Thunderbird Filters: How to create a filter with more than one email address to be filtered. (ie what syntax to use to put multiple email addresses in the "text to be matched" field of the filter.) I have a bunch of email addresses that send me various advertisements. I want to filter them all into a folder (redirect them upon arrival after spam checking.) I can get a single address to work in a single filter, but i want all 25 addressed to be acted upon the same way, but i really don't want to have to create and maintain individual filters. I can 't find any reference to specific syntax to delimit/separate each of the email addresses in the single filter text-to-be-matched field. Any ideas?
