Mostly for porn, AFAIK.
I've not seen a uuencoded file in e-mail for years.
Dumping undelimited uuencode "attachments" into a plain E-mail text body
is quite common in automated notifications from commercial applications.
The heuristic is indeed to look for a correct formatted "begin" line,
and the decode what follows as long as it's correct format. Ugly indeed,
but nearly every E-mail client I'm aware of still supports it. (And, as
noted earlier, Gmail does now, too.)
