I extensively use identities and filters, and they have a short coming whereby they do not trigger based on a mail To: address if the address is not actually on the header's To: line.
For example, I get mail sent to me at firstname.lastname@example.org and email@example.com. If firstname.lastname@example.org is on a listserv, email@example.com, then the headers show firstname.lastname@example.org as the To: address, and so my filters and identities that look for email@example.com do not trigger. This would also occcur if mail were sent to firstname.lastname@example.org via bcc: whereby some other address would definitely be on the To: line.
Anyway to fix this?
