Is it:

(a) your server is on the Internet, and your clients are behind the 
dodgy cable modem, or

(b) your mail server behind the dodgy cable modem and the clients are 
out on the Internet

?

Either way I would suggest an improvement to your architecture would be 
to put the mail server on the same side of the dodgy cable modem as the 
majority of users.

If you have a mix of office users and out-of-office users, I would say 
put the mail server on the Internet side. At least then the people 
struggling out in a hotel in the middle of nowhere won't have to fight 
your dodgy cable modem as well as their dodgy foreign internet connection.
