----- Issue -----
Some outbound messages are bounced with an error containing the following text:
reinject host refused rcpt to: - psmtp
----- Resolution -----
This error is thrown by Perimeter Manager when it attempts to reinject an outbound message and the reinjection server refuses the message. This is a permanent failure; the message is not reinjected and not deferred, but returned to the original sender.
To correct this, you will need to reconfigure the reinjection server to allow Postini's IP addresses to relay mail to it for external recipients. This is a requirement to use Perimeter Manager outbound.
----- Additional Information -----
This error occurs when the reinjection server defined in the Outbound Servers tab of the email config handling the outbound traffic for the domain or user refuses a message. The text noted above is added by Perimeter Manager to make it clear that the error was thrown during a reinjection attempt. Actual errors may be similar to the following:
550 Relaying is prohibited - reinject host refused rcpt to: - psmtp
550 Relaying not allowed - reinject host refused rcpt to: - psmtp
550 5.7.1 Domain invalid - reinject host refused rcpt to: - psmtp
550 5.7.1 Unable to relay - reinject host refused rcpt to: - psmtp ##
The first part of the error is what is being thrown by the reinjection server.
During initial outbound configuration, Perimeter Manager runs a reinjection test to ensure that the reinjection server allows relaying to external recipients. This configuration would have to have been completed successfully for the test to pass, so the configuration of the reinjection server was changed at some point after initial configuration. This test is only run once during initial configuration; Perimeter Manager does not continuously check to make sure that the reinjection server is configured properly. It is the responsibility of the mail administrator to ensure that configuration changes required for Perimeter Manager outbound remain in effect.
