Hi,

Quoting Michael M Slusarz <slus...@horde.org>:

The MIME/IMAP/attachment code has been completely rewritten in IMP 5 and, regardless, the outputted message *is* valid MIME. However, you really shouldn't be using 'Forward Attachments Only' - you should be using 'Forward Entire Message' (I am very close to removing the other 2 options in IMP 5 completely).

The 'Forward Attachments Only' is needed. IMP4 has problems showning
Messages Forwarded "Forwarding Entire Message" if the original Messages contained Attachments and was signed with SMIME. I can't remember if the forwarded message had to be signed that the problem would be shown.

See http://bugs.horde.org/ticket/4297

How will/should IMP5 handle Forwarding signed messages?

It forwards the entire signed message. Thinking about this more, this makes the most sense. If I send an encrypted message to someone, I *don't* want that person to forward that message to anyone else that can't decrypt the message - that message is meant for the the receiving person only (that is the whole purpose of encryption).

Obviously we can't prohibit the receiver from copying/pasting text or downloading/reattaching an attachment in a new message, but this requires active steps on the part of the user rather than allowing simple forwarding via a button.
