The Mail Client ( Application ) belongs to Apple and we agree on that.
The emails are coming for the Senders via the email address associated with your email Provider
The Application is doing what the User has configured it to do, Block Sender(s)
You may consider logging into the webPortal of your email service provider
See if there is some setting or filter they offer to Block the email addresses of the Block Sender
In so doing, the Blocked Senders email(s) may be Blocked or Deleted Server Side of this equation and never reach your Inbox.
