Do you mean that you can't use a different address, or that you can't use a
different SMTP server than theirs. You shouldn't be able to use a different SMTP
server: open relays are easy targets for abuse and spam-mongering. Actually, the
SMTP server you use has no relation to your email address AT ALL. I have 4
different accounts with different providers. I simply use the correct POP server
for each, and change the SMTP server details depending on which provider I'm
connecting through (I have an applescript set up to do this automatically). SMTP
is just a relaying protocol, it doesn't care what you're sending or who you
claim to be, the SMTP relays (like Sendmail) usually just care that your IP
address is part of their domain.
