There's no "make them upgrade" about it.

The present installed base of MUA's is predominantly capable of doing 
SMTP AUTH out of the box, and every new PC sold with OE included free 
o' charge (yuk, but that's a different issue) increases the 
percentage of people who have ready access to the tools.

"Roaming" is not a right, its a privilege, and if you're one of the 
minority still using an MUA from 5 years ago that doesn't support it, 
then that's your own lookout.
