Spam filtering in Exim 3x
rbl_domains = bl.spamcop.net/reject:\
blackholes.wirehub.net/reject:\

list.dsbl.org/reject:\

spam.dnsrbl.net/reject:\
relays.ordb.org/reject:\
dialups.relays.osirusoft.com/reject
+ our own lists of spammers domains and IPs, but we cannot block 100% of spam ;(
My question: is it possible in Exim 3x to refuse connection on SMTP time using list of prohibited/faked HELO strings ( ie (compuserve), (j4hsfhhs), (microsoft) etc) I know it is possible in Exim 4x.
p.s. RBL refuse statistics for 3 servers, starting 2003-03-23 04:00 till now
