Catalina Mail problem. Sender and Subject get swapped with another email

Question

Catalina Mail problem. Sender and Subject get swapped with another email

In the last month or so, I've had 8 or 10 emails that have swapped Sender and Subject with another email. For instance, I'll receive an email from George@xxx.com, but it will appear as coming from Macworld Daily. The email from Macworld Daily will appear as coming from George@xxx.com.

If I click on the Macworld Daily line, the email that appears is the one written by George and also displays the correct From and To information. BUT if I reply to "George's" email, the reply is sent to the Macworld Daily address and with that subject.

This is really confusing behavior. Does anyone know a way to manually type in or correct the Sender and Subject. Right now when I look at my mail list, I can't tell which messages (in this case) are from George. See below for the line I have to click on to see the message from George.

Hello the-design-guy2,

Thank you for using Apple Support Communities!

We understand from your post that the email headings are being mixed up and causing you to reply to the wrong contacts. In a situation like this, try rebuilding the mailbox as described in this article:

Let us know how it goes.

Best Regards.

Thank you Alwayswantingtohelp!

That seems to have cleared up the problem. When I first ran the Rebuild, it corrected the Sender and Subject, but changed some of the other senders to (I can't remember the exact wording, but something like) "No From address". I ran it again and after a switching to another mailbox and coming back, the From/Sender had updated itself correctly.

Thank you for the tip!
