Hi SA peeps,

I noticed that I was triggering
"RCVD_IN_PBL,RCVD_IN_SORBS_DUL,RDNS_DYNAMIC" when sending mail through
my own spamassassin, which is spamassassin-3.2.5-2 from the fc10 repo,
configured via mimedefang and sendmail-milter.

I decided to try sending through my ISP's smtp server instead, and it
doesn't trigger the same rules, even though the content is the same, and
the client IP address is the same. I have posted the headers below, I
was hoping that someone could explain what the differences are that
trigger the rules on the first set of headers...?

This triggers;
