But the sender host address will typically be some open relay or zombie which has so far escaped the DNSrbls. The idea is to catch them by recognising (via the MX and A records) that the MTA which services their envelope sender domain has an IP which is within a range controlled by spammers. This will be in general a completely different IP than the IP which is offering us the mail. best regards -- ## List details at http://www.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://www.exim.org/eximwiki/
