Still valid.

And I would like to extend this feature wish by something that is technically
very close:

Keys get revoked. And of course, you never know when. The moment a key is
revoked all its signatures become worthless – unless you can prove (or be sure
if it's for yourself only) that the signature was made (long enough) before the
revocation. The protection if IMAP accounts is many orders of magnitude weaker
than that of crypto.

Thus it would be nice if KMail was able of signing incoming emails. Technically
it is AFAIK not possible to sign an already signed email without breaking the
message format but instead an additional IMAP mailbox could be created where no
email format messages are stored but simply the detached signatures of the
normal emails. Those signature files could be named by the message IDs or by
the hash values of the emails (or just of the signed part). The last step to
happiness would be to prepare for further handling of these signatures by the
option to deliver them locally to some program / script (which may request a
crypto timestamp from a third party in order to be able to really prove that
the signature is valid in case it gets revoked later).

Thank you for your feature request. Kmail1 is currently unmaintained so we are
closing all wishes. Please feel free to reopen a feature request for Kmail2 if
it has not already been implemented.
Thank you for your understanding.

That's a strange argument as far as IMAP storage is concerned. Please mind that
more and more people switch from POP3 to IMAP. There is no other option for
protecting data on IMAP. It would be neither a program-specific backend
(because you can use GPG for any kind of data) nor be new as kmail already has
the capability to decrypt and encrypt emails. The only change would be to
encrypt a received mail instead of a sent one.

Correct but irrelevant as this is not an option for those who use an IMAP
service provider (does not make sense to propose everyone might set up his own
IMAP server just in order to get around this simple and elegant solution by
forcing volume encryption to become an option).
