How can I delete catch all mailbox?
To delete a Catch All mailbox, first switch Catch All OFF.
But, What is this Catch All mailbox option?
Example: your mailbox mailto:email@example.com firstname.lastname@example.org marked as catch all. If someone sends an email to <amailto:email@example.com, firstname.lastname@example.org, which doesn’t exist, this particular message will arrive at webmaster@1800ssl. If no account were marked as catch all, this message would bounce back to the sender with an error notification.
