Trouble Sending E-mails

[calisurfchick518]

My sending and receiving works great when I'm at school, but if I bring my
computer home, sending e-mails will not work-- I get a '550 Relaying Denied'
error. I do not know how to fix this so that it will work both places.

Your outgoing mail address contains domain A and you're trying to send your
message using domain B. Most ISPs won't allow you to send mail through their
domain unless your address is in their domain. Usually, if you authenticate
properly to the outgoing server, though, you can send with no problem.
