Spamassassin Whitelist
 

I am wanting to enable a whitelist for Spamassassin. Basically I feel it is a waste of time for SPAM to score any emails coming from my own domain. If my email server is carlwill.com, I would like any emails coming from a *@carlwill.com to be whitelisted for Spamassassin. Is this possible and if so, has anyone done so and tell me where to add the white list and how to enable it?

According to this, it's not too hard to do. I'd advise being careful in the example you gave though. I often get spam (used to, spamassassin does a good job) whose from address is in one of my domains. It seems pretty common for the from address to be the same as the to address with spam.

At this stage, SPF usage doesn't seem to be common so I just rely on spamassassin identifying the contents.
