exchange 2007 error 5.7.1 unable to relay Davisburg, Michigan

In order to resolve the problem in Exchange 2003, you need to implement a few restrictions on the SMTP virtual server. The essential Virtualization resource site for administrators. They can send to other Exchange users in our organization, but cannot send to people outside our Exchange server. Mail is coming in on these POP accounts but I get 550 5.7.1 Unable to relay error message when I try and respond to an email from these POP accounts.

Root Causes for 'unable to relay Error'! •When the outgoing mail server is unable to recognize the sender. •When the sender is unable to authenticate on the server which restrict them The client connector should only have (default settings) permissions set for Exchange Users, port 587, make sure the FQDN of your server is entered and authentication is set properly for your Cannot Send emails back out from internal client (Outlook).

In the Relay Restrictions dialog box, click OK .

Administrators kept insisting it was a client problem... Re: the above post. They need to be added as a permission group. Is it your server issuing the SMTP unable to relay response or is it an external server that is causing your server to generate the NDR?

What this means is that you have complete trust that the previously designated IP addresses will be trusted by your organization. Now customize the name of a clipboard to store your clips. If you already have the domain named listed in the Accepted Domains List then this could mean that POPcon isn't actually talking to Exchange SMTP but to some other SMTP service Reason your external IP address keep blacklisted. Just permit SMTP traffic only from your exchange server and block SMTP for other hosts in your firewall.
