Bounced Email Info Not Found

Support
6

It is annoying this is not listed in the instructions when setting up VERP. What is more irritating is that the bounce error codes are in the database but are not shown on this screen.

If you use AWS SES, then run the following query in Data Explorer:

SELECT * from email_logs where bounced=true order by id desc

Look for the column called bounce_error_code. The error code can be crossed-referenced with:
