Postini Users: How to Allow Bounce Notification Emails

If you are using Postini to host your incoming email, you may need to adjust your Null Sender Disposition settings (within Postini) in order to allow bounce notifications from SMTP2GO to be received.

We recommend that you set Null Sender Disposition to Ignore, which will mean that bounce notifications from SMTP2GO will not be blocked by your Postini filter. We send bounce notifications from a blank sender address.
