Are you referring to sendmail as the local MTA?

It sounds like you are using sendmail as the local MTA to which you refer.
Sendmail is AN MTA.  It can be configured for local use only.

The same sendmail that it sounds like you currently use can also be used as
the phpgw email MTA but "phpgw needs to connect via the smtp port"

The phrase you quote is what gave me the impression that you thought it would
be hard (hard as in time consuming).  However, subsequent posts also pointed
out that pop3 and imap were not required, just smtp.

I acknowledge freely that my experience is limited, but I typically run
sendmail or postfix on my servers and use it to forward system emails to my
main mail server.  They may not accept smtp connections, but they use smtp to
make them (for readers who don't have much experience with email systems, it
is typically the same software, just configuration changes)

At this point I forget what you were originally trying to do.  Was this for
calendar notifications?
