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

[Tóth András]

Hello everyone,


I am using MailMate 6272 with a mailbox.org account, and I am running into a fundamental problem when trying to export my emails in decrypted form. I am hoping someone on the list might have insight or experience with this setup.


My mailbox.org account uses Mailbox Guard, which applies server-side encryption to all incoming emails. While I can read my emails normally (via webmail and in clients), any attempt to export them (MBOX/EML) results in files that remain fully encrypted.


What I have tried so far:


Exporting emails from IMAP clients (Thunderbird, MailMate) → exports remain encrypted


Offline/local IMAP storage → still encrypted


Client-side OpenPGP / GPG-based decryption workflows → not possible, as the client never receives decryptable PGP blocks


Looking for a Guard-side “decrypt/export” option → none available


>From what I can tell, Mailbox Guard decrypts messages only at display time, and the decrypted content is never exposed to IMAP/POP3 or export tools. This makes it impossible to obtain plaintext emails client-side while Guard is enabled.



My question to the list:
 👉 Is there any known workaround in MailMate (or elsewhere) to export emails decrypted when using mailbox.org Guard, or is disabling Guard and performing server-side decryption the only possible solution?



Any guidance or confirmation would be greatly appreciated.


Thank you in advance,

Andras
