Mail is substituting deleted spam for my replies in personal threads! I can't view my replies in Sent mail! I hope that they are in fact being sent, instead of random political fundraising letters or store ads. But I have no trace of my replies.
I tried Rebuilding Sent mailbox. No change.
Please help. I make my living using this Mac.
