All of a sudden I cannont send mail through our main account, we receive
mail just fine. I have another account for work with outlook express
where I switch Identities and log into and that one is just fine, I can
send mail from my second account to my main but cannot send out of my
main. I checked all the mail account properties with the main account and
all is fine, both are through adelphia.net using Outlook Express 6..
Below is the message I get when trying to send out mail in the main
account:

"The message could not be sent because the server rejected the sender's
e-mail address. The sender's e-mail address was 'pmt122@adelphia'. Subject
