Re: FQDN via DHCP, then used in exim4
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.
