Um, no.
Lots of servers allow pop-before-smtp. And with the advent of SMTP Auth
(supported by most MTA's and even most MUA's), a huge number of servers
allow relaying from authenticated users. (And judging from my logs,
many clients happily authenticate even when they don't need to.)
Probably most clueful ISPs allow pop-before-smtp or SMTP Auth or both.
It's trivial to set up and it saves a ton of hassles from roaming users
or users with more than one ISP.
