[MlMt] wrong smtp choice

[Randy Bush]

m3/max 14.2
MailMate Version 1.14 (6010)
9c and cloudy

i have three acounts on this host.  two use my smtp servers, one
orifice365

i am in the INBOX of the Sources for an account with smtp of my own
server. i compose
    From: randy at psg.com
    To: randy at psg.com
which should go out via my server.  it goes to orifice365's smtp server

is there some config or tunable i am missing?
