If the SMPT mail server is not recognising me as an authorised user, why can
I send e-mail's to everyone else ? I only have one ISP and my anti-virus is
the same as this morning when I could send e-mails to @homecall.co.uk.

As of today I cannot send e-mails to above domain, I am @ntlworld.com, I
can
send e-mail to anyone else. My friend @homecall.co.uk can send me e-mail
and
other people, When I send e-mail to @homecall.co.uk (I have tried 3
accounts)
it is returned immediately with the following message :
