This is a bug I’ve experienced with Mail.app since at least Mojave, probably longer. If I select an old sent message and hit send again, Mail.app correctly copies the old message into a new draft message with all the right recipients and contents and even attachments. However, it will display a different send account.
I’ve tested this and realized it won’t actually send from that different account, it’s only displaying the wrong account in the dropdown menu. I can manually select the right send account, but that then adds another footer which is annoying because I have to go and manually edit the email.
I can just leave the dropdown menu showing the wrong account, but I prefer not to get used to that since I have several different accounts and sometimes it’s really crucial I choose the right one. Anybody have any idea what’s going on here or how I could fix this? The account it’s wrongly displaying is not the first in the dropdown list, but it is the first account listed in Mail’s prefs. In my case that’s the iCloud IMAP account instead of what I want—most of the time—the Google account I use for work. I can get it to stop doing this by disabling the iCloud account, but obviously that’s not how I want to solve the issue. Any ideas?
