[...] I don't want to open up port 25 and it seems a bit silly anyway to send mail on such a long round trip. Is there any way I can tell sendmail that home.isbd.net is localhost (or 192.168.1.1)? I have an entry for home.isbd.net in my /etc/hosts file which is:-
192.168.1.1 home home.isbd.netbut obviously sendmail is doing a DNS lookup for home.isbd.net which returns the 'external' IP address.
Just had another thought! (I didn't look closely enough at your /etc/hosts entry the first time).
The canonical format for an entry in /etc/hosts is
IP_address canonical_hostname aliases
where as it looks as though yours is
IP_address alias canonical_hostname
which may throw sendmail off the scent. I suggest you try writing it as
192.168.1.1 home.isbd.net home
If that works, then there'll be the question of how it got written wrong in the first place. Often this is done automatically by some system script (which may well be run at each re-boot). So you may have to work round that issue ...
Hoping, again, that this helps! Ted.
