   Why is not "Apache James", which you said listens "for incoming emails 
   on port 25", accepting the connection from the sendmail on port 25?

Maybe sendmail is trying port 25 on localhost and Apache James is only
binding 25 on some other interface?  Maybe sendmail is trying to connect
to some other host?  In any case, I think this is a side issue; the real
problem is to get the sendmail daemon (if a daemon is in fact necessary)
configured for outgoing email only.

   Postfix provides a sendmail binary with limited functionality to fool 
   local applications into calling sendmail to send mail, but that binary 
   instead passes it to postfix "somehow". Question: doesn't Apache James 
   provide another sendmail binary for this purpose?

I'm guessing it doesn't, and didn't, or Marc would have been using it
before his upgrade.  (IIRC he said the Apache James doc said to use
sendmail for outgoing mail.)
