Send Return-Path to Custom Check Interface

[mbrother]

Hello,

As document https://pmg.proxmox.com/pmg-docs/pmg-admin-guide.html#pmgconfig_custom_check, only api-version & queue-file-name send to Custom Check Interface. A very important information to analysis email is Return-Path, I can not get it with my custom script. How can I get Return-Path for my custom script?

For most mails this should be already in the mail-body IIRC (in the Return-path header)

What's your use-case where this is necessary?

Hi Stoiko,

Thank you for your reply. This is all contents of mail sent to my script:

Received: from source.smtp.local (unknown [10.10.10.10])

As you see, Return-path header is missing. I need this header because this is real sender (email after MAIL FROM command)

Hi Stoiko,

Do you have any idea for my case?
