  • Ticket #421 – Description

    initial v5  
    11To help cut down on outgoing spam, we should require that mail sent directly through Scripts carry a matching `@scripts.mit.edu` address or an address at a matching Scripts vhost.  After all, if you want to send mail from `@mit.edu`, `@gmail.com`, etc., you should be sending it through `outgoing.mit.edu`, `smtp.gmail.com`, etc.—a mismatch here would be an SPF violation anyway.
