Wrong Sender on Email

Hey ChicoChik,

If we understand correctly, the email contents do not match the sender. If that's right, rebuild the mailbox to allow the messages to download from the server again. Here's more information on rebuilding and the steps to take: Rebuild mailboxes in Mail on Mac - Apple Support

1. In the Mail app  on your Mac, select a mailbox in the sidebar.

2. Choose Mailbox > Rebuild.

When you rebuild mailboxes for IMAP or Exchange accounts, messages and attachments stored on your computer are discarded, and then downloaded again from the mail server to your Mac. Your mailbox appears empty until the download is complete.

Let us know how it goes.

Take care!

I have noticed this on spam emails: they try to hide their sender address and spoof it to look like someone else, but then I find a completely "reply to" address. If that is what it is, just delete it.
