Sorry, I realized I wasn’t clear in the title. I can mark them as read but I wanted to see if it can automatically mark itself read, since as you stated, I sent it! 🤣
The email rule I set up to mark it “read” doesn’t do it.
Maybe rules don’t apply to me! 🤔😉😏
I did understand the problem from your title and just tried to understand what could be Mail.app's "reasoning" for not applying the filter, or "Rule" as Apple prefers to call it.
Do you have more than one email account?
Can you try Bcc or Cc to a different one than the sender and see if the rule will work on that?
I have noticed an odd behaviour in Mail perhaps related.
If I Bcc myself the original "sent" email dissapears and I'm left only with the received Bcc copy.
For example; I send an email to
you@yourdomain.net from
me@mydomain.net with a Bcc to
myself@mydomain.net
I want to keep a copy of my sent email in the
you@yourdomain.net Mailbox that I've previously set up and have been using for our correspondence, but, I can't find my sent original from
me@mydomain.net so only have the Bcc sent to
myself@mydomain.net to transfer to that Mailbox.
I just assumed that Mail.app sees duplicate messages and so deletes one, but I can't see the missing email in the sent mailbox, bin or anywhere else, and AFAIK there isn't a setting to delete duplicates anyhow.
It's puzzling but I've learned to live wth it.
