Hello, dovecot-1.0.3 on Fedora 6 works perfect in general but sometimes the system becomes unresponsive and the log file shows tons of messages like this: ... imap-login: Disconnected: Shutting down: 127.0.0.1, secured ... pop3-login: Disconnected: Shutting down: aa.bb.cc.dd Restarting dovecot helps, but what's behind?

[Dovecot] dovecot sieve notify example?
by Thanh Han The 11 Sep '07

11 Sep '07

Dear list, I was trying to use the "notify" action with dovecot sieve but I just couldn't get it work. The relevant lines look as follows: ,-------- |require ["fileinto", "notyfy"]; | if header :contains ["to", "cc"] ["userA(a)example.com", "userB(a)example.com"] { | notify | :method "mailto" | :options "userC(a)example.com" | :low | :message "notification"; | keep; | stop; | } `-------- But I get in log file the error ,-------- | Sep 11 10:51:25 host30 deliver(abc(a)example.com): sieve runtime error: Notify: Generic Error `-------- Can someone please give me a hint what I did wrong, or give an example how a sieve notify action should look like? I appended my configuration below, in case it matters. I am running linux debian etch, and use the postfix/dovecot packages from debian repository. Thanks for your consideration, Thanh Output from 'dovecot -n': ,-------- | ssl_listen: *:993 | ssl_ca_file: /etc/ssl/certs/cacert.pem | ssl_cert_file: /etc/ssl/certs/cert.pem | ssl_key_file: /etc/ssl/private/key.pem | disable_plaintext_auth: no | login_dir: /var/run/dovecot/login | login_executable: /usr/lib/dovecot/imap-login | mail_extra_groups: mail | mail_location: maildir:/var/mail/vmail/%n | auth default: | user: nobody | passdb: | driver: ldap | args: /etc/dovecot/dovecot-ldap.conf | userdb: | driver: static | args: uid=520 gid=520 home=/var/mail/vmail/%n allow_all_users=yes | socket: | type: listen | client: | path: /var/spool/postfix/private/auth | mode: 432 | user: postfix | group: postfix | master: | path: /var/run/dovecot/auth-master | mode: 384 | user: vmail `-------- dovecot-ldap.conf: ,-------- | hosts = 192.168.100.20:389 | ldap_version = 3 | base = ou=People,dc=example,dc=com | deref = never | scope = onelevel | auth_bind = yes | auth_bind_userdn = uid=%n,ou=People,dc=example,dc=com `--------

[Dovecot] Deliver parameter problem
by Umut Arus 11 Sep '07

11 Sep '07

Hello, I'm using dovecot-1.0.5 with postfix. I have to use deliver from procmail because I have some filters. There is no document about how to using deliver parameters (-d) other than http://wiki.dovecot.org/LDA . If I set -d parameters manually as a username everything is ok. I can not set users' mail quota (don't lookup) with mysql db if I haven't set -d parameter as receipt username in procmail. How can I describe user (-d) parameter's variable in procmail? Procmail configuration, :0 | /usr/local/dovecot/libexec/dovecot/deliver -f $blabla -d $blabla2 Output of the configuration, # 1.0.5: /usr/local/dovecot/etc/dovecot.conf protocols: imap imaps pop3 pop3s listen: 10.1.1.168 ssl_cert_file: /usr/local/dovecot/etc/dovecot.cert.pem ssl_key_file: /usr/local/dovecot/etc/dovecot.key.pem disable_plaintext_auth: no login_dir: /usr/local/dovecot/var/run/dovecot/login login_executable(default): /usr/local/dovecot/libexec/dovecot/imap-login login_executable(imap): /usr/local/dovecot/libexec/dovecot/imap-login login_executable(pop3): /usr/local/dovecot/libexec/dovecot/pop3-login mail_location: maildir:%h/Maildir:INDEX=/var/no-quotas/index/%u:CONTROL=/var/no-quotas/control/%u mail_debug: yes mail_full_filesystem_access: yes mail_executable(default): /usr/local/dovecot/libexec/dovecot/imap mail_executable(imap): /usr/local/dovecot/libexec/dovecot/imap mail_executable(pop3): /usr/local/dovecot/libexec/dovecot/pop3 mail_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(pop3): mail_plugin_dir(default): /usr/local/dovecot/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/dovecot/lib/dovecot/imap mail_plugin_dir(pop3): /usr/local/dovecot/lib/dovecot/pop3 pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %08Xv%08Xu namespace: type: private separator: / location: maildir:~/Maildir:INDEX=/var/no-quotas/index/%u:CONTROL=/var/no-quotas/control/%u inbox: yes namespace: type: private separator: / prefix: mail/ location: maildir:~/Maildir/.mail:INDEX=/var/no-quotas/index/%u:CONTROL=/var/no-quotas/control/%u auth default: verbose: yes debug: yes passdb: driver: pam userdb: driver: sql args: /usr/local/dovecot/etc/dovecot-sql.conf userdb: driver: prefetch socket: type: listen master: path: /var/run/dovecot/auth-master mode: 438 plugin: quota: maildir:storage=500000:ignore=trash regards,

