I would like to set up an SMTP mail "store and forward" server using Microsoft's SMTP server that can accept email for my domains in the event that my primary iMail server is temporarily down. I would also like to be able to send outbound email through this secondary server because we occasionally do an emailing to our customers and when this emailing occurs my iMail outbound queue fills and my iMail users can experience a performance hit using IMAP.
I have MX records for the three domains (commarts.com, designinteract.com, and creativehotlist.com) that point to mail.commarts.com as the primary mail server and direct.commarts.com as secondary mail server (higher preference number) and have RDNS records for these two mail servers. The setup seems simple enough: Run MS SMTP on the IP address for my secondary email MX record and this should take care of the "store and forward" part (if my primary email server is unreachable the secondary will take the mail and should attempt delivery to the primary mail server for the number and timing of attempts configured in SMTP properties). I want to be able to send outbound mail through this secondary email server without running an open relay. So in short: 1) I want to be able to receive email addressed to my domains through my secondary server that is then passed on to my iMail primary server. 2) I want to specify an internal IP address that is allowed to send through the secondary mail server's SMTP service. 3) I want to make sure that no email not originating from the IP address specified in 2 above is relayed to any domains that are not one of my three domains. iMail server always accepts email with an internal destination-is this also true of MS SMTP? If no, how does one set up MS SMTP to accept mail to internal domains and deny relaying of mail from external to external domains.
