[Postfix] Dubbele emails na installatie SpamAssassin

[ShadowAS1]

Beste Tweakers,
Op de mailserver van onze vereniging kregen we veel last van spam, daarop hebben wij spamassassin op deze server geinstalleerd.
Nu is hier (waarschijnlijk) iets in de configuratie misgegaan, want sommige mails komen dubbel aan.

Wij hebben een CentOS VPS met Postfix/Dovecot. Alle users en aliases worden beheerd via PostfixAdmin welke alles opslaat in MySQL. Postfix en dovecot gebruiken deze database ook ter authenticatie.

Ter verduidelijking, het probleem speelt sinds de installatie van spamassassin

Voorbeeld van een log entry:

code:

smtp inet n - n - - smtpd -o content_filter=spamassassin

spamassassin unix - n n - - pipe flags=R user=spamd argv=/usr/bin/spamc -e /usr/bin/sendmail -oi -f ${sender} ${recipient}

Iemand enig idee ?
