Local delivery, remote delivery, who cares? Mail is being transferred.
If you want to use sendmail as a point of reference, then yes, sendmail
does handle local delivery. It does so with exactly one delivery
mechinism: the pipe.
I would argue that the MTA (mail transfer agent) has nothing at all to
do with SMTP (simple mail transfer protocol), which is simply a
mechanism for clients to talk to servers and for servers to talk to
other servers.
What if I run sendmail in such a way that it's not listening for network
connections? Is it still an MTA?
