If they are created outside -email system, they should not be accepted.
If they are generated inside the system, or coming from a trusted system

virus can collect the saved password and send spam using your server as

One of the checks enabled by default in CHKUSER tries to reject fake
senders, so if the domain declared in the address does not have an MX

DNS MX entry?
