Iphone mail not showing notifications

Hi,

I have rules in my mail app that moves incoming mails to specific folders as soon they arrive. The problem is that in my iPhone I am not getting notifications when a new email arrives. I have to open the mail app in the iPhone to see if there is new emails.

I noted that this issue is only present for those folders that get the emails depending the rules, the emails without rules or the one that arrive to the incoming box and are not moved to another folder are triggering notifications.

Is this a normal behavior or is there a setting to get notifications even when a email moves to a specific folder following the rule settings?

Best regards

Americo
