Finally a grep in my archive helped to found matches with Roundcube 1.1.7 and 
1.1.9 all sent in 2017.

With the mail address I remember the person and how they do encrypted mail 
communication. The person used RCube to send/receive mails, but do the 
encryption on a air gaped device and used openpgp to encrypt the files on that 
device and send those encrypted files as attachment named xx.pgp. Those files 
were are not armored. 

RCube interpreted those attachments as text/PGP instead of application/octet-
stream. So it is not a client that used those content-type but a php mimetype 
parser function that returned text/pgp for an encrypted data blob.

Because I didn't wanted to use the commandline too - I added the support to 
handle text/pgp successfully.

Regards,
