I have a VPS running CentOS. This server has a hostname of server.domain.com and an IP of 1.1.1.1.
I have a dedicated IP address on the server of 2.2.2.2 which runs a domain second.com. Second.com, is my main domain. I use this domain to send mail. I am trying to configure this as my main mail domain but I cannot get my SMTP reverse banner to work- it keeps showing server.domin.com
Is it ok to have my server hostname for my reverse smtp banner? On windows, this is something I do not do- I set everything to line up to one A record mail.domain.com.
Does anyone know how to configure Exim to do what I am asking? I of course read http://docs.cpanel.net/twiki/bin/view/AllDocumentation/WHMDocs/EximDifferentIps which did nothing.
