I digged a bit further, trying to decode the emails from commandline with "gpg 
--decode". For some of the inline GPG emails the commandline version fails, 
but for some other it works. Even for those that it works, sup just shows 
undecoded version which leads me to believe it doesn't even try to decode, 
which means it doesn't recognize the email as encrypted at all. 

As far as I can deduct, sup only recognizes encrypted emails if they have 
something like this inside:
Content-Type: multipart/encrypted;
  boundary="nextPart15239034.i9UOPnLxZ9";
  protocol="application/pgp-encrypted"

Or similar. Which is a reasonable behaviour.

On the other hand, if the damned enigmail creates an email with "Content-Type: 
text/plain;" and then proceeds to include "-----BEGIN PGP MESSAGE-----" in the 
body, sup treats this as (no surprise) text/plain and doesn't decode. If it 
tried, it would succeed since this message passed through gpg --decode is 
decoded okay.

So, I guess if this functionality is to be included in sup (and I think it 
doesn't have to be since enigmail just makes broken messages and there's no 
reason why anybody should put up with that:) it should not be in crypto.rb but 
somewhere else, where the decision is made to even use functions from 
crypto.rb (like decrypt) on a message. I'm no programmer but I guess it should 
be something like this:
if payload contains "BEGIN PGP MESSAGE" then run the decrypt function from 
crypto.rb on it. 

For now - does anybody know a way to mass decrypt all messages in my mailbox 
so I can keep them in plain text and use sup anyway? That would be ideal 
solution but I just can't find a program to do that. And gpg itself isn't 
helpful since it just prints decoded payload on --output, without the headers, 
so it's no use in batch. I can try to code this in bash but maybe there's 
something out there already?

Thank you
Piotr
