To be sure spam or viruses can't propagate using your 'internal' workstations, it is recommended to set them to AUTHenticate with the xmail server ! because up to now, no virus or spam or trojans try to auth or it is difficult to implement a 'password' sniffer in a small program like viruses .... So don't put 192.168.xxxxx in smtprelay.tab and set your mail user programs on your internal workstations to do SMTP AUTH !!! This is the best setup for security at server level at this time... (until doing encryption and use public keys infrastructures on all smtp traffic as the new 'basic' and mandatory mail exchange solution anywhere on internet ....)
