Email Messages Input Query

I tried filter option for Email Messages Input plugin and its not working. Instead of filtering mail to be retrieved based on “FROM” and “TO” , it retrieves everything.

Did you checkmark the item?
If checkmark is not set, it will not filter by that line item.

I only added the sender and checkmarked it. But still it didn’t filter according to the sender.
I am using IMAP protocol and my “use SSL” is checkmarked in the General tab.
