I have the following in my acls:
#!!# ACL that is used after the DATA command
check_message:
deny sender_domains = aol.com
message = X-Forgery: NOT AOL MAILER
condition = ${if match {${lc:$h_X-Mailer:}} {(?:aol|atlas)}{no}{yes}}
This catches about 7 emails a day.
The sender addresses in the reject log look like they are all spam
(the connected sending host isn't useful, as my MX record point at
my ISP* who do RBL type blocking for me).
I take it that this is blocking some of punster's customers ?
*(Some of) the people running my ISPs mail server share an office with
Phil Hazel, so I consider it to be at least as well run as my own server.
