what has this to do with a horde major release ? its IMPs duty to do that

No way in hell this is even remotely close to a viable solution.  MIME 
fixes are coming in the next major release of Horde.

Currently, when using IMP SMIME/Encrypted messages will be downloaded 
encrypted even tho they are displayed as decrypted.



This is a minor/major annoyance - because users could/have their 
private keys only stored on the IMP server and are not able to save 
the message because its still encrypted.



I've made a small hack (yes its ugly but it will work without 
troubles) to the view.php page (see below).



This works for two reasons : when the users sees the decrypted message 
- the IMP_SMIME object already has the passphrase and the secret key 
cached and you can simply call it again PRE downloading/viewing.



If this message is not an encrypted message it will throw and error 
and proceed normally. I know this is ugly but i do not have a wide 
knowledge of the IMP framework.



However - since this was - just a "2 liner" it could be easily added to IMP

i suggest a similar behaviour for PGP



Alternatly - you could add another button in the user pref bar 
"download decrypted message"
