[Dovecot] Deliver and file system quota
by Rainer Frey 13 Nov '09

13 Nov '09

Hi, what is the quota plugin for deliver supposed to do when using fs quota? With IMAP, and not using noenforcing, a user that is over Soft limit can't copy mails. With deliver, the mail is delivered normally. When hard limit is exceeded, there is an error "rejected: Not enough disk space", just like when I don't use the plugin in lda. Even the lda setting "quota_full_tempfail = yes" works without the plugin configured in lda section. So is there any effect of the quota plugin in lda with file system quota? Thanks Rainer

[Dovecot] sieve files wont get parsed/compiled using cmusieve
by Moritz Krinke 13 Nov '09

13 Nov '09

Hello, im trying to get sieve up and running, but apparently my sieve rules file doesnt get parsed / compiled and i cant see any errors in my logfile which would point me to the problem. im using ubuntu 9.10 (and the dovecot packages from it), dovecot version is 1.1.11. in the protocol lda section of the config file i have added: mail_plugins = cmusieve mail_plugin_dir = /usr/lib/dovecot/modules/lda and in the plugins section: sieve = /var/vmail/%d/%n/.dovecot.sieve sieve_dir = /var/vmail/%d/%n/sieve root@mail:/# l /usr/lib/dovecot/modules/lda/lib90_cmusieve_plugin.* -rw-r--r-- 1 root root 247470 2009-10-15 06:38 /usr/lib/dovecot/modules/lda/lib90_cmusieve_plugin.a -rw-r--r-- 1 root root 1038 2009-10-15 06:37 /usr/lib/dovecot/modules/lda/lib90_cmusieve_plugin.la -rw-r--r-- 1 root root 141384 2009-10-15 06:38 /usr/lib/dovecot/modules/lda/lib90_cmusieve_plugin.so in /var/vmail/%d/%n/ i have a dir "sieve", containing a sieve rule file and a symlink to it: ls -la .dovecot.sieve lrwxrwxrwx 1 root root 21 2009-11-07 17:14 .dovecot.sieve -> sieve/roundcube.sieve ls -la sieve/ total 16 drwxrw-rw- 3 vmail mail 4096 2009-11-07 17:02 . drwxrw---- 20 vmail mail 4096 2009-11-07 17:20 .. -rwxrw-rw- 1 vmail mail 359 2009-11-07 17:02 roundcube.sieve as i understand the documentation there should be a ".dovecot.sievec" file after the first mail arrived. But there isnt. There also is nor err file . Since the dovecot user is in the group "mail", deliver should have rw-access to the sieve file/directory. The Upload of the sieve rule via dovecots managesieve did work as expected. Would be great if anyone had an idea what/where to check next...? ;-) Thanks, Moritz

[Dovecot] UTF-8 mailbox names in filesystem
by Timo Sirainen 13 Nov '09

13 Nov '09

Currently mailbox names are stored in IMAP's modified-UTF-7 format in filesystem. I was wondering about changing this in v2.0. The default would still be to use mUTF-7 in filesystem, but just adding :UTF8 or something to mail_location could enable UTF-8. Any thoughts? Could this be dangerous somehow? UTF-8 enables a lot of weird characters, perhaps no one really wants to see them on filesystem since there's no way to type the characters? But for small systems this probably isn't a problem.

