Two colons—dpkg-reconfigure exim4-config should tell you that, thus:

Not required. I presume a password applies per site rather than per port.

I'm not sure what specific location you mean by smtp transport.
I've used various ports at times, 25, 465, 587, and aliases for 25,
but all made in those two files mentioned.
