PGP Messages from Eudora 4 reported as invalid

Question

All message written with Eudora 4 containing a PGP signature fail to be sent because of an invalid entry in the message header.

Answer

The problem is that Eudora 4.0 is adding this line:

—–BEGIN PGP SIGNED MESSAGE—–

…without first putting a space between it and the header. This makes it
PART of the header, so NTMail GMS Mail sticks it’s X-Info right after it, like it should.

The bug is due to Eudora 4’s PGP implementation, not GMS Mail. Incidentally,
the bug exists both in Eudora 4.0 and 4.01.
