We are running our own mail server (postfix/dovecot) and we are severely hit by spam lately. The spam is
especially directed to one particular email address.
We have installed spamassassin and let the score to be the default (5). However, most of the spam
messages's score is calculated much below 5, and thus spamassasin is not tagging them as spam.
X-Spam-Status: No, score=1.9 required=5.0 tests=HTML_MESSAGE,RP_MATCHES_RCVD,
We also installed amavisd, agents like pyzor, razor and installed dcc too. Inspite of this, we
still get lot of spam which is not detected as spam by spamassassin. Is spamassassin miscalculating?
What else can I do to stop the spam?
