Tell them to use the fax machine. Point to point delivery, and fairly reliable 
technology!  ;-P

I spend lots of time telling clueless upperlings the basics of how e-mail 
works. They may be wiz-bang at running multi-million dollar corporations, but 
technology is not their strong point. I tell them that is what they pay me 
for, so they don't have to know everything.

But 5 minutes round trip is extremely good for your volume. Most MUA's don't 
even check that often. My bosses are very happy with 15 minutes, and usually 
only complain if they get timeouts.

But if the complaints will get an increase in your hardware budget, then go 
for it. It won't make it slower.

MailScanner is like deodorant...
You hope everybody uses it, and
you notice quickly if they don't!!!!
