This requires a "resend" (sometimes called "bounce"...) button on the MUA. you may find plugins/extensions for your MUAs. 4- "forward as attachment". Then your users must understand what this means, and their MUA must forward the original message as a portable attachment (not a mail.dat). Outlook is known to destructively modify messages... 5- "usual forward". Beside the problem described above (message modified), it's not easy to retrieve the original message (quoting, reformatting, only sending one part of among alternate ones, ...). so this only works if the filter has added some "Id". 6- as above, but the filter added an "Id" that helps retrieving the original message. For instance, dspam adds an X-DSPAM-Signature header. 6- additionnal IMAP folders only used for "spam/ham feedback" (users still access mail via POP3, but have an IMAP account to put FPs and FNs on). I didn't test this on outlook to see if the resulting copy is usable. 7- have users copy-paste the source and send it (or paste it on a web form). too much work for users. 8- archive all mail (dbmail is an option), then when an FP or FN is forwarded by some method, try to find the corresponding message. This would use the message-id, the (final) recipient, and possibly other heuristics... 9- use "reporting" plugins in the MUAs. not yet in wide use. ------------------------------------------------------------------------- Take Surveys.
