Mail undeliverable

[Scott]

This morning when I fired up my computer and started
Outlook, it checked e-mail as it normally does. However,
when I authored several messages and sent them, they
instantly came back. The from line said 'System
Administrator' and the subject was 'undeliverable.' All day
I have been able to receive messages fine. I logged onto my
ISPs (SBC Global) webmail and was able to send from there.
All of the other user on my network using the same
software, connections, and servers were able to
send/receive. So obviously, the problem is something with
Outlook itself. Any ideas?

I am having the same problem. Seems to have coincided with running the
Windows XP updates. Can receive msgs fine, but they wont send. Get a
message that the server doesn't recognize my e-mail address.

Make sure you add Outlook as an exception to your firewall.

How do I do that? I have been having the same problem.
