Joe,
Yes, I've set the "A" and the "MX" record to the same FQDN, and that is
also the HELO string. (at least now that I adjusted the entry in the
hosts file.)
Thanks,
Klaus

Apart from any other issue, please note that the HELO string provided
by your mailserver really needs to be a hostname which can be resolved
in *public* DNS. On the assumption that you're not running your own
public DNS server, then you will need an A record with your domain
host. It's easiest if you use the same A record your MX points to,
though it's not necessary. Not all mail servers will require their
senders to have a resolvable HELO, but many will, including my exim4.
It's disabled by default, I think, but it's a useful spam reduction
technique. Oddly, some of the pickiest servers now seem to be Exchange
installations.
