This is a typical Sendmail/MTA problem. You have the MX setup right in DNS, so the mail arrives at your server - but you haven't added the DNS name as a valid name for your MTA so your mail server sees the mail but does not think the mail is for local delivery.
For Sendmail you would modify your /etc/mail/sendmail.cw file (or whatever they call it now-a-days). For Postfix you would need to edit /etc/postfix/main.cf (I think...). Anyway, check your MTA documentation or FAQ list. I'm sure this is mentioned prominently there as it is a common mis-configuration (so you're in good company at least).
