The following KB article describes how to use Microsoft’s SMTP engine in IIS. It is intended to lay out guidelines for how to send email off your existing externally hosted email server. You will need to obtain the following email settings before this can be setup. Your mail server may require certain encryption settings that the SMTP service will not work with. You should contact your mail provider for assistance with the following information.
– Your company specific outbound email server (for example mail.customer.com)
– Your company specific outbound email account (for example ecl@customer.com)
– Your company specific outbound email password (for example eclmail123)
– Your company specific outbound email port (usually tcp port 25 by default).
