address@hidden: in ~/.mh_profile side effect -- "from:" aliases no longer expanded by send

[Tom R]

If I put a line like:

    sendfrom-examplefoo@gmail.com: -server smtp.gmail.com -user 
examplefoo@gmail.com -port 587 -tls -sasl -nomime -msgid -verbose -snoop

into ~/.mh_profile, it works as intended, but then

    send  ~/Mail/drafts/1807                # where 1807 has an alias in the 
from field

fails with the msg:

    send: unable to find sender host /a/moobt/Mail/drafts/1809: Success

# working/non-failing example | profile does *not* have a "sendfrom" line

# failing example | profile **does have** a "sendfrom" line

In this case the line:
    sendfrom-examplefoo@gmail.com: -server smtp.gmail.com -user 
examplefoo@gmail.com -port 587 -tls -sasl -nomime -msgid -verbose -snoop
was added to ~/.mh_profile:

    $ cat ~/Mail/drafts/1809
    From: trxx
    Fcc: sent
    To: truna
    Subject:  test 123
    
    asdf
    $ send -snoop ~/Mail/drafts/1809
    send: unable to find sender host /a/rodmant/Mail/drafts/1809: Success
    $ cat ~/Mail/drafts/1809
    From: trxx
    Fcc: sent
    To: truna
    Subject:  test 123
    MIME-Version: 1.0
    Content-Type: text/plain; charset="us-ascii"
    Content-ID: <3114242.1615812386.1@epjdn.zq3q.org>
    
    asdf
    $

I have several cron jobs that depend on send expanding from aliases, so I had 
to revert
~/.mh_profile, commenting ou the sendfrom-examplefoo@gmail.com: line.
