It's their billing model.  Most ISPs refuse to support secure SMTP
because of the perceived cost of encryption.  The relayer does, but
charges you twice as much for using TLS (actually, mails/bytes are
billed against your account limit at 2x their value).  But that's
unrelated to...

the fixed-address stuff: they sell allowable addresses in blocks of 15,
probably figuring that if you're representing more than 15 mail
addresses, you're really a business and should be paying more.  A real
nuisance for Linux systems where every daemon and his brother sends mail
with a different "From:" address.
