Suspect email

I keep getting emails - no name - no subject - no message - 01/01/70. I have several email addresses. It appears in my " all messages" box but when I search each individual email address, it doesn't show in any and when I go back to "all messages" it disappears. It will then come back later.

I have just had trouble sending an email, I tried to delete it but my iPad wouldn't let me. I turned off the iPad, then when I put it back on the email deleted and the suspect email had gone.

Is this some kind of bug and how do I deal with it please?

Is the weird email on your mac or on your ipad? If it's on your ipad this thread needs moved to the ipad forum. The only thing I can figure is to close out/reboot and open the mail app again.

Many thanks. I'm new to this and have obviously chosen the wrong forum. I have rebooted and the emails have disappeared.

moved to appropriate forum
