Bogofilter is keeping the key:

   Encrypt your mail: my GnuPG key ID is 0x052E7D95

but not the signature (iD8...):

   -----BEGIN PGP SIGNATURE-----
   Version: GnuPG v1.2.4 (GNU/Linux)

  iD8DBQFATv1KvmGDOQUufZURAq0mAJ0S5mW1EY/hfZHIbijnMkzj2G6G1wCfS0cq
  urzTCKWVJcZ3enAvxZzd/Tg=
  =TZIV
  -----END PGP SIGNATURE-----

The key is a useful identifier.  The signature is different in every
message.
