Can anyone explain why this rule:

  (to "carbon-emacs@googlegroups\\.com" "googlegroups.carbon-emacs")

matches and works fine, but this rule:

  (to "\\(.*\\)@googlegroups\\.com" "googlegroups.\\1")

sends the message to "googlegroups." ?

                                        Be seeing you,
                                          norm

Does "\\([a-z0-9_-]+\\)@googlegroups\\.com" work?

Bye, Reiner.

I don't know.  I tested with:

(let ((a "tzz@googlegroups.com"))
  (when (string-match "\\(.*\\)@googlegroups\\.com" a)
    (debug (match-string 1 a))))

and got "tzz" so something is interfering with the matching.

Gnus does the matching via re-search-backward with a regexp that looks
like ^\(\(FIELD\):.*\)\(VALUE\)
