Basically, for a port to be 'open', a program or service has to open the port. When the program/service quits/dies, the port is closed also. If the process is frozen/locked, it may still answer the port, but just not return data or accept data. >I have (by process of elimination) worked out its Norton AV 2003, and im not >that worried about it. But if somebody can explain why its open that would >be great (some technical details would be lovely ;) I have to look this up, but, in order to support non-outlook/outlook-express clients (I think it can be manually told to use the old style setup proxy too), NAV will start up a pop proxy and smtp proxy service, which actually opens the ports. In your mail client, the IP address of your mail server setting is 127.0.0.1, which tells it to use the localhost pop proxy/smtp proxy. When making an outgoing connection to the mail server, your mail client talks to the proxy, which then talks on your client's behalf to the mail server. Basically, your mail client never actually speaks directly to the mail server. This is how it intercepts viruses. In the username box, instead of just your username, you have to put in [EMAIL PROTECTED], because the POP3/SMTP server is set to localhost. So, as long as the POP3/SMTP proxy programs are running via NAV, the ports are open. In 2002, its easy to disable the email checking - its via the options under e-mail scanning.
