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
