DMA is a much smaller and simpler mail server which offers a deliberately limited subset of the full functionality of MTAs like sendmail, exim or postfix. It's suitable for FreeBSD servers that aren't specifically for handling e-mail but do need to send some messages occasionally. It doesn't handle incoming e-mail at all: it's ideal role is to hand-off e-mails originating on your server to a central mail host for forwarding or delivery. So, if you need a fully fledged mail server, need to receive messages from remote senders or simply prefer the added functionality and complexity then DMA is not for you. AFAIK, sendmail is still going to be supplied with the base system for the forseeable future, but honestly even if it does get removed from base, it certainly isn't disappearing from ports.
