Hi Adrian,

my intention with #2 is to permit gnucash.org as an authorized sender of 
messages from chilwell.net,....I'm not proposing to route the list through my 
server.  I'm not that daft!

I'm still learning, but I think the messages are failing after the listserv 
reflects out to the membership.  GC gets the copy, but then maybe Liz or Derek 
see bounces from [member at recipient-domain.com]? ....don't wanna annoy Liz. :-0

#5 seems likely...

thanks.
Maf.
