Hi Mike:
I think this can help you out. The problem by the code returned by the SMTP server doesn't look related to NetTalk
SMTP Error 421. The SMTP error 421 is normally used for temporary problems on the mail server or a problem with the recipients email account. Some mail providers might also return 421 after you reached a limit (restriction) on your mail account (see SMTP Error 451 below).

Fixed in 11.01 which is up, so grab that Mike.
cheers
