mdp -go bounce address issue

[Jason]

hey,

i have an issue i have been really unable to resolve.

the return path, bounce address when only using mdp-go is wrong and not the one specified in the MW bounce server.

for some reason the mdp-go process is combing the smtp username and the server hostname to create a return path address, and the correct bounce address is pushed into the x-sender header

i've tried playing around with it on PMTA and mail-tester but not getting anywhere near a solution

any ideas? Not sure why this is happening.

i should add that pmta cannot set headers, whilst i can try limit them, it is the feeding application that is doing this for some reason

thanks

@Jason - Things is MDP itself does not set any return path header.
If you take a random email from the pickup directory, does it contain the right headers?

 

[Jason]

Yes, I know which is confusing as to what in mail wize is putting this random return path together.

Username@hostname.com

Yes all correct apart from the return path email address. The bounce server email address is being pushed into x-sender header

I have nothing left to test as far as this goes.

When sending from as a normal smtp server, using the same details, it is fine

still trying to investigate this but im quite at a loss, this occurrence has happened on 3 seperate servers now and i cannot fix it.

^ This is written by me and that's how i know it isn't mailwizz fault, because when the email leaves the MDP daemon there the second return-path does not exists, it's added afterwards, at least this is what happened in the above scenario as far as i can remember.
If this gives to much headaches, maybe you can look into this instead.
