[Dovecot] multiple instances of dovecot on one machine
by Marshal Newrock 23 Mar '07

23 Mar '07

I was trying to run two instances of dovecot on the same machine, each listening on a single IP. The problem I ran into was that each time one was started or restarted, the other stopped responding. I saw the following in the logs: Mar 23 00:02:27 sentinel dovecot: Dovecot v1.0.rc27 starting up Mar 23 00:02:27 sentinel dovecot: Socket already exists: /var/run/dovecot/dict-server After I saw that, I commented out the dict section and quota from the plugins. The second line disappeared, but I could still only get one dovecot listening at a time. In the end, I went back to a single dovecot listening on all IP's, and found another way to do what I was trying to do, so all is still working for me. I'm guessing I'm the first person to try to run two dovecots on one machine. Actually, I should clarify: there was also a third, listening to none on localhost, but there only for the lda process. The auth socket was set to /var/run/dovecot/auth-master. And this also was not accepting connections while the others were running. -- Marshal Newrock Ideal Solution, LLC - http://www.idealso.com

[Dovecot] Possible bug with removing e-mail when user over fs quota
by Qweb - Yavuz Aydin 23 Mar '07

23 Mar '07

Dear list, I don't know if this is by design or possibly a bug, but there is a difference when removing e-mail when a user is over filesystem quota when indexing is on or off. All is working fine on our servers when indexing is on, users can remove then purge e-mail when over quota, but when we turn off indexing (by setting INDEX=MEMORY) it doesn't work. Users can remove, but not purge. And after a reload of the page the e-mail is there again. We are using Dovecot 1.0.rc15 on Debian Sarge (through backports.org) with mboxes. We have set up the configuration of dovecot regarding quota's according to http://wiki.dovecot.org/Quota/FS Unfortunately I don't have time to try this on the latest version, but is there anyone out there willing to try? -- Best regards, Yavuz Aydin Qweb Internet Services

[Dovecot] maildirsize problem?
by Alan Mosca [Aluminati] 23 Mar '07

23 Mar '07

Hello all, Recently I have received a few complaints from users that their quota was being reported wrong. This seems to have started when I switched to quota=maildir and ignore=Trash (did both at the same time). The main reported problem is that maildirsize is not correctly updated when they delete messages. My personal hypothesis is something like this: - User moves to Trash - Trash is ignored so it is not marked on the maildirsize (?) - User purges trash - Trash is still ignored so it is still not marked (?) Resulting in a buildup of errors in the maildirsize file. Would it be a good idea to mark the maildirsize file when a file is moved to an ignored folder? That could though potentially lead to people just moving to trash instead of deleting. Thank you guys and keep up the good work! -- Alan Mosca Systems Administrator Aluminati Network Group

[Dovecot] Timeout while logging in
by Kevin Richter 23 Mar '07

23 Mar '07

Hi, sometimes there is a timeout, while logging in. Dovecot-rc24 Dovecot uses PAM, PAM uses a LDAP server. Solaris 10 The log, if everything is ok: auth(default): client in: AUTH 1 PLAIN service=POP3 secured lip=x.x.x.x rip=x.x.x.x resp= auth(default): client out: CONT 1 auth(default): client in: CONT<hidden> auth(default): client out: OK 1 user=ssal0041 auth(default): master in: REQUEST 453 4779 1 auth(default): master out: USER 453 ssal0041 system_user=ssal0041 uid=3092 gid=1100 home=/home/ss pop3-login: Login: user=<ssal0041>, method=PLAIN, rip=x.x.x.x, lip=x.x.x.x, TLS POP3(ssal0041): Effective uid=3092, gid=1100 POP3(ssal0041): mbox: data=/home/ssal0041/mail/:INBOX=/var/mail/ssal0041 POP3(ssal0041): mbox: root=/home/ssal0041/mail, index=/home/ssal0041/mail, inbox=/var/mail/ssal0041 POP3(ssal0041): Disconnected: Logged out top=0/0, retr=0/0, del=0/0, size=0 The log, if a timeout occures: auth(default): client in: AUTH 1 PLAIN service=POP3 secured lip=x.x.x.x rip=x.x.x.x resp= auth(default): client out: CONT 1 auth(default): client in: CONT<hidden> auth(default): client out: OK 1 user=ssal0041 auth(default): master in: REQUEST 454 4770 1 auth(default): master out: USER 454 ssal0041 system_user=ssal0041 uid=3092 gid=1100 home=/home/ss pop3-login: Login: user=<ssal0041>, method=PLAIN, rip=x.x.x.x, lip=x.x.x.x, TLS The rest is missing.

Re: [Dovecot] deliver to subfolder with dovecot's LDA

[Dovecot] I wrote a managesieve server for Dovecot
by Neale Pickett 22 Mar '07

22 Mar '07

I have written a managesieve server from scratch in Python. I did just enough work to get it working with avelsieve (the squirrelmail plugin), smartsieve, and KDE's sieve kioplugin. It supports the entire Internet draft. Since I didn't have a working sieve server to compare against, I'm not sure if it's 100% compatible with timsieved. Client applications seem to work okay anyway. I wrote it in such a way as to decouple how authentication is carried out and how sieve scripts are actually stored, so you could for instance modify this to work with SASL and Exim. Currently it only has code for PAM and Dovecot's LDA, because I run Postfix :). TLS support is in the code but disabled because I had problems writing a unit test for it. All my connections are from localhost anyway. http://woozle.org/~neale/repos/pysieved if anyone is interested. I haven't looked closely at Stephan Bosch's managesieve server in C but I do want to acknowledge that he has written a C managesieve server that currently exists as a patch to the Dovecot source code. People looking for a managesieve implementation in C are encouraged to try his patch out: http://sinas.rename-it.nl/~sirius/ Neale

