Hello All,
I have a few questions on the above.
Once upon a time Dave C posted some ACL statements that he was using to "try"
and stop forgeries of the $subject addresses.
http://www.exim.org/mailman/htdig/exim-users/Week-of-Mon-20020610/039790.html
It would appear that some of those ACLs have been overtaken by events when
it comes to ASMTP. I doubt whether hotmail does asmtp, but who know? They
may as well..
One of those acls was:
# All yahoo.com mail will have either
# "...yahoo.com via HTTP "
# *OR*
# "...yahoo.com with NNFMP"
deny sender_domains = yahoo.com
message = X-Forgery: NOT YAHOO SERVER
condition = ${if match {$h_Received:}{yahoo.com.via.HTTP}{no}{yes}}
condition = ${if match {$h_Received:}{yahoo.com.with.NNFMP}{no}{yes}}
I have used that and it seemed to work fine until a few days ago when suddenly
a client complained. The complaint is below. Real Address details are masked out
from spammers eyes.
It seems that yahoo is allowing ASMTP connections. In order not to allow stupid
open relaying, how would I write a condition to match the $h_Received: show below??

Good leaders being scarce, following yourself is allowed.
