On the other hand, the version of sendmail in ports can be compiled with all the different bells and whistles enabled. If your machine is configured as a smarthost MTA, then generally you'll want to install one of the more fully capable MTA packages from ports -- sendmail, postfix, exim etc. For most other setups, a machine does not need to do anything more with e-mail than deliver locally generated mails (from cron or whatever) either to a local mailbox or to a smarthost. Hence the current sendmail in base is neither fish nor fowl: way overpowered for almost all installations, but with significant limitations for a machine providing a full-blown mail service. Personally I agree with his reasoning: unless the primary function of your FreeBSD machine is to be an MTA, you really don't need any more capability than to either deliver to a local mailbox, or forward all e-mails to a smart host. Certainly you don't need anything capable of receiving incoming e-mails.
