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 email@example.com and firstname.lastname@example.org. If email@example.com is on a listserv, firstname.lastname@example.org, then the headers show email@example.com as the To: address, and so my filters and identities that look for firstname.lastname@example.org do not trigger. This would also occcur if mail were sent to email@example.com via bcc: whereby some other address would definitely be on the To: line.
Anyway to fix this?
