Plesk and SpamAssassain

[MFromH]

Hi Forum,

my server works with SuseLinux 10.0, Plesk 8.4 and SpamAssassin 3.1.3. I know, that these are not the latest versions, but I'm totally new to this server and I don't dare to update yet.

We receive a lot of spam like "Your Order", "Your E-Mail-Account has been cancelled", "Delivery Status Notification (Failure)", "RE: Message". E-Mail-Headers look like this:

DomainKey-Status: no signature
X-Spam-Checker-Version: SpamAssassin 3.1.3 (2006-06-01) on

X-Spam-Level:

Here is /etc/mail/spamassassin/local.cf
rewrite_header subject *****SPAM*****
required_score 7
whitelist_from xxxx@xxxx.xx

Is it possible, to change these settings using Plesk?
Will any changes on local.cf influence the systemwide behavior of SpamAssassin?
How can a score become negative (see example above)?

Thanks in advance for your support.

Hello Michael,

Spam assassin score settings can be configured on 2 levels:
On server-wide: Plesk CP > Spam Filter
/etc/mail/spamassassin/local.cf is changed in accordance.

and particularly for every mailbox (these settings take precedence):
Plesk CP > Domains > Mail > mailbox > Spam filter.

Spam filter settings made is Plesk CP are spread in SpamAssassin configuration on the server.

Yes and no. You can configure blacklist and whitelist and how Q-Mail deals with Spam-Levels. But you can't configure the waste amount of parameters, that determine spamassassins behaviour during E-Mail-check. In particular, you can't configure network options like skip_rbl_checks, use_razor2, use_dcc, use_pyzor.

Our spamassassin was a "toothless tiger", until I configured these settings manually.
