot/lib10_quota_plugin.so . But there is no lib10_quota_plugin.so . I try compiling it on linux debian. I see that lib10_quota_plugin.so in it is proper place. I dont know what to do. Did i something wrong?

[Dovecot] LDA bouncing mails after upgrade
by Milan Holzäpfel 27 Mar '07

27 Mar '07

Hello, on my system, I have a copy of /usr/libexec/dovecot/deliver located in /usr/libexec/dovecot/postfix-deliver/deliver (only accessible to postfix and with SUID root permissions). If I happen to forget to update this copy after an upgrade of dovecot, the deliver LDA bounces mails: | Mar 22 20:29:20 host.example.org deliver(user(a)example.org): Module is for different version 1.0.rc27: /usr/lib/dovecot/lda/lib10_quota_plugin.so | Mar 22 20:29:20 host.example.org postfix/pipe[17344]: <ID>: to=<user(a)example.org>, relay=dovecot, delay=1.9, delays=1.5/0/0/0.35, dsn=5.3.0, status=bounced (Command died with status 89: "/usr/libexec/dovecot/postfix-deliver/deliver") Should I just set version_ignore=yes and remember myself to upgrade it, or could deliver return a code signaling "temporary failure", or should I rather make postfix interpret 89 as temporary failure? (don't know by heart whether that's possible). Regards, Milan -- Milan Holzaepfel <mail(a)mjh(d)name> <URL:http://mjh.name/> pub 4096R/C790FC23 EB8E 5E81 81E3 53A9 9B74 B895 5179 54C0 C790 FC23

[Dovecot] Odd error message
by Steven F Siirila 27 Mar '07

We are running Dovecot 1.0-rc27 and have run across what seems to be a fatal error (SIGSEGV) in the past few days (4 times total in past 6 days). It appears to have been 5 separate users, 5 separate remote IP addresses. Two of these have this format: Mar 26 15:13:10 myhostname dovecot: imap-login: Authenticate PLAIN failed: Don't send unrequested data: user=<rmtuser>, method=PLAIN, rip=10.9.9.9, lip=10.1.1.1, TLS The other three have this format: Mar 26 09:41:45 myhostname dovecot: imap-login: Authenticate PLAIN failed: Don't send unrequested data: method=PLAIN, rip=10.9.9.9, lip=10.1.1.1, TLS Here's the first one a bit more expanded, showing the SIGSEGV (signal 11): Mar 26 15:13:10 myhostname dovecot: auth(default): client in: AUTH 1 PLAIN service=IMAP secured lip=10.1.1.1 rip=10.9.9.9 Mar 26 15:13:10 myhostname dovecot: auth(default): client out: CONT 1 Mar 26 15:13:10 myhostname dovecot: auth(default): client in: CONT<hidden> Mar 26 15:13:10 myhostname dovecot: auth(default): pam(rmtuser,10.9.9.9): lookup service=IMAP Mar 26 15:13:10 myhostname dovecot: auth(default): client out: OK 1 user=rmtuser Mar 26 15:13:10 myhostname dovecot: auth(default): master in: REQUEST 675645 3333 1 Mar 26 15:13:10 myhostname dovecot: auth(default): passwd(rmtuser,10.9.9.9): lookup Mar 26 15:13:10 myhostname dovecot: auth(default): master out: USER 675645 rmtuser system_user=rmtuser uid=99999 gid=9999 home=/home/r/rmtuser Mar 26 15:13:10 myhostname dovecot: imap-login: Authenticate PLAIN failed: Don't send unrequested data: user=<rmtuser>, method=PLAIN, rip=10.9.9.9, lip=10.1.1.1, TLS Mar 26 15:13:10 myhostname dovecot: imap-login: Disconnected: user=<rmtuser>, method=PLAIN, rip=10.9.9.9, lip=10.1.1.1, TLS Mar 26 15:13:10 myhostname dovecot: child 3333 (login) killed with signal 11 What can I do to further diagnose this problem? -- Steven F.

[Dovecot] netapp/maildir/dovecot performance
by bofh list 26 Mar '07

26 Mar '07

We are seeing some poor performance recently that is focused around users with large mailboxes (100,000 message /INBOX, 80,000 message subfolders, etc). The performance problem manifests as very high system% utilization - basically iowait for NFS. There are two imap servers with plenty of horsepower/memory/etc. They are connected to a 3050c cluster via gig-e. Here are the mount options: rw,tcp,nfsvers=3,rsize=8192,wsize=8192,nosuid,nodev,soft,intr,noac,actimeo=0 I need to get this system% utilization brought down because it is starting to slowdown imap performance for other users (it goes up to 95% on a regular basis, with users that have folders with many messages). My thought is to try removing the noac option and bump up the actimeo value from 0 to 30. Unfortunately I don't have access to use a SLB to direct traffic to individual servers. My understanding is that the worst that can happen is index corruption (which will result in rebuilding them when it happens). Any thoughts? I'm running RC24.

[Dovecot] Unwanted INBOX. prefix issues
by Kevin Bowling 26 Mar '07

26 Mar '07

I have a strange problem. I installed Dovecot and had my trash folder and such in the root of my maildir, and everything was working great. I then installed SquirrelMail which created folders in with the INBOX. prefix. I manually removed these from the maildir, but the INBOX.Trash is still shown in the folder listing of Thunderbird. This leads to some strange behavior, such as the delete button not working. Is there a way I can reset the folder list, and take the INBOX.* items out? Any help would be appreciated. Regards, Kevin
