I promise this will be my final question of the day. I enabled three users to receive html bulletins. When I tried to send out a test bulletin - I received the following message:

Sorry! There was an error: Can't send mail because of an unexpected server response. I said "RCPT TO: " and the server replied "501 Syntax error in arguments".
The error was detected by Frontier 9.0.1 in mainResponder.respond. Webmaster: kmurtha at mail.nasboces.org. Time: Fri, 19 Aug 2005 18:52:43 GMT.

Any suggestions?
