The heaviest bit of scanning is the spamassassin stuff.

If you create a rule that says don't spam scan on internal emails going out you'll achieve the same thing, but still virus scan etc.

In MailScanner.conf..

Spam Checks = %rules-dir%/spam.rules

In spam.rules, something like..

From:                no
FromOrTo:    default                 yes

Where is the ip-address of the email server...