[Dovecot] tilde in mbox:, when used in non-system user db
by Michal Soltys 22 Mar '07

22 Mar '07

Originally I've thought that this is related to INBOX field, but it turned out it happens only when you specify mbox. Consider following passwd-file: testms::10000:10000:imap,,,:/home/vmail/ppgk.com.pl/testms/./::userdb_mail=mbox:~/Mail:INBOX=/home/vmail/ppgk.com.pl/%u/inbox or following line from userdb static: args = uid=10000 gid=10000 home=/home/vmail/ppgk.com.pl/%u/./ mail=mbox:~/Mail:INBOX=/home/vmail/ppgk.com.pl/%u/inbox In both cases, in user's directory, there will be an empty ~/Mail directory created, in addition to Mail and inbox. No idea about how sql or ldap would behave here, but global mail_location from dovecot.conf doesn't suffer from this issue (~ was expanded properly in ktrace dump). Chroot specification (/./) doesn't matter here. If I change mbox:~/Mail:INBOX=..... to mbox:/home/vmail/ppgk.com.pl/%u/Mail:INBOX=~/inbox then everything will be fine - no extra '~' dir. Thus my assumption it's not INBOX field related. Looking at ktrace, it seems that imap process is checking for the existence of ~/Mail, without expanding tilde. Then quite a bit later, it creates Mail as a "side effect" of creating Trash subdirectory. Relevant fragments: 1853 imap CALL mkdir(0x8a79b100,0x1f8) 1853 imap NAMI "~/Mail" 1853 imap RET mkdir -1 errno 2 No such file or directory 1853 imap CALL sigprocmask(0x1,0xffffffff) 1853 imap RET sigprocmask 0 1853 imap CALL mprotect(0x3c0ec000,0x1000,0x3) 1853 imap RET mprotect 0 1853 imap CALL mprotect(0x3c0ec000,0x1000,0x1) 1853 imap RET mprotect 0 1853 imap CALL sigprocmask(0x3,0) 1853 imap RET sigprocmask -65793/0xfffefeff 1853 imap CALL mkdir(0x8a79b108,0x1f8) 1853 imap NAMI "~" 1853 imap RET mkdir 0 1853 imap CALL mkdir(0x8a79b100,0x1f8) 1853 imap NAMI "~/Mail" 1853 imap RET mkdir 0 and 1853 imap CALL stat(0x8a79b180,0xcfbeb5c0) 1853 imap NAMI "/home/vmail/ppgk.com.pl/testms/Mail/Trash" 1853 imap RET stat -1 errno 2 No such file or directory 1853 imap CALL stat(0x8a79b1b0,0xcfbeb600) 1853 imap NAMI "/home/vmail/ppgk.com.pl/testms/Mail/Trash" 1853 imap RET stat -1 errno 2 No such file or directory 1853 imap CALL mkdir(0x8a79b1e0,0x1f8) 1853 imap NAMI "/home/vmail/ppgk.com.pl/testms/Mail" 1853 imap RET mkdir 0 1853 imap CALL open(0x8a79b1b0,0xa02,0x1b0) 1853 imap NAMI "/home/vmail/ppgk.com.pl/testms/Mail/Trash" 1853 imap RET open 7 My configuration is prtty much the same as previously: openbsd 3.9, i386, dovecot 1.0-rc27 (latest nightly, but the same happened in stock 1.0rc27) dovecot.userdb: testms::10000:10000:imap,,,:/home/vmail/ppgk.com.pl/testms/./::userdb_mail=mbox:~/Mail:INBOX=/home/vmail/ppgk.com.pl/%u/inbox dovecot.passdb: testms:{PLAIN}test: base_dir: /var/dovecot/ protocols: imap imaps pop3 pop3s ssl_listen: * ssl_ca_file: /etc/ssl/cert_bundle.pem ssl_cert_file: /etc/ssl/ca_ppgk/certs/fetch_crt.pem ssl_key_file: /etc/ssl/ca_ppgk/private/fetch_key.pem verbose_ssl: yes login_dir: /var/dovecot/login login_executable(default): /usr/local/libexec/dovecot/imap-login login_executable(imap): /usr/local/libexec/dovecot/imap-login login_executable(pop3): /usr/local/libexec/dovecot/pop3-login login_greeting: Dovecot IMAP server ready. login_greeting_capability(default): yes login_greeting_capability(imap): yes login_greeting_capability(pop3): no valid_chroot_dirs: /var/mail:/home/regular:/home/vmail verbose_proctitle: yes first_valid_uid: 1999 first_valid_gid: 10 mail_location: mbox:~/Mail:INBOX=/var/mail/%u mail_debug: yes fsync_disable: yes lock_method: fcntl maildir_copy_with_hardlinks: yes mbox_read_locks: fcntl mbox_write_locks: fcntl mail_executable(default): /usr/local/libexec/dovecot/imap mail_executable(imap): /usr/local/libexec/dovecot/imap mail_executable(pop3): /usr/local/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/local/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/lib/dovecot/imap mail_plugin_dir(pop3): /usr/local/lib/dovecot/pop3 imap_client_workarounds(default): outlook-idle delay-newmail imap_client_workarounds(imap): outlook-idle delay-newmail imap_client_workarounds(pop3): outlook-idle pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %08Xu%08Xv pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh auth default: mechanisms: plain login verbose: yes debug: yes passdb: driver: passwd-file args: /etc/dovecot.passdb passdb: driver: bsdauth userdb: driver: passwd-file args: /etc/dovecot.userdb userdb: driver: passwd socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master:
