catch all is an emailaccount that collects all mail that isnīt to a real emailadress on your server.
If someone sends mail to you, and misspell this, like if your emailadress was erik@domain.com, and someone sent mail to eri@domain.com, it will be collected by an account you might call postmaster@domain.com.
Basically, you need to go into control panel for email (if you have something like that on your server), add an email account named for instance postmaster@domain.com, and mark it as CATCH ALL. Then you need to go into setup in admin of GT Mail, and tell GT mail that your CATCH ALL account is postmaster@domain.com