[Dovecot] Postfix and Dovecot SASL
by Rene Bakkum 12 Nov '09

12 Nov '09

Hello all, I am struggeling to get my Dovecot SASL to work within postfix. I have used the configuration example listed on the main-site of dovecot and it basically isn't giving me any success at all. I am probably missing something easy, but after spending a few days testing and walking through everything I could think about I thought figured it was better to ask :) Hope someone can point me to the right direction. My setup is that I have installed Ubuntu 9.04 (64bit), postfix and dovecot linked to a MySQL database. The services are using maildirs which are stored locally (no NFS). Postfix is using the LDA from dovecot to deliver the mail and dovecot is used for IMAP and POP3. This is working and no problems at all so far. The problem starts when I just want to enable the SASL authentication from Dovecot. I used the 'guide' posted on http://wiki.dovecot.org/HowTo/PostfixAndDovecotSASL When I try to telnet to port 25 (smtp) than I doesn't looks like the SASL is working... 220 mail003 ESMTP Postfix (Ubuntu) ehlo localhost 250-mail003 250-PIPELINING 250-SIZE 10240000 250-VRFY 250-ETRN 250-STARTTLS 250-ENHANCEDSTATUSCODES 250-8BITMIME 250 DSN Anything I missed in my configuration from either postfix/dovecot? root@mail003:/etc/postfix# dovecot --version 1.1.11 root@mail003:~# dpkg-query -l postfix +++-==============-==============-============================================ ii postfix 2.5.5-1.1 High-performance mail transport agent Here are my configurations of both: root@mail003:/etc/postfix# dovecot -n # 1.1.11: /etc/dovecot/dovecot.conf # OS: Linux 2.6.28-16-server x86_64 Ubuntu 9.04 ext4 log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap pop3 imaps pop3s managesieve ssl_cert_file: /etc/ssl/certs/ssl-mail.pem ssl_key_file: /etc/ssl/private/ssl-mail.key ssl_cipher_list: ALL:!LOW:!SSLv2:ALL:!aNULL:!ADH:!eNULL:!EXP:RC4+RSA:+HIGH:+MEDIUM login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login login_executable(managesieve): /usr/lib/dovecot/managesieve-login login_greeting_capability(default): yes login_greeting_capability(imap): yes login_greeting_capability(pop3): no login_greeting_capability(managesieve): no mail_max_userip_connections(default): 10 mail_max_userip_connections(imap): 10 mail_max_userip_connections(pop3): 3 mail_max_userip_connections(managesieve): 10 mail_privileged_group: mail mail_uid: 5000 mail_gid: 5000 mail_location: maildir:/home/vmail/%d/%n/.Maildir mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_executable(managesieve): /usr/lib/dovecot/managesieve mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 mail_plugin_dir(managesieve): /usr/lib/dovecot/modules/managesieve imap_client_workarounds(default): outlook-idle delay-newmail imap_client_workarounds(imap): outlook-idle delay-newmail imap_client_workarounds(pop3): imap_client_workarounds(managesieve): pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh pop3_client_workarounds(managesieve): sieve_storage(default): sieve_storage(imap): sieve_storage(pop3): sieve_storage(managesieve): ~/sieve sieve(default): sieve(imap): sieve(pop3): sieve(managesieve): ~/.dovecot.sieve auth default: mechanisms: plain login passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: sql args: /etc/dovecot/dovecot-sql.conf socket: type: listen client: path: /var/spool/postfix/private/dovecot-auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 384 user: vmail group: vmail root@mail003:/etc/postfix# postconf | grep sasl broken_sasl_auth_clients = yes cyrus_sasl_config_path = lmtp_sasl_auth_cache_name = lmtp_sasl_auth_cache_time = 90d lmtp_sasl_auth_enable = no lmtp_sasl_auth_soft_bounce = yes lmtp_sasl_mechanism_filter = lmtp_sasl_password_maps = lmtp_sasl_path = lmtp_sasl_security_options = noplaintext, noanonymous lmtp_sasl_tls_security_options = $lmtp_sasl_security_options lmtp_sasl_tls_verified_security_options = $lmtp_sasl_tls_security_options lmtp_sasl_type = cyrus proxy_write_maps = $smtp_sasl_auth_cache_name $lmtp_sasl_auth_cache_name send_cyrus_sasl_authzid = no smtp_sasl_auth_cache_name = smtp_sasl_auth_cache_time = 90d smtp_sasl_auth_enable = no smtp_sasl_auth_soft_bounce = yes smtp_sasl_mechanism_filter = smtp_sasl_password_maps = smtp_sasl_path = smtp_sasl_security_options = noplaintext, noanonymous smtp_sasl_tls_security_options = $smtp_sasl_security_options smtp_sasl_tls_verified_security_options = $smtp_sasl_tls_security_options smtp_sasl_type = cyrus smtpd_recipient_restrictions = reject_unknown_sender_domain, reject_unknown_recipient_domain, reject_unauth_pipelining, permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination smtpd_sasl_auth_enable = yes smtpd_sasl_authenticated_header = yes smtpd_sasl_exceptions_networks = smtpd_sasl_local_domain = $myhostname smtpd_sasl_path = private/dovecot-auth smtpd_sasl_security_options = noanonymous smtpd_sasl_tls_security_options = $smtpd_sasl_security_options smtpd_sasl_type = dovecot Any ideas?

[Dovecot] multiple connections per imap/pop3 process in 2.0
by Mike Abbott 12 Nov '09

12 Nov '09

When I set this in master.conf: service imap { service_count = 5 } I see this error when two imap users log in: Nov 11 16:54:16 server dovecot[5432]: imap-login: Login: user=<user1>, method=PLAIN, rip=10.100.0.84, lip=10.80.0.163, pid=5573 Nov 11 16:54:31 server dovecot[5432]: imap-login: Login: user=<user2>, method=PLAIN, rip=::1, lip=::1, secured, pid=5573 Nov 11 16:54:31 server dovecot[5432]: imap(pid 5573 user user2): Fatal: setgid(2002) failed with euid=2001(user1), gid=2001, egid=2001: Operation not permitted Then both users are logged out. Is there another setting I have to change to enable multiple connections per imap/pop3 process in dovecot-2.0, or does it just not work yet? I tried changing client_limit=5 but that had no effect. (I suggest that master.conf needs more documentation.) Thanks.
