How “catch-all” option work?
The catch-all option is a pretty useful function, but quite underrated
In few easy word, it allows addressing emails to a specific email account in case of the destination email is wrong.
Obviously, it works on a single domain.
You have only to set the account you want to be the catch-all account (e.g.: email@example.com)
for being the catch-all account.
All the emails sent to <account>@mydomain.com in case of the <account> is missing will be delivered to firstname.lastname@example.org.
