I can do fine-grained filtering of existing requests by using the advanced ALL/ANY conditions, but this option is not available for mail rules. I also know I can do a second level of processing via the automated tasks, but it would keep things a little cleaner if I could do all the mail processing I need directly in the mail rules.
To illustrate one particular use case, I’d like to do something like:
((Mailbox == “mailbox name”) && ((To == firstname.lastname@example.org) || (Subject == “foo”)))
This would be helpful for people like myself who have a large number of email addresses for various things aliased to a smaller number of actual mailboxes.
