BTCrow Won't accept .info email addresses?

[Zylian]

Tried to start an escrow session with a seller who has a .info email address but BTCrow gives an error saying the email address is invalid. The email address is not invalid, I've been exchanging emails with them.
I tried two .info addresses, both 'invalid'.
This renders doing business with sellers who use tormail.info impossible with BTCrow.
What gives?
