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.
