I have been getting a lot of spam recently and I spent last weekend cleaning my mail relays so I have complete control over my primary and secondary for all my domains. That didn’t solve my problems so today I added the following to my spamassassin rule sets in /etc/spamassassin/local.cf
header LOCAL_MEDIACOMM_MUA X-Mailer =~ /Mediacomm Communicator/
score LOCAL_MEDIACOMM_MUA 0.1
describe LOCAL_MEDIACOMM_MUA Sent from Mediacomm Communicator MUA
header LOCAL_BAT_MUA X-Mailer =~ /The Bat!/
score LOCAL_BAT_MUA 0.1
describe LOCAL_BAT_MUA Sent from The Bat!
uri LOCAL_URI_SPACES_LIVE /spaces\.live\.com/
score LOCAL_URI_SPACES_LIVE 0.1
describe LOCAL_URI_SPACES_LIVE contains link to spaces.live.com
meta LOCAL_SPACES_MEDIACOMM (LOCAL_URI_SPACES_LIVE && LOCAL_MEDIACOMM_MUA)
score LOCAL_SPACES_MEDIACOMM 20
describe LOCAL_SPACES_MEDIACOMM contains link to spaces.live.com and Mediacomm MUA
meta LOCAL_SPACES_BAT (LOCAL_URI_SPACES_LIVE && LOCAL_BAT_MUA)
score LOCAL_SPACES_BAT 20
describe LOCAL_SPACES_BAT contains link to spaces.live.com and BAT
Hopefully that will catch the spam for the moment.
