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.
