A Catch-all for email, usually refers to a mailbox
on a domain that will “catch all” of the emails addressed to the domain
that do not exist in the mail server. Configuring a catch-all address
can help avoid losing emails due to misspelling.
For example: if jamee@urdomain.com is configured to be the catch-all email address on urdomain.com, then any email sent to an undefined@urdomain.com email address will be forwarded to jamee@urdomain.com instead of being rejected as an Undeliverable message or Unknown User error.
You can only set one catch-all email address per domain. So it’s better to set the Administrator email address as the catch-all.
