Posted by Robert Mitchell on 07 November 2016 11:45 AM

Overview

The error message "#553 sorry, relay of mail is not allowed. (#5. 7.1) ##" indicates that:

  • The smarthost is not configured correctly to send mail via asp-submit.reflexion.net
  • The sending IP of the server is not listed as a trusted host
  • Your IP address may have changed or the IP address you are sending messages from is not in our trusted hosts
  • The sending domain is not sending from a domain listed in Reflexion

You will also see this when you are trying to forward messages to an external domain (ex: yahoo.com or gmail.com). If so, please add the external domains to the permitted relay list:

  1. Log in to Reflexion using your solution provider credentials
  2. Click on Customers
  3. Click on Permitted Relay
  4. Click on New Entry
  5. Add the domain name your customers will be forwarding mail to (ex: gmail.com, yahoo.com) 

*This entry will apply to all of your customers.
