Every message returned

C

Carolyn Kay

Since yesterday morning, every message I try to send is returned by a
"System Administrator", which I don't know who that could be, since I'm not
on Exchange or anything like that. My ISP swears it's not their fault.
Because I was having problems with Outlook hanging up, I finally bit the
bullet this morning and re-loaded all my software from scratch. It's still
happening.

The error message is 550 relaying to <email address> prohibited by
administrator.

Any ideas?

Right-click on the subject of the message in the Inbox and choose Options or
open the message and click View>Options. That will show the email address
that sent the message.

Sounds like you're not properly authenticating to your outgoing server.
