Why did you decide to make outgoing email delays a rule instead of an email account option? The change is a bother because it has no benefit and only costs. All outgoing email is now delayed, and I used to set this option by account, so I’ve lost flexibility. In addition, outgoing email is delayed rule is satisfied. In earlier versions I could force the email to be sent by clicking “send all,” which I often want to do. Therefore, I’ve also lost an important piece of control I used to have.
Changes that result in less flexibility and less control with no balancing benefit make me very, very cranky.
