    Unable to Relay Errors

    strongmantech

      Starting Monday, I have had numerous clients using McAfee Email Security report rejected emails that state:

       

           550 Validating Sender: bosauthsmtp17: Host ipaddress: No unauthenticated relaying permitted

       

      or

       

           550 5.7.0 Relay Access Denied

       

       

      These are all emails that they've been able to email in the past. All rejections are coming from: MAILER-DAEMON@p01c12o148.mxlogic.net.

       

      Sometimes, they can resend and it goes through, and for some, they cannot. I beleive this is part of the System Change over the weekend. I will be opening a support ticket.
