Using `nnmail-prepare-incoming-message-hook' should work, I think. ,----[ (info "(gnus)Washing Mail") ] | `nnmail-prepare-incoming-message-hook' | This hook is called narrowed to each message. `---- Untested (and a little ugly): (defun rs-nnmail-fetch-sender-from-body () "Fetch sender's name from body and isert it into the From: header." (save-excursion (let ((case-fold-search t) endofheaders name) (goto-char (point-min)) (search-forward "\n\n" nil t) (setq endofheaders (1- (point))) (re-search-forward "^This was posted by \\(.*\\) on [MTWFS]" nil t) (setq name (match-string 1)) (goto-char endofheaders) (beginning-of-line) (insert (format "From: %s <[EMAIL PROTECTED]>\n" name)) (goto-char (point-min)) (re-search-forward "^From: ") (beginning-of-line) (insert "Old-")))) (add-hook 'nnmail-prepare-incoming-message-hook 'rs-nnmail-fetch-sender-from-body) You could also do it with procmail. The following procmail recipe extracts a line from the body and puts it in the Subject. You need to modify From instead. The original header is renamed to "Old-Subject", see procmailrc(5) or procmailex(5) for details. ,----[ Original ] | Subject: CNN Breaking News | | -- Some relevant stuff | ads, ads, ... | more ads. `---- ,----[ Modified ] | Subject: Some relevant stuff | | -- Some relevant stuff | ads, ads, ... | more ads. `---- --8<---------------cut here---------------start------------->8--- :0 * ^From: .*@(|.*\.)CNN.COM * < 5000 { # Add a Subject to CNN Breaking News :0 BHf * ^From:.*BreakingNews * ^Subject:.*CNN Breaking News * ^-- \/.* | formail -i "Subject: $MATCH" } # :0 * ^From: .*@(|.*\.)CNN.COM $NEWS_SPOOL_IN/local.newsletters.cnn.breakingnews --8<---------------cut here---------------end--------------->8--- Bye, Reiner. -- ,,, (o o) ---ooO-(_)-Ooo--- | PGP key available | http://rsteib.home.pages.de/ _______________________________________________ info-gnus-english mailing list info-gnus-english@gnu.org http://lists.gnu.org/mailman/listinfo/info-gnus-english
