for about 2 weeks too many important emails are goung to junk. how can i fix this?

Hi kathi70,

You'll want to take the steps listed below.

Mark legitimate emails as not junk

Filtering out junk mail can block a legitimate email from reaching your inbox.

If you feel that a legitimate email message was filtered out accidentally, you can mark it as not junk so that any future messages from the same sender will go to your inbox:

* On your iPhone or iPad, open the message in the Junk folder, tap the Move to Folder button  at the bottom of the screen, then tap Inbox to move the message.

* On your Mac, select the message in the Junk folder and click the Junk button in the Mail toolbar. Or just drag the message to the Inbox in the sidebar.

* On iCloud.com, click the Junk folder in the sidebar. Select the message, then click Not Junk at the top of the message window. Or just drag the message to the Inbox in the sidebar.

* For other mail clients, move the message from the Junk folder to the inbox.

If you notice that multiple email messages are being delayed, bounced or not delivered, contact iCloud Support. Email messages in the Junk folder will be deleted automatically after 30 days.

Cheers.
