Decoding message in PHImail

OK. I am receving direct messages via PHImail and the envelope does not have any errors and it’s valid.

However, the message is encoded in base64. If I copy the encoded string to a text file and then run: “base64 -d test.txt” I get a nicely decoded legible output.

So:… why isn’t OpenEMR doing this for me when I view the Validated Document? Do I need to set something up?
I am running OpenEMR v 7.0.0(1) on Ubuntu Server 20.04 LTS with Apache/PHP/MariaDB
Thanks in Advance!
