Forward email then encrypt

Hi,

i use mailbox encryption with PGP. I have one alias that emails send to it should be forwarded to other mail provider, then moved into directory and should be encrypted.

I create mail rules:

1. Conditions to Contains mail@example.com.
Actions: Redirect to otheremail@gmail.com, File into INBOX/test
Process subsequent rules checked.
2. Inbox encryption

Emails are correctly forwarded, moved into INBOX/test but as unencrypted form. Can i setup that this emails will be encrypted in my mailbox?
