imapsieve and master user

Hello all,

I have am imap sieve script, running fine.

I would like to check, if it is possible, inside the sieve script, if the current user is a master user or not. I believe this is probably not possible.

Otherwise, if it is not possible, I would like to check for an external condition, like an existing file in /tmp or in the mail dir folder, for instance.

The issue is that I want my imap sieve script behave differently if the master user is connected.

Thanks for any piece of advice.

Kind regards, André Rodier
