 A MTA (mail transfer agent) is a whole subsystem with its own needs
and peculiarities; it needs to be precisely tailored and configured
for the use you have of it.

 It is quite unlikely that you need to run a full-fledged MTA on an
embedded box. However, if you do, stay the hell away from sendmail.
You will have an easier time with qmail (or netqmail now), which
uses extremely few resources (unlike all other MTAs out there, including
Postfix. I know the choice of a MTA is a highly religious issue, but as
far as the embedded world is concerned, there is just no serious
competition.)

 It is way more likely that you will just need to produce mail locally
and send it to a preconfigured SMTP server. In that case, look at things
like nullmailer or ssmtp, which will be far easier (and lighter) to set
up and use than a complete MTA.
