Sounds like relaying issue. Is the email account correctly setup for the ISP
you're connected to? Or are you trying to send mail thru ISP-B SMTP mail
server while connected to ISP-A network?

When i try to send emails from one of my accounts(i have two) I get an
error
message saying "553 sorry that domain isn't in my list of allowed
rcpthosts"

encounterd this problem and corrected it.
Thank you,
