Exactly :)

The only tricky case is explained in (info "(auth) Help for users")

   The typical netrc line example is without a port.

     machine YOURMACHINE login YOU password YOURPASSWORD

   This will match any authentication port.  Simple, right?  But what if
there’s a SMTP server on port 433 of that machine that needs a different
password from the IMAP server?

     machine YOURMACHINE login YOU password SMTPPASSWORD port 433
     machine YOURMACHINE login YOU password GENERALPASSWORD

I hope that helps. Closing this as done, but please let me know if the
auth-source manual or docstrings need improvement.

Thank you
