You can get by without a server since you are not relaying.
As long as outgoing TCP 25 is open for that device, it can send SMTP unauthenticated to internal users via the external IP address of the mail server instead of the MX record. Just remember to update the IP if it ever changes!!!! From: Lewin, Greg [mailto:[email protected]] Sent: Wednesday, May 18, 2011 1:42 PM To: NT System Admin Issues Subject: SMTP server We have a sister company that recently moved to Hosted Exchange 2010 and no longer have an SMTP server in house. They have a old copier that used to send emails via The old internal Exchange server(5.5). It does not have authentication capabilities, only the ability to send to an IP address. They would like to be able to send mail to their internal users from this device. I have a call into the Hosting company looking for suggestions. I was wondering if you folks might have any ideas.
