Catch-all (Mail)
From Wikipedia, the free encyclopedia
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 jondoe@xyz.com is configured to be the catch-all email address on xyz.com, then any email sent to an undefined @xyz.com email address will be forwarded to jondoe@xyz.com instead of being rejected as an Undeliverable message or Unknown User error.
Catch-all addresses are commonly known as spam magnets[1], in spite of their usefulness to allow you to receive e-mail from people who can't remember your email address or mistypes it. As such, it is a general good practice avoiding them and discouraging their use.
