Customizing the SMTP response sent by SpamProfiler action

This article applies to:

• Trustwave MailMarshal (SEG) 8.X
  • This customization is not available in 10.0 and above
• SpamProfiler

Question:

• How do I change the response that MailMarshal SMTP returns when a message is rejected at the Receiver by SpamProfiler? 

Procedure:

SpamProfiler can be configured to reject messages at the receiver (during the SMTP conversation). By default the SMTP message returned is 550 Message refused.

In MailMarshal 8.X, you can customize this message with a Registry setting.

• Changes made in 8.X will be retained in 10.0 and above, but there is no option to change the setting in 10.0 or above.

To customize the refusal message:

1. On the Array Manager 8.X, edit the Registry
2. Navigate to the SEG Receiver key:
   • In version 8.X: HKEY_LOCAL_MACHINE\SOFTWARE\Trustwave\Secure Email Gateway\Default\Receiver
   • For full details of the location for each product version, see article Q10832.
3. Edit the existing value AuthEngineAction.
   • Add the custom text at the end of the value (after the fourth semi-colon).
   • CAUTION: Do not change any other values in the string.
   • For example:
     1;0;;;550 Message Rejected by MailMarshal SpamProfiler
     
4. To apply the change, commit configuration, and then re-start the Receiver service on all processing servers.

As always, take due care when editing the registry.
