I do not see an MX record listed in my forward look up zone. Is it required? Will adding one hurt anythong? For the most part, our email system (Exchange 2003) works fine. We even have a printer that can send a scan to a computer by way of SMTP and that works fine. However, we have an inbox account in Outlook 2003 that is setup as IMAP4/SMTP. We can receive emails to this account but cannot send emails from it. Would this even be related? (Especially since the printer can send email by way of SMTP).
