[ale] sendmail configuration

[Lightner, Jeff]

In your sendmail.mc (typically in /etc/mail) look for line:
dnl define(`SMART_HOST', `smtp.your.provider')dnl

Remove the dnl at start (this is "do not load" which essentially
comments out the entry).   Then replace the "smtp.your.provider" with
your Exchange host.

Then run "make -C /etc/mail" - this will recreate your sendmail.cf.
(Note you need to have both the sendmail and sendmail.cf packages
installed - Sendmail by itself doesn't include the ability to make
Sendmail.cf.).

As noted by Chris your Exchange server has to be configured to allow
connections from the Sendmail host.

Try the smart relay option in sendmail.

You may experience and issue where the Exchange server requires 
authentication of SSL.  I've written a PERL program to send mail using 
these setups.
