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
(http://www.acme.com/software/mini_sendmail/), though this was a while
ago but I seem to recall having some success with it.
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.
