I am so frustrated, my server's ip is still listed on some of the blacklist sites. I have all servers on one machine, one ip (web, dns, email etc) Server host name is server1.mycompany.com I have configed the reverse DNS to be server1.mycompany.com as well I host about 10 sites on my server, let's see www.com1.com, www.com2.com etc. I want to have he following emails, such as [email protected], [email protected] etc. and these sites are owned by me, so there is no spams from these emails. So is there any tutorials on how to get these working so these blacklist sites won't list me? One thing I am not sure is the smtp server name. Since I only have one ip/physical server, and the rDNS is point to my main server, which is server1.mycompany.com. So when I send email from [email protected], should I use server1.mycompany.com as SMTP? or mail.com1.com? (they both point to the same ip)... but if I use server1.tiaocorp.com, then the email domain is different than the smtp domain, but if i use mail.com1.com as smpt server, then the rDNS won't match... so how does it work? Please help thanks!
