I have like 8 domains hosted in my server. FreeBSD 7.2R=2C sendmail=2C op= enwebmail=2C spamassassin=2C milter all installed. =20 I have few customers complaining that thier emails (the domain they send = from) to hotmail/yahoo..etc.. flagged as spam! i have googled and found most of problems about forward= =2C reverse DNS. for me PTR=2C reverse DNS matchs the domain name. all the 8 domains match= s reverse=2C PTR. =20 if I check that domain in mxtoolbox.com it complains "Warning - Reverse DNS does not match SMTP Banner" could it be the SMTP banner flagging the mail as spam? =20 ofcourse the SMTP banner matchs 1 domain out of the 8. which is my server= main domain. SO if anyone sends any email from my server the SMTP banner will show my = sever name. this one should not be a problem isnt? =20 Now the case become worse! the same customers who are using that domain complaining that even if they send to the same domain name xxx@domain1.co= m to yyy@domain1.com same domain to same server.. its flagged as spam too. =20 No=2C none of my domains in any black list. =20 Anyhints please? =20 Thank you - Marwan Sultan =
