Hi there.
1st of all - great thanks for NS. everything works fine just one thing confuses me.
I’ve created the rule in Roundcube which is working fine but I can’t see it in e.g. Webtop. What is the strategy of the e-mail rules across all web front-ends? How to manage it correctly?
Inbox filtering rules set on WebTop are always written to the sieve server just like Roundcube and SOGo do.
WebTop, however, cannot read rules present on the server and written by other clients.
If multiple clients are used to create rules, different files are created on the server at this location: /var/lib/nethserver/vmail/<mailbox>/sieve/ but only one is active (typically the one last modified).
With Roundcube you are able to see all the sieve files present on the server (even created by other clients) and you can decide which one to activate.
Multiple files cannot be active at the same time.
