Adding "mail" function?

I've just installed the emBSD 1.1 onto my 4501 unit and in general I love
it!  About the only function I am missing is the "mail" command which I'd
like to use for sending copies of various logs to an email address before
flusing them.  Since I'm still a bit new to this *BSD world, can anyone
offer me tips on how to get the mail command (and all of its associated
files) moved over?

Thanks,
Peter
