I'm wanting zimbra to receive and send email via my website domain using POP3 and SMTP.
I have named my zimbra server zmail.mydomain.com. You can access my website at mydomain.com also. I used the...

when i use SplitDNS do i have to change my MX and A records to my zimbra sever in my domain thats hosted on Site5.

I want to Zimbra to only receive and send email using our existing domain POP and SMTP servers (eg: mail.domain.com for both servers). This is my 3rd install of Zimbra just trying all of it out. *LOL...
