first: I did respond on list as well as directly to you.

second: There is nothing wrong with expanding roundcube to print a list 
of online based users. This may be just as easy as printing a certain 
database table of active sessions. Yes, there are security concerns but 
of course these need to be dealt with properly.

third: Yes, it's outside Dovecot's scope, hence the Roundcube 
sugestion.
