Shut down the SMTP server.
The mails that would like to come in from outside should sit in mail
queue on the other end for 5 days while your SMTP is not accessible,
so if you don't need the SMTP for outgoing mails or you can tell your
users you scheduled a time frame for working on server and they're
unable to use the SMTP for approximated xx minutes/hours you're done.
