SBS 2011 Exchange server / POP settings, Error 550 Unable to relay
I have setup a new instance of SBS 2011 Standard
I have updated my DNS/MX records to reflect the new exchange server being now in house.
I can send email without a problem from within the local network. However clients who have their Mail client setup for POP and pointed to the new server are not able to send email, they get the following error:
Your message did not reach some or all of the intended recipients.

The following recipient(s) cannot be reached:

Server error: '550 5.7.1 Unable to relay'
We haven’t cut all over to exchange yet, and wanted to keep the POP settings still active for now, this way users can keep going with their current settings but pointing to the new server via the DNS records update we did.
Any ideas why from outside the network so not using exchange config on client I am not able to send email?
Thanks in advance

I don't understand what you mean by smtp from my country.
Yes I believe it is an SMTP issue. But how do I fix it, I believe it may be an issue where the server will not accept email being relayed through it by users that have their email client configured for a non-exchaneg setup.
Any ideas?

You mail provider may have give you some PO/SMTP settings with the accounts.
Try to set this smtp adress on the client.

Best answer provided...however ultimately I figured it out with some more research. The client access rule was misconfigured
The easiest solution, if you wanna keep pop setting on client would be to set a public smtp from your country on each client. That would solve all your sending problems, unless you have people travelling abroad around the world.
