[Mailman-Users] Training Mailman to find email address from NDR

Wed May 15 09:45:15 EDT 2019

Hi,

As part of some upgrade projects I am testing using a transactional email service (Sendgrid) and have eventually got bounce forwarding working.  However Mailman is not seeing the address in the bounce so is forwarding it to the list owner.  I am probably not going to use Sendgrid long-term, as they seem to have a worse reputation than our static IPs, but wanted to know if I could get Mailman to process this bounce somehow?

Here is the bounce message, I know I can enable VERP and this problem should go away, but I wanted to see if I could get this working without VERP as we have a large mail traffic on the list.

Thanks.
Andrew.
