Using `nnmail-prepare-incoming-message-hook' should work, I think.

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 <via-MessageBoard@YourCompany.invalid>\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.
