[BUG] UNCHECKED contents in mail FROM with PGP encrypted email

Miscellaneous first checks

• I checked that all ports are open and not blocked by my ISP / hosting provider.
• I know that SSL errors are likely the result of a wrong setup on the user side and not caused by DMS itself. I'm confident my setup is correct.

Affected Component(s)

I think this email is sent by the antivirus scanner.

What happened and when does this occur?

Send a pgp encrypted email.

What did you expect to happen?

Find a way to suppress these UNCHECKED contents in mail FROM emails because encrypted emails should be unchecked.

How do we replicate the issue?

1. Guessing: Set up AVIS
2. Send a PGP email

Start by reviewing issue #682 and its referenced wiki content, then reproduce the behavior with AVIS and a PGP-encrypted email in the Docker setup. Determine where the UNCHECKED contents in mail FROM message originates and verify that suppressing it does not affect encrypted mail handling.
