This is perfectly reasonable. On the local machine, GPG encryption doesn't add
much security besides the passphrase, if the private key is stored locally,
which usually is the case.
Still, there are a few cases where the user might want to have a decision.
So while Akonadi should cache GPG encrypted mails in encrypted form by default,
caching them decrypted should be an option.
Wouldn't add an option to remote store the decrypted messages, though.

As this would significantly ease up searching PGP encrypted mails, I mark Bug
#28261 as blocking this one.
