True.  They are the ones that came up with the procedure for 
configuring sendmail.

Is this a need for a mini-howto?

It changes about every 2 days to prevent server stuff being run from home.

I have looked at a dynamic DNS system and this may be the way in the 
future.  At present I don't really care as I sort of like having all 
the system mail separate from my Internet mail.

After I do a full rebuild with FC4 I will be looking at the dynamic 
DNS sites.  (For another reason).

I just wanted to show that there are different problems associated 
with getting mail out.  Some of it beyond a users control.
