Greetings! I hope you can help me - I'm a steam age man and baffled by electronics.
Just back from holiday, during which computer has been shut down.
I've changed nothing - not been fiddling with things I don't understand!
I can receive emails on my Windows Live Mail Account, but when I try to send emails I get this message -
The message could not be sent because the server rejected the sender's email address.
xxxxxxxxxxxx@ntlworld.com
Subject 'Re: Meeting 5th December'
Server Error: 555
Server Response: 555 Invalid email address.
Server: 'smtp.ntlworld.com'
Windows Live Mail Error ID: 0x800CCC78
Protocol: SMTP
Port: 25
Secure(SSL): No
Strangely enough I can send emails on the same account, using the same modem / router thingy, on my smart phone.
What do I need to do, or who do I need to contact?
Any help gratefully received,
Thanks in advance,
Simon
