I'm not sure that would have solved my specific problem (which I may
not have described too well). I just tried it, and it doesn't look
like it would work for me. In order for it to work, I would have had
to be able to:
echo "some message" | mail wpd@[mycompany.com] -s "test"
and add the internal IP address of our SMTP server to my /etc/hosts file.
In that manner, sendmail would not look for the MX record for
mycompany.com (because it was in brackets) and would, instead, find
the internal IP address from my /etc/hosts.
That is precisely the sort of solution for which I was looking,
assuming that it worked.
I just tried this and, my sendmail didn't like the @[mycompany.com]
syntax in my email address.
Instead, putting in the internal IP address of our SMTP server as the
SMART_HOST, solved the problem, though not in the manner I was
Anyway, thank you again to the folks who responded.
