We use a similar approach. I wouldn't call it "simple". I wouldn't call it "\"intelligent\"". It's simply hard work. We combine asn, hostname, rbl and helo tests, dns adress verifikation and several other sanity checks in the pre data phase. Nevertheless, a lot of spam and malware pass through. Only a (full featured) spamassassin in conjunction with clamAV is able to clean it up. - oliver -- ## 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/