Hi all Does the list work? I have sent two mail without answer up today. I want to change Courrier-imap by dovecot but i have problems with quota and sieve in dovecot. would you help validating dovecot? I this does not work i would have to stay with courier-imap.

[Dovecot] postfix + dspam + dovecot problem
by Lars Stavholm 11 Sep '07

11 Sep '07

Hi All, I'm new to dovecot (coming from cyrus) and have a bit of a problem setting up postfix + dspam + dovecot. 1. postfix + dovecot: works like a charm. Using "mailbox_command = /usr/lib/dovecot/deliver" in postfix main.cf 2. adding dspam to the equation: unable to deliver: net_connect(/usr/var/run/dovecot/auth-master) failed: No such file or directory Using "mailbox_transport = lmtp:unix:/var/tmp/dspam.sock" in postfix main.cf (instead of the above mailbox_command), and the corresponding setting in master.cf. In /etc/dspam.conf I'm using... TrustedDeliveryAgent "/usr/lib/dovecot/deliver" And here's the full error message: Sep 11 02:10:38 nwinnie postfix/pickup[18313]: 090F1C042: uid=0 from=<root> Sep 11 02:10:38 nwinnie postfix/cleanup[7010]: 090F1C042: message-id=<20070911001038.090F1C042(a)nwinnie.telcotec.se> Sep 11 02:10:38 nwinnie postfix/qmgr[18318]: 090F1C042: from=<root(a)nwinnie.telcotec.se>, size=431, nrcpt=1 (queue active) Sep 11 02:10:38 nwinnie deliver(stava(a)nwinnie.telcotec.se): net_connect(/usr/var/run/dovecot/auth-master) failed: No such file or directory Sep 11 02:10:38 nwinnie dspam[10379]: Delivery agent returned exit code 75: /usr/lib/dovecot/deliver -d stava(a)nwinnie.telcotec.se Sep 11 02:10:38 nwinnie postfix/lmtp[7018]: 090F1C042: to=<stava(a)nwinnie.telcotec.se>, orig_to=<stava>, relay=nwinnie.telcotec.se[/var/tmp/dspam.sock], delay=0.35, delays=0.32/0.01/0.01/0.01, dsn=4.3.0, status=deferred (host nwinnie.telcotec.se[/var/tmp/dspam.sock] said: 421 4.3.0 <stava(a)nwinnie.telcotec.se> Delivered (in reply to end of DATA command)) So, postfix hands the message to dspam, dspam does its thing, dspam tries to deliver and fails. What throws me is that the delivery works as expected in case 1) but not in case 2), despite the fact I'm using the same delivery agent, i.e. /usr/lib/dovecot/deliver. Why would dovecot go for some other authentication method in case 2)? BTW, we're using PAM on top of LDAP. Any ideas appreciated. Cheers /Lars

[Dovecot] Write-only mailboxes
by Steffen Kaiser 11 Sep '07

11 Sep '07

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, I've setup a mailbox for reporting SPAM by simply symlinking it into the Maildir of selected users. In order to preserve anonymity of the users I setup the mailbox as follows: drwxr-xr-t 5 root fb 4096 2007-09-05 16:18 ./ drwxr-xr-x 7 root root 4096 2007-09-05 16:16 ../ drwx-wx-wt 2 spamd fb 12288 2007-09-10 16:17 cur/ hence, with read permission for the spam bot only. When Thunderbird copies mails from the same mail account into the folder, it seems like it tries to select the mail box afterwards, then a "Internal error occured. Refer to server log for more information." because of permission denied. When one copies mail from yet another account into the SPAM box, no such message appears. I guess, Thunderbird does not try the refresh the message count. Well, is there a possiblity to setup a Write-Only mailbox, with Dovecot v1.0.3 with the ACL plugin? Is there a working setup for write-only mailboxes with the ACL plugin?
