Dear Eric,

Just a quick email to tell you that I have just succeeded to configure
gnus-alias https://www.emacswiki.org/emacs/GnusAlias

rather correctly mainly thanks to Fabrice Niessen
https://github.com/fniessen/emacs-leuven/blob/master/gnus-leuven.el
(many thanks Fabrice !)

and thanks to other related web pages. I still do not succeed to use
correctly regular expressions for gnus-alias-identity-rules but,
anyway, at the moment it works correctly for me. It is a very good
tool.

Best wishes,

Jo
