Dear Rick / GNUperts
I am a very enthusiastic GNU-emacs user and just wanted to start using
the send-mail feature instead of unix mail.
You promised that a .mailrc file is scanned for aliases and these
would be translated by EMACS.

I am sorry that this is not the case here.
We are running emacs-version
    GNU Emacs 18.47.3 of Fri Dec 11 1987 on stuart (berkeley-unix)
on a small IBM-RT network.
I did not have any problems with anything else before.
Following is my .mailrc file to the end of the msg.
Can you give me any advice ?
-------------  .mailrc follows this line --------
