Can they send *large* email's?

I have seen this sort of thing through firewalls where the MTU was
unreasonable and the firewall refused to allow packet fragmentation

There is an option to the unix versions of traceroute to test with large
packets, they could try that

The only other thing ian thnk of is you have a port 80 filter somewhere
If they coonnect to the server via say, telnet IP 80 , what do they get?
does it refuse to cinnect? or connect and hang?
