My apologies to other members of the list for having to read this,  
however the nature of the problem is such that I cannot reply to  
Roberto privately.

Specifically, my message to Roberto was rejected thus:
--------

This Message was undeliverable due to the following reason:

Your message was not delivered because the return address was refused.

The return address was "<nick@gammon.com.au>"

Please reply to <Postmaster@mx.bigpond.com>
if you feel this message to be in error.

The only guess I can make here is that the return address <nick@gammon.com.au 
> is not in the same domain as the SMTP server <mail- 
hub.bigpond.net.au>. The reason for this is that I use BigPond as my  
internet service provider, and thus use their SMTP server for outgoing  
mail. However the return address is hosted in the USA, being where I  
have my web site hosted (at futurequest.net). Possibly the mismatch  
between sender and return address is responsible for the blockage.
