Outlook Express : Relaying denied.

Since i switched from isdn to adsl i get the following error when trying to send a mail:

Relaying denied. Proper authentication required.', Port: 25, Secure(SSL): Yes, Server Error: 550, Error Number: 0x800CCC79

Even when i turn on smtp authentication i still get this error.

When i switch back to dial in connection i don't get the error message.

Is something different with the way adsl handles authentication??
What causes this problem?

Any help would be very appreciated

Hi mkraan,

Is there any firewall program associated with your adsl connection ? If yes or no, try to turn off any firewall and
anti-virus temporarily and see if that would help

After checking "outgoing mail server requires authentication", click on "settings"
and give the username and password there and also check the option of connecting securely in there.
See if that would help .

Have you ever been able to send email in OE using adsl. If yes , then delete the email account, create it again and see if that would help

Post back how it goes

Hi sunray,

After turning of firewall and anti virus, is still receive the error..
I also tried entering username and password and Secure Password Authentication..

I have 2 e-mail accounts : one is from myl old internet provider, the other is from my work.
With both i cannot send e-mail now, and return the same error messages.

This also happens when i try to send the mail using the same account on another pc, on cable adsl..

using adsl connection , can you go command prompt and ping the outgoing mail server..
