DNS problems (PM me the the domain name if you don't want to post it here)Can send and recieve internal ones

Firewall problems?
Software configuration changes, Antivirus updates etc? (unlikely but worth checking)
Check the smtp logs for your mail server to see if anything is actually connecting to it from the outside world.
Those are starting points.
anti-spam?
A bit more info. might help.
I'd guess you've got an Exchange Server / Postmaster somewhere, but before this there should be at least 2-3 levels of security..
i.e.
Gateway/Surf Control
Anti-Virus
Spam/Anti Spam
You need to check each stage... As email will drop out at each one of these..
Is it only you or all of your users who are unable to receive email?
Does the email travel on the same connection as your internet? (Which I'm guessing you're using to post this?) It might be that an external or possibly internal connection is down or not behaving as expected..
