Is there a way to force the Information Management System to send a different name than the computer name? Example: I'm sending mail to a firstname.lastname@example.org, and his provider's SMTP uses reverse DNS as an antispam feature. My Exchange 5.5 box says "EHLO exchange.mydomain.com," but the ISP finds the reverse DNS to be "mail.mydomain.com" -- so it rejects the connection.
- Launch Exchange System Manager.
- View the properties of your SMTP Virtual Server.
- Switch to the Advanced Delivery tab.
- Input whatever FQDN (i.e., mail.mydomain.com) you need to override the server's FQDN.
Alternatively, you could just change or add it to the MX entry in your public DNS to account for the "mail" host record and "mail.mydomain.com" mail exchanger.
