well, lets explain as short as I can:
I have problems with mail, cant get IN big-ones mailboxes (such as hotmail, etc). So after a lot of reading, I discovered that my BIG problem is rDNS (Reverse DNS).
In my dedicated hosting (OVH), can set a rDNS for my dedicated IP. In this case is "hosting.serverdomain.com".
Ok, in my MX records of other domain in that server, is set "mail.thedomain.com".
Al works great, except that rDNS is not "good", in dnsinspect.com, I get this error:
WARNING: Found mail servers with inconsistent reverse DNS entries. You should fix them if you are using those servers to send email.
Server:mail.theotherdomain.com.
IP: Myip
PTR (Reverse): hosting.serverdomain.com
So, I can get the reverse changed, but, I have several domains in this server, and I cannot choose just one...
Any clue?

Code:
All mail servers should have a reverse DNS (PTR) entry for each IP address (RFC 1912). Missing reverse DNS entries will make many mail servers to reject your e-mails or mark them as SPAM.
All IP's reverse DNS entries should resolve back to IP address (IP → PTR → IP). Many mail servers are configured to reject e-mails from IPs with inconsistent reverse DNS configuration.
So, I can get the reverse changed, but, I have several domains in this server, and I cannot choose just one...
