2989995 - Output Error "Recipient address rejected ERS Customized Block" After Sending E-mail

Symptom

You are facing this such error message in the output of an e-mail:

5.1.0 - Unknown address error 550-'5.7.1 <XXX@XXXXXXX.XXX>: Recipient address rejected: ERS-Customized-Block.'

Environment

SAP Business ByDesign

Reproducing the Issue

For example:

  1. Go to Customer Invoice.
  2. Go to Invoice Documents.
  3. Open an object.
  4. Go to Output History tab.

Cause

The recipient has a custom E-mail Reputation Service which is blocking the emails from SAP.

Resolution

As the recipient mail server is rejecting the mail from SAP we cannot do anything at SAP side.
You will need to check with the recipient's e-mail service provider and ask to unblock the emails from SAP.

If needed you can send the following IP addresses to be allowed: 155.56.208.100/30, 157.133.97.216/30, 169.145.66.70/31,169.145.66.72/31
