Hi Anthony,

To replace a line with Enforce a file content (or with any other technique/generic method that would do replacement), you need that the regexp doesn't match the string you are putting.

So, the regexp you'll need probably is

[#]?mail.recipients=(?!ops@mydom.com$).*

Hi Nicolas,

Maybe it would be a good idea to add an example like this in the documentation. I needed it once as well and fortunatly you were helping me to get it right. To be honest I'm able to do some basic regex, but I'm not a regex guru. :D
