Phase Two of the EasyGPG project (Phase 1: T3121)

• Implement an Encrypt filter that automatically encrypts all incoming emails with a selected key (D7041)
• Implement a Decrypt filter that automatically decrypts all incoming encrypted emails (D7041)
• Implement a Re-encrypt filter that decrypts all incoming emails (if necessary) and encrypts them with a selected key (D7041)
• Modify IMAP resource to be able to upload the automatically decrypted/encrypted emails back to the IMAP server (already implemented)
• Modify Maildir resource to be able to store the automatically decrypted/encrypted emails in its storage (already implemented)
• Modify Mbox resource to be able to store the automatically decrypted/encrypted emails in its storage (already implemented)
• Modify MixedMaildir resource to be able to store the automatically decrypted/encrypted emails in its storage (already implemented)
• Extend the Mail Filter Agent to be able to execute filters on all folders, not just Inbox as otherwise we will not decrypt/encrypt emails that were filtered into various folders by server-side filters (D7134, D7135)
• Add "Apply filter to current folder and all its subfolders" action (R92:2d413420d, R206:427550866b40)
• Modify Composer to save Drafts encrypted by default (D7189)
• Error handling
• Investigate key passphrase storage - we don't want to annoy user with hundreds of passphrase dialogs whenever an email is received and needs to be decrypted
• Add encrypt/decrypt actions to KMail's context menu (see the specs for details)

Optionally:

• Modify EWS resource to be able to upload the automatically decrypted/encrypted emails back to the Exchange server (talk to @nowicki)
