missing space before "REJECT".
but why do you use header_checks for this? check_client_access is better.
...
check_client_access cidr:/etc/postfix/access_client.cidr
== access_client.cidr:
24.155.144.16/28 REJECT spammy network (Targetmail)
24.155.144.32/28 REJECT spammy network (Targetmail)
and/or
...
check_client_access hash:/etc/postfix/access_client
== access_client:
mycouponsavingsmail.com REJECT spammy network (Targetmail)
.mycouponsavingsmail.com REJECT spammy network (Targetmail)
but you'll have a lot of work to track the domain names. See if uribl is
good for you...
