Hi,

I installed a Emailserver based on Debian Sarge, exim (4.50-8sarge2) and dovecot (1.0.rc2-1bpo1). Delivering Mails with Exim to my Maildir works fine. Because I want to filter my messages with Sieve, I tried to deliver mails with deliver, but get the following error message (example with a testmail and user "Debian-exim", not delivered via Exim):

--8<-- dovecot: 2006-09-19 13:17:23 Error: auth(default): deliver(username@domain.tld): "2006-09-19 13:17:23 "Fatal: setgid(1003) failed: Operation not permitted --8<--

Here's the relevant part of my configuration file:

--8<-- auth default { mechanisms = plain login passdb sql { args = /etc/dovecot/dovecot-sql.conf } userdb sql { args = /etc/dovecot/dovecot-sql.conf } socket listen { master { path = /var/run/dovecot/auth-master mode = 0660 user = virtual group = virtual } } } --8<--

User "Debian-exim" is in the same group as user "virtual". Both have r/w-permissions on /var/run/dovecot/auth-master:

0 srw-rw---- 1 virtual virtual 0 2006-09-18 13:58 /var/run/dovecot/auth-master

Is there anybody who had the same problems and can help me?

Best regards,

Michael.

PS: Sorry for my horrible english.
