Apple Mail for imac

Hello bseabob,

We'd like to clarify some information, so we can assist.

To confirm, are you saying that messages you didn't send are appearing in the Sent folder in Mail on your Mac, or are sent emails appearing in your Inbox unexpectedly? What happens when you try to delete those emails? Do you receive an error message of some kind?

The above information will help us plan how to proceed.

This link has some information on managing and deleting emails in Mail, which may help: Delete emails in Mail on Mac

Delete emails in Mail on Mac

You can delete email messages that you don’t need anymore to help keep your mailboxes manageable, and to free up storage space on your Mac or on the mail server. Deleted messages are available until they’re permanently erased.

Delete an email

1. In the Mail app  on your Mac, select a message.

2. Click the Delete button  in the Mail toolbar or move the pointer over the message’s header, then click the Delete button that appears.

Tip: To prevent the next message in the list from being automatically selected (and marked as read), press and hold the Option key when you delete the message.

If you set the “Move discarded messages” option to Trash in Viewing settings in Mail, you can delete a message by swiping left on the trackpad with two fingers or by moving the pointer over a Mail notification, then clicking Delete (or the Trash icon).

Thanks!
