* without authentication use port 25 and mynetworks
* if a client is using submission it is good practice to have a user in the logs
mynetworks should be genrally used with care and only for specific
address instead whole networks with sooner or later potentially
infected clients which can be banned if using auth even if the
malware leaks auth data and abuse it from outside
