I have had one heck of a time trying to get SMTP relay to work from a copier to office365 exchange account, but I got it working. A quick synopsis...
We are an organization planning to migrate from a local Exchange 2003 box to an office365 hosted solution, and then decommission the exchange server. One of the challenges presented in this regard was the fact that some of our corporate copiers did not support the required TLS encryption to connect to O365. The answer to this problem I'm told is to set up an SMTP relay on one of our other server boxes. I followed KB article for microsoft (http://support.microsoft.com/kb/2600912
), which left out some important details, but I DID successfully get Relay to work. I am able to send messages from the copier.
The problem is, the relay is SLOOOW. Messages sit in the queue for 5-30 minutes before finally getting delivered. (C:\Inetpub\mailroot\Queue
What do I need to do to get these messages to deliver faster? any ideas?
