Email gone bad

My mail account with Comcast showed the same behavior as yours. I did see a post with a solution. Do this in Mail App, hover cursor over favorites at top of left side panel, click on +sign, then select all trash. This puts trash in favorites list and seems to work, at least it has worked for a couple of days for me.

Hi there, Canandaigua_7021.

It appears that you're having a problem with the Mail application on your Mac. When you delete a message, it doesn't go to the Trash folder, and the Junk folder is missing. We understand how important emails is, and we're glad to help with this.

Delete emails in Mail on Mac - Apple Support -- With the Mail app open, choose Mail > Preferences from the menu bar, then click Accounts. Select an account, then choose Mailbox Behaviors and make sure that the Trash Mailbox is set to Deleted Messages.

Change Junk Mail preferences in Mail on Mac - Apple Support -- Next, select the "Junk Mail” tab on the same screen and make sure that "Enable junk mail filtering" is selected.

If you’re still having a problem with either issue, quit the Mail application using Mail > Quit Mail, then restart your Mac. See if the Mail app is behaving as it should now.

Feel free to get back to us with any questions or problems you may have.

Take care.

In Mail Preferences, Accounts, select the account and then look at the Mailbox Behaviors tab.

You can pick which folder is used for Trash.

Look in the location of the folder that is set for Trash for that account.

Set it to where you want trash emails to go for that account.

There is no option of "selecting" which Trash Mailbox.

Yes, there is.

POP account?

I haven’t used one in too long too know how it works.

You are welcome! Some other user had discovered this secret. I had tried everything I could think of short of calling Comcast.
