Submitting a new port via send-pr seems broken...

[Alan Garfield]

Hey all,

When I try and submit a new port via send-pr I get this from my primary
mail server from the MX at freebsd.org.

Am I doing it right? Or is something broken?

Is FreeBSD-gnats-submit at freebsd.org the correct address of a port
submission?

Thanks,
Alan.
