creating email filters
I get a lot of spam mail with addresses that are only numbers. How can I create a filter for them. Each email uses a different set of numbers for the address and the subject matter covers different things. An example is GutterProtectionDeals Partner <30571@579694083661413.com>. Many thanks! Larry
