Andrzej,

1) Thanks for that temporary failure line. I'd forgotten I should have it 
in there.

2) The DNS record for the virtual domain's host name is an A record exactly 
because of that reason. The reverse lookup, of course, returns the 
canonical host name of the primary mail server under which the virtual 
domain is running. Thanks for the reminder about that, though.

Will
