watermarking to bypass content scanning?

[Kit Wong]

Hi Martin

Thanks for that. I already have it setup to not scan any "server
generate emails" and any whitelisted ip addresses.
I have 90% of users use the server to relay emails. Their ip addresses
are whitelisted, which by pass any scanning. Its just the emails that
users receive that are scanned along with reply emails.

EG. User from my server a at myserver.com sends to another server
b at anotheruser.com then b at anotheruser.com 's reply should bypass
mailscanner also.

I just find it unnecessary especially of the original email have a
watermark in.

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:        10.1.1.26                no
FromOrTo:    default                 yes

Where 10.1.1.26 is the ip-address of the email server...
