I need to create a filter that will match messages having a [just_numbers_here].zip file attachment.
So the filter should match messages having a 1.zip or 23456.zip file attached, but not match messages having a a123.zip or 12c3.zip file attached.
In other words, the attachment file name must consist of numbers only, and the extension must be .zip
What to enter for a file mask to achieve this?
Thanks
