Mail Server Issue

[starfish]

Hi,

I've been setting up snow leopard server to host my website, ical, address book and email. The server has a static public IP and the domain is setup with 123 reg as the following:

A Record: @ - public static IP (e.g. 80.11.46.55)
A Record: mail - public static IP
A Record: www - public static IP

MX Record: mail.domainname.com. (incl. full stop) - Priority 10


The website works no problem, the server page is accessible at http://www.domainname.com:85 and E-mails can send out from the server but they are only received when sent in the following format:

mailbox@servername.domainname.com

I want it to receive as mailbox@domainname.com

I'm guessing this is an DNS/MX record issue but I'm stuck! Not sure if the problem lies at the 123 reg stage or on the server.

I have forwarded the ports for Web, IMAP, POP and SMTP on my router to the server's internal IP (192.168.1.50)

Can anyone offer assistance please?

Thanks in advance,

Mike

you need MX records in addition to A records:
domain.com. IN MX 5 mail.domain.com.
domain.com. IN MX 10 mail2.domain.com.

You can test by substituting your domain for macrumors.com

$ dig -t MX macrumors.com

; <<>> DiG 9.6.0-APPLE-P2 <<>> -t MX macrumors.com
