upgpverify: email signature handler

How to install upgpverify

The ugpverify program

upgpverify verifies a PGP signed or encrypted and signed message on stdin, checks the user id or key id against a database, if wanted, and starts another program, providing the payload of the PGP message on an own file descriptor.
upgpverify is designed to work under qmail. It can handle MIME and non-MIME (traditional PGP format) messages. It handles base64 and quoted-printable.
upgpverify also sets a few environment variables containing various header of the incoming email.

Supported PGP / GPG versions:

The ugprules program

upgprules is used to compile rules for upgpverify. Rules, if used, may allow or deny access for certain keys, and also set environment variables.
