After several attempts I have created a virtual SMTP relay on a Windows 2012 server to act as relay between our MFDs, LOB apps etc. and Office 365. This is all due to TLS encryption being necessary.
The main issue I have at the moment, is more of a head scratcher than anything else. I have had to create a user/mailbox in our Exchange Admin Portal for our SMTP relay to use. If I created an account in our Active Directory forest no email went anywhere, the account did not work. This was born out by advice from Microsoft.
For the sake of argument I called the account IT @blah.com, with a display name of ‘IT Department’. All email alerts from SCOM or from our MFDs are all addressed from ‘IT Department’. However, I need to be able do something like this:
1. Alerts from SCOM arrive in a mail box from ‘IT Department’
2. Scans from MFDs to arrive from ‘Printer Name’ (e.g. Finance Printer).
The list can go on and on. The problem is that I can only setup one account to authenticate as if I use ‘Anonymous Access’ it fails. See attached screenshot).
How can I set Office 365 up so that I can relay SMTP email for different purposes without having to create multiple SMTP relays and accounts in EAP? I don't want all SMTP relayed email to come from 'IT Department' for example.
Any help please?
