Mail which be filtered to other folder can't get notification on iPhone

Hi, 

I found if a email received which be filtered to other folder, this email won't get notification.
But if a mail goes to Inbox, the notification is normal.

My zoho mail is woking under the IMAP and SMTP protocol, with Apple Mail applicaton.

How to resolve this problem.

Thank you.
