There are lightweight SMTP clients that can be used as drop-in
sendmail(1) replacements by speaking directly to a remote SMTP server
instead of dropping the message in the local queue directory. One that
I've used is mini_sendmail
(<a class="moz-txt-link-freetext" href="http://www.acme.com/software/mini_sendmail/">http://www.acme.com/software/mini_sendmail/</a>), though this was a while
ago but I seem to recall having some success with it.<br>
<br>
Others have mentioned the trade-off between the additional complexity
of maintaining an MTA on each system and the fault-tolerance such a
setup provides, however, you can achieve similar levels of fault
tolerance by implementing redundancy on your relay server system(s). I
guess it's up to you to figure out what's appropriate to your
environment.<br>
