You could replace the imap or pop3 helper program with a wrapper that first sends the fetchmail daemon a wakeup signal, waits a few secs and then calls the original.

Does someone know, if in the new release of dovecot 2.x.x there is a feature implemented, that wakes fetchmail or any other program on a client request, or is the "fetchmail wakeup" plugin still the only way to do this (at least I've not found any other, and that plugin never worked for me),..

[Dovecot] Combining ManageSieve with hand-written scripts
by Jason Bleazard 30 Aug '10

30 Aug '10

Hi, new to Dovecot, forgive me if I'm missing something basic... I'm trying to figure out if there's a way to use a couple of custom rules alongside ManageSieve. Most of the time I like the ManageSieve interface in Roundcube, but there's one rule that I can't get it to do the way I want (it's a notify rule, and I don't like the way Roundcube constructs the notify). I figured out how to write it by hand, but of course I can't put my own rules in Roundcube's file or it gets really confused. I tried adding an include to the generated file, but Roundcube politely removes it for me the next time I use the rule editor. (Squirrelmail doesn't seem to be any better in this regard.) I thought I could do something like sieve_before = ~/sieve/custom.sieve but that doesn't seem to work. I couldn't even see any evidence in the log that it attempted to look at that file. Apparently sieve_before isn't meant to work on a per-user basis. If I do a global sieve_before, can I have it "include :personal"? If so, what's going to happen with the script compilation? From what I understand, it can't be compiled globally, since each user has a different custom rule set. Am I trying to do the impossible here? Thanks for any ideas, Jason Bleazard

[Dovecot] Different IPs should use different ssl-certs/keys
by Peer Heinlein 30 Aug '10

30 Aug '10

I don't understand how to use multiple keys/certs on different IPs without SNI. http://wiki2.dovecot.org/SSL/DovecotConfiguration explains how to use different keys for different protocols like POP3 and IMAP. But how to bind those keys/ on IPs/Ports? Looks like it is not possible to use ssl_cert inside service { inet_listener {} } Is it still necessary to run multiple instances like it was in Dovecot 1.2.x?

Hi! Is it possible to configure Dovecot so that it drops privileges for dict process? Currently this process is running as root. (At least on my system with Dovecot 1.2.) Best regards Mike

Re: [Dovecot] doveadm expunge -A mailbox Trash savedbefore 30d
by Jerrale G 30 Aug '10

Could you explain the iterate_query in any kind of sql. I'm guessing to just use the query, correctly, that's failing as iterate_query= and put it in the service auth file which includes password_query and user_query. then, I'm guessing to add something like: iteratedb { driver = sql args = /path/to/sql.conf } The wiki2 only says: "When the SQL userdb module is used make sure that the iterate_query setting in /etc/dovecot/dovecot-sql.conf.ext matches your database layout." it should give an example query. I don't know if its wanting to list the fields or the contents of a field. Thanks, Jerrale G Jerrale G. SC Senior Admin

[Dovecot] Can't get dovecot to see email folders
by Blaster 30 Aug '10

30 Aug '10

So I'm very frustrated, I've spent the better part of a day trying to get dovecot 2.0.1 working...Most of the documentation on the Wiki seems to think you are running an older version and therefore very little of it applies. I'm running 2.0.1 on OpenSolaris. I seem to have 2 remaining issues: 1) Dovecot is not able to determine the home directory 2) IMAP clients can not get to the mail folder directory. One client is reporting that it can't open it in read only mode. 3) I tried to get raw logging working, but apparently I couldn't because of #1. The architecture of Dovecot makes it difficult to transition from another IMAP server. If I force the MBOX to be /home/%u/mail, all of my clients think the folders are in /home/%u/mail/mail. If I set mbox location to /home/%u, then dovecot tries to create .subscription and .imap files/directories in the users home dir which it doesn't have permission to do. It would be nice if you could configure Dovecot in such a way as to make transition easier, such as the ability to strip off a duplicate trailing path, ie /home/%u/mail/mail becomes /home/%u/mail....Otherwise this necessitates visiting countless IMAP clients for reconfiguration... Here is my config file: /opt/sbin/dovecot -n # 2.0.1: /opt/etc/dovecot/dovecot.conf # OS: SunOS 5.11 i86pc base_dir = /var/run/dovecot/ mail_debug = yes mail_gid = mail mail_location = mbox:/home/%u/mail:INBOX=/var/mail/%u mail_privileged_group = mail mail_uid = dovecot passdb { driver = pam } plugin { home = /home/%u } service imap-login { inet_listener imap { port = 143 } inet_listener imaps { address = * port = 993 } } service pop3-login { inet_listener pop3 { address = * port = 0 } inet_listener pop3s { address = * port = 0 } } ssl_cert = </usr/local/ssl/certs/dovecot.pem ssl_key = </usr/local/ssl/private/dovecot.pem gremlin [/opt/bin] # gremlin [/opt/bin] #

[Dovecot] PAM authentication fails
by Egbert Jan van den Bussche 29 Aug '10

29 Aug '10

Hi, I'm fighting all weekend on with auth and pam to authenticate local system users. testuser is such local user and is in passwd and shadow. I want to have local system users (testuser is one of them) and virtual users. The virtual part works fine but I cannot get the local user to connect. Still pam fails finding the user. The suggested password mismatch at the end is, in my eyes, because there is no user in the first place. I verified the password by interactive login to the account. The pam module (dovecot) is just the default file with three @includes in it.
