[Dovecot] 2.0: deliver run from multiple uids and configuration files
by Arkadiusz Miskiewicz 03 Jun '11

03 Jun '11

I'm trying to run deliver from exim transport in a way that it doesn't need to query userdb AND doesn't need to read configuration files. The problem is that config files are readable for root only and if I run deliver with multiple UIDs then I would have to allow reading config files for everyone. Of course that's not a option because configs contain database passwords and such stuff. I wonder if it is possible to avoid reading config files by deliver? The only solution I see it to run deliver via sudo which doesn't look nice. -- Arkadiusz Miśkiewicz PLD/Linux Team arekm / maven.pl http://ftp.pld-linux.org/

[Dovecot] LMTP/Sieve/sendmail path
by Andreas Schulze 03 Jun '11

03 Jun '11

Hello, I have a system using postfix multi instance feature. The first, main postfix-instance is a nullclient as suggested by http://www.postfix.org/MULTI_INSTANCE_README.html#split The second instance is for real use. Postfix receive mail and handover them to the dovecot lmtp server. Thats working. The lmtp server supports sieve. One account has activated a vacation rule. So while delivering a mail to this account, dovecot creates a new mail based on the vacation rules. *This one* fail. It is injected in the main postfix instance, which is wrong in this case. I tried to start dovecot with an additional environment MAIL_CONFIG=/etc/postfix-instance2 and enabled alternate_config_directories in main.cf of the first insance. ( http://www.postfix.org/postconf.5.html#alternate_config_directories ) I also configured the userdb to return an extrafield userdb_mail_config=/etc/postfix-instance2. But all produce strance postfix errors I never saw in my last 6 years as postfix-admin. Would it be possible to configure dovecot lmtp server to use an external smtp-server to submit new mails ? Any other Ideas ?

[Dovecot] Baffled after upgrade
by Bert Todger 02 Jun '11

02 Jun '11

Hello all, I have just upgraded my Fedora 13 system to F15. With it came a shiny new dovecot 2.0.13 (Details of dovecot -n below). The configuration is different from the dovecot 1.something that I had been used to with F13, but I managed to get it working and all was well... Without changing anything related to dovecot (as far as I know), after a reboot, dovecot stopped working. I did a bit of digging, upped the verbosity of logging and found this in the logs: =======8<================================================================= Jun 02 09:58:21 auth: Debug: passwd-file /etc/passwd.dovecot: Read 3 users Jun 02 09:58:21 auth: Debug: auth client connected (pid=16699) Jun 02 09:58:21 auth: Debug: client in: AUTH 1 PLAIN service=imap secured lip=192.168.2.2 rip=192.168.2.2 lport=993 rport=33960 Jun 02 09:58:21 auth: Debug: client out: CONT 1 Jun 02 09:58:21 auth: Debug: client in: CONT 1 AG1hcmsAaWxIYWFkSFA= Jun 02 09:58:21 auth: Debug: Loading modules from directory: /usr/lib/dovecot/auth Jun 02 09:58:21 auth: Debug: Module loaded: /usr/lib/dovecot/auth/libauthdb_ldap.so Jun 02 09:58:21 auth: Debug: Module loaded: /usr/lib/dovecot/auth/libdriver_sqlite.so Jun 02 09:58:21 auth: Debug: Module loaded: /usr/lib/dovecot/auth/libmech_gssapi.so Jun 02 09:58:21 auth: Debug: passwd-file /etc/passwd.dovecot: Read 3 users Jun 02 09:58:21 auth: Debug: pam(mark,192.168.2.2): lookup service=dovecot Jun 02 09:58:21 auth: Debug: pam(mark,192.168.2.2): #1/1 style=1 msg=Password: Jun 02 09:58:23 auth: Info: pam(mark,192.168.2.2): pam_authenticate() failed: Authentication failure (password mismatch?)

I have PLAIN passwords set in /etc/passwd.dovecot which it seems to be reading OK, my /etc/dovecot/conf.d/auth-passwdfile.conf.ext file contains just =========8<============================================= passdb { driver = passwd-file args = scheme=PLAIN username_format=%u /etc/passwd.dovecot } =========8<============================================= and nothing else. ...and as I said - it *was* working fine. I am puzzled by the reference to PAM authentication in the logs and in the dovecot -n output. Should I comment out all references to PAM? (in auth-system.conf.ext?) I and my family access mail through a variety of means, using Evolution on the home network, mobile devices (eg iPhone), webmail (using squirrelmail configured to access dovecot) and over ssh (using mutt). I don't necessarily want my (or their) email passwords to be the same as our PAM logon passwords (and at the moment they're not). So for me PLAIN has been the best solution up until now. What is my best (and simplest) solution?

[Dovecot] DOVECOT v2.0.11 using SIEVE not working
by Matt Mc Namara 01 Jun '11

01 Jun '11

Hi, I'm trying to get sieve working with dovecot. I seem to have everything enabled but my scripts done seem to work. both sieve-filter (2000) and sieve (4190) are running along with pop3 and imap. I have a simple script which checks the email address and moves it to a folder. I'm at a loss as to what to check next. Thanks in advance, Matt

[Dovecot] Client IP log variable for proxy/director setups?
by Kelsey Cummings 31 May '11

31 May '11

Timo - it would be very convenient if we could get a variable that held the real client ip for use in logging with director/proxy setups. It's clearly already passed around in client->user->remote_ip but at this point, I don't see anyway to get it into the logs and it would take me ages to figure out the Right place to add it since client->user doesn't seem to be available in client-common.c: get_var_expand_table(..). Perhaps I'm missing something obvious? -- Kelsey Cummings - kgc(a)corp.sonic.net sonic.net, inc. System Architect 2260 Apollo Way 707.522.1000 Santa Rosa, CA 95407

[Dovecot] PAM config problem...
by Juan Bernhard 30 May '11

30 May '11

Hi, I had some troubles with PAM configuration. I need to restrict imap access to some users (and allow pop3 to all). I followed the wiki example of using "args = %s" to use 2 pams configurations (one for imap and another for pop3) When I start the service, it starts, but when I try to auth its hangs Here is the log: May 26 15:16:09 claudia dovecot: master: Warning: Killed with signal 15 (by pid=15424 uid=0 code=kill) May 26 15:16:10 claudia dovecot: master: Dovecot v2.0.13 starting up May 26 15:16:24 claudia dovecot: auth: Debug: Loading modules from directory: /usr/local/lib/dovecot/auth May 26 15:16:24 claudia dovecot: auth: Fatal: pam: Unknown setting: %s May 26 15:16:24 claudia dovecot: master: Error: service(auth): command startup failed, throttling May 26 15:16:59 claudia dovecot: pop3-login: Error: Timeout waiting for handshake from auth server. my pid=15435, input bytes=0 Is this option working?

[Dovecot] recipient delimiters and virtual users
by Nick Edwards 30 May '11

30 May '11

Is there a known workaround for users who want to use the old recipient delimiter plus sign method of sorting their mail? eg: foo.bat +dovecot(a)example.com <foe.blow%2Bdovecot(a)example.com> This does not work with postfix/dovecot, but if we tell postfix/system-passwd to use the recipient_delimiter = + it works just like I recall sendmail did, but we no longer use local users only virtual dovecot LDA w/mysql. postfix appears to accept it testing by telnet, but then the message gets a new DSN generated saying no user, so dovecot LDA must not work by default with this. Postfix 2.8.3 Dovecot 1.2.17 MySQL 5.5.12 our postfix master.cf is dovecot unix - n n - - pipe flags=DRhu user=mail:mail argv=/usr/libexec/dovecot/deliver -e -d ${recipient}
