551 delivery not allowed "HELP ME"

I can send and receive emails from home with no problems, but when I reply to an email I always get this error as soon as I click send and receive:

Subject: Undeliverable

Any Ideas?

I have exactly the same problem, can anyone advise?

I've searched the MS Knowledge base and couldn't find any help there. Checked Google, found a link to a site that I couldn't load (will try again later)

I can send an email from myself to my self ok but as stated in the begining of this thread, I'm totally unable to send emails to anyone else.

I also recently had another problem with Outlook, this was profile related and I deleted all the profiles and created a new one, tested the settings and POP3/SMTP connected and sent and received ok?

Any ideas?

Cheers

We need to see the whole header of the message -- i.e. whether the error is coming from your mail server or the recipient's e-mail server.

In Outlook, right-click the message and hit Options. The headers will be in a greyed out window at the bottom. Copy and paste that here (after altering usernames and IP addresses, of course).

Off the top if my head, it looks like you're trying to send e-mail to "Joe Blogg" instead of joe.blogg@yahoo.com or something like that. Obviously this won't work -- e-mail has to have a fully qualified address (not including Exchange and stuff).

Are you certain you are using the correct SMTP server for the ISP you are using and if so are being authenticated on it if needed? Either that or the port is being blocked on the firewall but I would tend to lean more on the SMTP server setting being the issue.

Some ISPs using webmail do not allow mail forwarding other than to their own subscribers
