It shouldn't have any relation, but it does. When I tried to send mail 
out using From: and Reply-to: headers that use the domains of my 
websites, the mail simply went into the bit bucket, with no indication
to me that my mail was being refused.

An SMTP server shouldn't accept mail from strangers, but there is
no reason why an AOL user shouldn't be able to buy SMTP services
from their webhosting company; after all, AOL doesn't provide an 
SMTP server.  Typically, the hosts are set up so that you have to
check your POP3 box with a valid username and password immediately
before you send mail.

And open relays are no more of a problem than web hosting companies.
Sign up for an account that includes sendmail, and you can spam an
awful lot before you get caught.
