Hello, I setup a server with ispconfig3, everything working well, I'll use the server to replace an old server using roundcube & sieve for mail filter, because there are several users wich have their filter for folder I need to import the old roundcube.sieve file in the new ispconfig.sive , I tried to manual modify the file but the changes are not working, there is a way to do this ? Thankyou and sorry for the bad english.
You can setup the managesieve daemon for roundcube to talk to, and I think it (roundcube) can import sieve files; if not, just copy it over in the server cli and then set that ruleset active in roundcube.
