Not true.  If I want to send mail to foo at example.com, all I have to do
is look up the MX record for example.com and talk to port 25 on that
machine.  No local (or ISP-level) mail server is necessary.

Things like SPF might complicate this if you want to send mail with a
>From field of me at yourcompany.com, so I wouldn't necessarily recommend
it.  Then again, I sent this message with that technique, so it
apparently works.
