On Mountain Lion's Mail, I am having a problem with the messages I send to a particular coworker from my work account not appearing in the Sent mailbox.
- The messages are going through. (I got her to Fwd: the important one back to me.)
- Messages I sent to my other accounts, even from that account, are correctly appearing in Sent.
- Messages I send from another address (even using the same SMTP server) are appearing in Sent.
Things I've tried so far:
- Connection Doctor. It shows no issues.
- Deleting + recreating the account.
- Rebuilding the mailbox.
- I'm familiar with Use This Mailbox For > and it is not a factor here.
