[Evolution-users] Encryption problem - need help

[Cyril Soler]

Well, normally (and according to RFC4880) it should be possible to
encrypt for both the recipient and yourself, so that you can read the
mail that you sent using your own key. Thunderbird+enigmail does this
for instance. 

I suppose that feature is simply not implemented.
