[Dovecot] Install Configuring and run.

Fri Nov 14 12:40:13 EET 2008

Hello Thorsten , Hello All in List,

i got to write again,
ok : dspam workinng , dovecot-antispam working

moving mails to or out of spam seems to work and is listed in the logs;
BUT the logs shows this on moving a mail to or from spam =

Nov 14 11:31:57 kraftwerk1 imap: antispam: /usr/bin/dspam --source=error 
--class=innocent 
--signature==?iso-8859-1?Q?1,491d521770551288576733=0D?= ...
Nov 14 11:31:57 kraftwerk1 dspam[7203]: _ds_get_signature(): 
_mysql_drv_getpwuid(0) failed: aborting
Nov 14 11:31:57 kraftwerk1 dspam[7203]: Signature retrieval for 
'=?iso-8859-1?Q?1,491d521770551288576733=0D?=' failed
Nov 14 11:31:57 kraftwerk1 dspam[7203]: Unable to find a valid 
signature. Aborting.
Nov 14 11:31:57 kraftwerk1 dspam[7203]: process_message returned error 
-5.  dropping message.

incoming mails are scanned by user clamav and mails are moved now by 
user clamav after the the Tip of  Thorsten adding this to dovecot.conf =

antispam_dspam_args = --user;clamav

the following point in the logs  "mysql_drv_getpwuid(0)"  , looks for me 
like dspam tries with User-ID 0 to work,
but User clamav is in the mysql-db with User ID 1

do i have to set any special entires in dovecot.conf or dspam.conf ?
