choosing "reply-to gateway" requires an email address

Action:

Sending email and getting the reply via the gateway (over rf).

Issue:

On hitting "send" I get an error saying invalid reply-to email and to enter a valid reply-to email address and try again.

Test results:

Upon testing I found that after entering a reply-to email you can choose reply-to gateway and send the email. I then verified that replies do get routed through the gateway station and having to enter a reply-to email seems like a bug.

Thanks-

Clifford
