Organisation in the middle

[geomandolyn]

Expected Behavior

Send encrypted Mailtext as attachment

Current Behavior

My organisation manipulates every external mail, inserting a banner "this mail is from external". I have no influence on this. As a result every pgp-mail is broken when sending with k9.

Possible Solution

Sending mail from extern to organisation:
If I encrypt the mailtext and attach this encrypted mail to my mail (k9-client used) I can decrypt it inside the organisation. It would be great if this behavoiur is available by default (maybe for special recipients only)

Context

Some more people have access to my account in the organisation. Some content should only be readable for me. That's why I use this way.

Your Environment

private side:
Android device with k9 mail & openkeychain
organisation side:
outlook with gpg4win plugin & kleopatra

Are you sending via PGP-inline or PGP-MIME? I recall that K9 can do both.

I just tested sending PGP-MIME from FairEmail & Openkeychain and received with Outlook with GPGOL from gpg4win. My company also inserts the external tag in the subject and external warning line in the body. It worked fine.

I also tested sending PGP-Inline via webmail with Mailvelope and received with Outlook with GPGOL from gpg4win. My company also inserts the external tag in the subject and external warning line in the body. It worked fine.

The problem may be with K9.
