SPAM on Android EMail App

Is there anything available to filter SPAM on my Galaxy S5 mobile phone (and tablet).

Norton Internet Security controls it well on my PCs with the majority being caught and it is quite quick and easy to add any new SPAM to the filters.

But the standard Android EMail App is useless, you have to copy and paste each address and go through a series of actions to add the address.  I believe there is a maximum of 200 so it would soon be full if I added every SPAM address - about 50 a day.

The final part of the domain is usually common to them all though changes periodically but the filter does not allow you add just a partial domain.

Any chance of Norton adding SPAM filtering to Norton Mobile or can anyone suggest something that will do the job better than the stand EMail App.
