I see the "Client Circle" option, but according to the manual, it can only send to the customers and/or resellers. This is a little ambiguous since customers could be referring to just the named contact for the client but then again it could be referring to all mailboxes of the customer? Please can you clarify this point and indicate how to perform each of those options? Many thanks.
Ah okay. I was thinking I could email all users of a domain, through ISPConfig to advise of system maintenance, but it's okay. I will just export the relevant mailbox addresses from the roundcube database and email them manually. Thanks.
