All of those clients are using the totally deprecated (like 10 years  
ago) way of sending PGP messages.  It requires scanning the entire  
textual content of the message for "magic" strings, which is very  
inefficient and is disabled by default.  You need to enable pgp_inline  
in imp/config/mime_drivers.local.php

The correct way of sending PGP (or S/MIME messages) is via  
multipart/encrypted (e.g. RFC 3156).  It requires no resources to  
determine whether the message is signed, encrypted, or both -- all of  
this can be determined via MIME types of the subparts.
