Hello all,

After a recent migration of a mailserver i have some problems with the
training of dspam: when i send a mail for retraining, i have this on logs:

Jun 15 12:50:55 mail2 dspam[27718]: Signature retrieval for
'2,4df84600159243584
817994' failed
Jun 15 12:50:55 mail2 dspam[27718]: Unable to find a valid signature.
Aborting.
Jun 15 12:50:55 mail2 dspam[27718]: process_message returned error -5. 
dropping
 message.

I have checked, the signature is present into the database, but the
query of dspam is wrong (i have activate the mysql debug):

     33 Connect   dspam@localhost on dspam
                   33 Query     SELECT uid FROM dspam_virtual_uids WHERE
username='spam'
                   33 Query     SHOW VARIABLES WHERE
variable_name='max_allowed_packet'
                   33 Query     SHOW VARIABLES WHERE
variable_name='max_allowed_packet'
                   33 Query     SELECT uid FROM dspam_virtual_uids WHERE
username='spam'
                   33 Query     SELECT uid FROM dspam_virtual_uids WHERE
username='spam'

The username is always wrong, is not spam but the username of the sender
e-mail (like clau...@mediaservice.net).

Here is my relevant config on postfix:

in master.cf:

dspam     unix  -       n       n       -       10       pipe
  flags=u user=nobody argv=/usr/sbin/dspam --deliver=innocent
--feature=noise --user ${recipient}
spam    unix    -       n       n       -       -       pipe
  flags=u user=nobody argv=/usr/sbin/dspam --class=spam --source=error
--user spam
nospam  unix    -       n       n       -       -       pipe
  flags=u user=nobody argv=/usr/sbin/dspam --class=innocent
--source=error --user spam

And my dspam.config of mysql:

MySQLServer     /var/run/mysql/mysql.sock
MySQLPort
MySQLUser               dspam
MySQLPass               [pass]
MySQLDb                 dspam
MySQLCompress           true
MySQLVirtualTable          dspam_virtual_uids
MySQLVirtualUIDField       uid
MySQLVirtualUsernameField  username
MySQLUIDInSignature    on


My config is with postfix, dspam and dovecot. My dspam is 3.9.0.

Any help please?

Cheers,

Claudio Prono.
