[MlMt] Mailbox.org / Mailbox Guard – exporting emails in decrypted form

[ARC MM]

Hello Andras,

Although not immediately addressing your problem, I would still 
recommend to try  last available test build 6292, I’ve been using it 
since release and is very stable imho.

r6292 can be found on https://updates.mailmate-app.com/archives/

Succes!
