Outgoing scanning

[Denis Beauchemin]

Jonas,

I use "High SpamAssassin Score = 75" on my outgoing servers, while it is at 12 on my incoming servers. You are right about high-scoring spam not being bounced. This takes care of it.

As for having both incoming/outgoing on the same server I had problems with multiple MS instances in separate directories. Too complex to set up and support.

Denis

Hmm I did consider setting up a dedicated outgoing scanning pair, but couldn't really see why I should have any problems distinguishing between incoming and outgoing. Can you elaborate on what problems you ran into?

Also are you sure your high scoring spam is bounce in your setup? As far as I can see mailscanner only allows you to bounce spam, not high scoring spam.

Although I guess if the setup is dedicated for outgoing, you can just mark all spam as normal spam, and none as high scoring..
