On behalf of d4x and myself, thanks for the additional info...

 Fair point there... However, asking for your kind tolerance, 
I have decided to forward his e-mail address directly to you 
via PM - for the record, I have no issues whatsoever receiving 
mails from that address/TalkTalk SMTP server (and they are not 
marked as spam, either by my mailer nor Security suite);  
likewise, my replies to that address reach d4x successfully...

Thank you for your patience and support.

Kind regards, 
Vangelis.
