[NTLUG:Discuss] Sendmail config

[Richard Humphrey]

I have a small network consisting of about 6 Red Hat servers. I have
installed Logwatch on each one and set it to email me with the logs. One of
these machines is our dedicated mail server for company email. After
instructing Logwatch to email richard at xxxxxxx.com from each of the servers
in the network I only recieved the one from the mail server. The rest did
not get emailed to me for the following reason:

 ----- The following addresses had permanent fatal errors -----
<richard at xxxxxxx.com>
    (reason: 553 5.1.8 <richard at xxxxxxx.com>... Domain of sender address
root at rob.xxxxxx.com does not exist)

   ----- Transcript of session follows -----
... while talking to mail.xxxxxx.com.:
>>> RCPT To:<richard at xxxxxxx.com>
<<< 553 5.1.8 <richard at xxxxxx.com>... Domain of sender address
root at rob.xxxxxxx.com does not exist
550 5.1.1 <richard at xxxxxx.com>... User unknown

What do I need to do to fix this problem? Do I need to configure sendmail
locally to forward to the mail server?
