NethServer Version: 7.9.2009
Module: postfix, dovecot
We have recently started using Nethserver as our mail server and would now like to connect the SecurePoint UMA as our mail archive.
Unfortunately, I have not yet fully understood how to insert the X-Envelope-TO headers so that the archive can assign the emails.
I have created an archive@ mailbox and activated “Forward a copy of all messages” in the settings.
The only thing I have found on the subject is already 11 years old and I am not sure how to implement it with the e-smith templates.
You can fake it in the SMTP server with
/(.+)/ prepend X-Original-To: $1
Thanks for your help
