Error "<#5.5.2 smtp;554 5.5.2 Invalid data in message> #SMTP#" when you send attachment in your mail

Just to clarify what "Local IP Addresses" and "Remote Servers" are (from Exchange 2007 help), because I find it little bit confusing: Use these local IP Addresses to receive mail Use this list to specify the IP addresses and port numbers on which this Receive connector listens for incoming mail. Receive mail from remote servers which have these IP addresses Use this list to specify the remote IP address range fr…
