I need to configure an SMTP server to accept any email to any address that might happen to reach it on port 25 and deliver it to a local mailbox (i.e. a spam sinkhole)
The default supported MTA on my O/S is Postfix, of which I have no experience. I used to do a lot of Sendmail and Exim, but that was years ago.
Can this be done with Postfix?
