Problem interoperating with PGP Universal?

[Blumenthal, Uri]

David,

Are you in touch with Enigmail developers? Or should I post your question on Enigmail list?

And thanks for jumping in - there is no further response to my original question at Enigmail forum (besides recommendation to talk to GnuPG developers).

That's just a regular signature.  How does Enigmail call GPG to do the
verification?
