Group, I have started getting error messages on accounts when people send mail to an Internet SMTP address that is not the user's Set to Reply address. The Internet address is valid, but the sender gets a Error 550 Relaying Denied. I can't find any good information on these error message from Microsoft. The Exchange server is NT 4.0 with SP6a and SP4 for Exchange.
