If the user wants to receive mail, that is currently being filtered by Infomail, they can Whitelist the Senders email address. Every Whitelist created and activated by either the user, customer, EveryCloud or a compliance filter, will overrule the Infomail filter.
The Infomail option for new accounts is activated when your mail server has accepted 2 clean emails. For for single/groups of Users, the Infomail is activated when the User has received 2 clean emails. A script is run every 24 hours, at midnight, and it creates the user. Therefore, in some extreme circumstances it can take up to 48 hours for the Infomail filter to start to working.
To de-activate Infomail
Uncheck the highlighted boxes BEFORE you uncheck the activate box, then press "save". See image.
