Hi,
I have been using zentyal for over three years and am very happy with it.
But now I have a problem when I send emails to some exchange servers that don't respond with the close command after an smtp session.
To fix it I added smtp_discard_ehlo_keywords = pipelining to the postfix main.cf file, but every time zentyal restarts this setting is lost.
How can I make it permanent?
All custom settings added with version 6 worked, now with 7 , all new settings added by hand, are lost.
Can you help me ?

There are specific configuration files that manage Zentyal like main.cf. To modify them, you must use the stubs. Below you have more information.
