Hey, thank you for looking into this. 

Without doing the diagnostics, I do know that other signed messages are
handled properly, almost always with the warning that the key isn't
known. 

Two issues arising:: 

1. Does Evolution have any tools or support for downloading public keys
etc? I've used such a capability in other email clients. Do I need to
learn how to use gpg directly at the command line? 

2. How can I get a later version of the binary for Evolution? My
Debian-based distro (LMDE) offers only 3.30.5-1.1. 

Thanks!
