When I post using my e-mail address I get
The e-mail address entered appears to be invalid. There may be problems with the domain name or with the user mailbox.
I posted this using a long dead e-mail address and get no error
just to see, I did a send/receive in outlook and the server is alive

PS Jon: maybe it would be an idea to add "forum' as a 'MCU' in the above field
