MMDF is probably more secure by virtue of being more obscure if
nothing else. I'm sure we've all been made aware of far more sendmail
holes than MMDF holes but that does not in itself mean that MMDF is
more secure. Historically, it probably has been more secure but
compared to the latest versions of sendmail... it's anybody's guess.
They both have pros and cons. If what you're after is a secure method
of SMTP, I'd suggest checking out TIS's Firewall Toolkit as a start
but there are probably even better options now. Search the web for
keywords like "smtp and secure and minimal", etc. and you'll probably
find some very minimal implementations of RFC822 which should provide
fairly good security.
Paradoxically enough, especially in security, sometimes less is more.
"Hello World" is pretty secure after all. 8-)

Thanks for any help you can give.
