Need some info on the what the large email severs ie Yahoo and Hotmail use to determine if email is spam. I run a small email server with about 30 clients and when i send email to yahoo it gets bounced to the bulk mail folder like in my maillog below. Jul 5 15:30:19 v22 postfix/smtp[14316]: starting TLS engine Jul 5 15:30:19 v22 postfix/smtp[14316]: C52C23C9: to=<vanginnekenr@yahoo.com>, relay=mx2.mail.yahoo.com[64.156.215.8], delay=1, status=sent (250 ok dirdel) Read somewhere that they do a reverse lookup on your ip address for a host name. here is my info for reverse lookup for the ip 209.115.173.22 Non-authoritative answer: 22.173.115.209.in-addr.arpa name = mail1.computerking.ca. Authoritative answers can be found from: 173.115.209.in-addr.arpa nameserver = toad.spots.ab.ca. 173.115.209.in-addr.arpa nameserver = cheetah.spots.ab.ca. toad.spots.ab.ca internet address = 209.115.174.3 cheetah.spots.ab.ca internet address = 209.115.174.2 looking forward for computerking.ca Server: ns1.kloth.net Address: 213.133.98.149#53 Non-authoritative answer: Name: computerking.ca Address: 209.115.173.22 computerking.ca mail exchanger = 10 mail1.computerking.ca. computerking.ca mail exchanger = 20 mail1.shoemasters.computerking.ca. computerking.ca mail exchanger = 30 mail1.highcoup.ca. computerking.ca origin = computerking.ca. mail addr = root.computerking.ca. serial = 2004062001 refresh = 10800 retry = 3600 expire = 604800 minimum = 3600 computerking.ca nameserver = ns1.shoemasters.computerking.ca. computerking.ca nameserver = ns1.computerking.ca. computerking.ca nameserver = ns1.highcoup.ca. Authoritative answers can be found from: computerking.ca nameserver = ns1.highcoup.ca. computerking.ca nameserver = ns1.shoemasters.computerking.ca. computerking.ca nameserver = ns1.computerking.ca. mail1.computerking.ca internet address = 209.115.173.22 mail1.shoemasters.computerking.ca internet address = 68.144.231.38 Does it have something to do with the fact that my ISP is running the NS for reverse lookup and my own nameservers take care of things for forward lookups. Should i see if i can run my own nameservers for reverse lookup as well. What is it that yahoo does not like about my setup. please someone help me i do not know what could be wrong and have switched ISP's to try and solve this problem but so far it has not worked.
