Hi!
I have the following thing I want my Gnus to do, but before I set out
to try it I want to know whether it can be done with juistifyable
effort (my lisp is a bit rusty ....):
I'm receiving mails from a message board software (and a filter sorts
them into a separate folder). Obviously the sender address is that of
the MessageBoard-software. Each mail starts with the message
"This was posted by Isidor Pepranek on Tuesday..."
(the name variies obviously)
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)
This worked perfectly apart from the fact that I had to insert a test
whether name was non-nil, otherwise all non-matching mails would have
been tagged with a "From: nil <MessageBoard@>". So the finished function
reads:
(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 nil)
name)
(goto-char (point-min))
(search-forward "\n\n" nil t)
(setq endofheaders (1- (point)))
(re-search-forward "^Posted by \\(.*\\) on [MTWFS]" nil t)
(setq name (match-string 1))
(if name (let ()
(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-"))
))))
(I'm not posting that to show off my weak lisp-skills or to point out
errors in the postings of people that saved me a lot of time by giving
me a good start, but for the sake of the next one who has a similar
problem and knows how to google)
