It is a shame that you forbid network access. Instead you could avoid the problem you had by blocking outbound smtp port 25 access. That is what most networks are doing these days and would prevent your problem from recurring while still providing normal network connectivity. Random clients do *not* need outbound smtp port 25 access. Most vendors will use a company VPN for their network access and others may use TLS for just mail access. For those misguided souls still trying to send smtp on port 25 from random locations can simply be blocked when away from their home base. This should encourage them to improve their configuration.
