Hi, When I want someone to send me a return receipt, I am used to press `C-c M-n`. All is right for me but now I am trying to obfuscate my 'From' header so instead of a real address, I have a '+something' (ie +mail for mails) or other mark to obfuscate my mail (depending of the mailing list software manager). So taking message-insert-disposition-notification-to function: ,---- [ message.el ] | (defun message-insert-disposition-notification-to () | "Request a disposition notification (return receipt) to this message. | Note that this should not be used in newsgroups." | (interactive) | (save-excursion | (save-restriction | (message-narrow-to-headers) | (message-remove-header "Disposition-Notification-To")) | (message-goto-eoh) | (insert (format "Disposition-Notification-To: %s\n" | (or (message-field-value "Reply-to") | (message-field-value "From") | (message-make-from)))))) `---- I always have to manually remove the '+' part from my 'From' headers. Is there a simple way to advice this function such like it de-obfuscate automatically the 'From' header and so get a good and real email address ? I am not really familiar with advice so maybe can one help me ? :) Thanx zeDek -- In Gruuik we trust
