Scott,<br><br>I've not done sendmail configs recently, but it seems to me it will look up the ip addresses of each interface to determine the hostname to use in the from address. Does host.dept show up first when you do an nslookup on any of the ips on that server?<br>

<br>
I have not modified <a href="http://sendmail.cf" target="_blank">sendmail.cf</a>. I've never needed to in the past.<br>
<br>
Interestingly, this is the only server in our department that is<br>
<a href="http://host.osu.edu" target="_blank">host.osu.edu</a> and <a href="http://host.dept.ohio-state.edu" target="_blank">host.dept.ohio-state.edu</a>. Although when I installed<br>
it, I'm pretty sure I only used <a href="http://host.osu.edu" target="_blank">host.osu.edu</a> when setting up the<br>
network.<br>

Yes, that is exactly correct.<br>
<br>

<br>
Again, I haven't touched <a href="http://sendmail.cf" target="_blank">sendmail.cf</a>. I've never had to do so in the past.<br>
<br>
I'm not sure where <a href="http://host.dept.ohio-state.edu" target="_blank">host.dept.ohio-state.edu</a> is even entering the<br>
equation here. It's certainly not defined anywhere on the server that<br>
I can find.<br>
<br>
If necessary, I can have that entry removed from the DNS configuration<br>
for our zone, too.<br>
<br>
Thanks,<br>
Scott<br>
