MX - DNS - SMTP questions

Hi,

This is my first time setting up an exchange server from home so please bear with..

Basically I've brought a domain "plushdafunk.com" and had my registra (fasthosts) point it to my static IP 81.149.161.172 provided by my ADSL provider (BTopenworld).   I've setup my DNS & MX stuff free on web-dns.co.uk.  

I setup my Exchange 2003 srv and used the wizard to guide me through my Mail SMTP connector...  Sending Email works fine, but I can't receive Email. :(
Opened up port 25 to my Exch srv on my router/firwall - I can Telnet to it from external.

I've check my config on www.checkdns.net  and it tells me that Some of my MX do not work properly -Answer from ns1.nsnoc.com: host 10,mail.plushdafunk.com not found.   (my server name is not called "mail")  

Is there a problem with my MX record hosted on web-dns? is it a problem the SMTP connector on my exchange? is there a problem with my Domian DNS setup? Or is it something to do with BTopenworld ?   Please help..

You need to add an A record for mail.plushdafunk.com to point to the IP address of your router (81.149.161.173.)  It's common for mx records to point to a mail.domain.com address with the mail.domain.com address pointing to your router.

Add that mail.plushdafunk.com record into the ISP's DNS and it will work fine after that.
