[OpenLDAP][Authentication][SASL] Complex challenge ahead

There must be some issue which the email server/system. The same email content keeps showing up/bouncing!

Have you run some tests (apart from the simple ones we already know)? Have you sought assistance from your colleagues? Have you read some tutorials (apart from the only one we know about)?

We sent you some examples and test cases a few weeks ago. Some list users have given you useful advice.

My scenario is relatively simple.

Simple but really complex to solve. It is taking a long time!

You lost me here. I don't know what else to do to help you.
