spamass + spf

i installed the spf module. does anyone know if SA will now globally add a penalty for spf fails? is there anything i would configure in iMS (e.g. spamassassin.opt, etc.)? any idea on where this is adjusted (e.g. how much to penalize, etc.)?

As long as you have already configured Messaging for SA, there shouldn't be anthing further there.You can use "spamassassin --lint --debug" to see if SPF is activated. You might want to join and ask in the spamassassin mail group for how to set penalites. I honestly don't know.

Hi,

I wouldn't recommend using SPF with SpamAssassin and messaging server. For SPF to work correctly SpamAssassin needs to know what the original "Mail From:" address (e.g. through a Return-Path: header) and also the IP of the source host (through Received: header information).

I was unable to get the Return-Path: to be reliably added to incoming emails, so emails with multiple Return-Path: headers weren't handled correctly by SpamAssassin.

Also forwarding of emails tends to break SPF, causing false-positives.

Your results may vary but I would recommend keeping an eye out for false-positive SPF matches.

Regards,

Shane.
