My desktop computer time was messed up (it came back from repairs)- I 
 fixed it.

What does this mean to have an entry in this table? What is a relayhost 
(is it my backbone provider's
smtp server) ?
 If my machine (say x.com, is hosting mail for y.com & z.com), what
would be the entries here?  Would it be:
.x.com    esmtp:smtp.earthinlink.com
.y.com    esmtp:smtp.earthinlink.com
.z.com     esmtp:smtp.earthinlink.com

Do I simply put this line anywhere after:
#
#  Parse1 -- the bottom half of ruleset 0.
#

SParse1

After looking the sendmail.cf, this doesn't seem to be a trivial item, 
there are a dozen or so rules that
look completely incomprehensible to edit.

The concept is really simple: no mail goes out of this machine, except 
via POP3 - mail never originates
from it.

Isn't there a preprocessor variable that can be adjusted, instead of 
editing the sendmail.cf
directly?

Are there other smtp type programs that simply receive mail and never 
forward, relay or allow
sending of  anykind?


Thanks again for your help. I appreciate it.
