Relaying mail means that a host can send mail through your server without restriction. If the host is a local host (ie. under your control), this may be a good thing - as it means they can send mail to anyone they choose. If the host is not a local host (ie. is not under your control), this is likely a bad thing - it's one of the means that spammers use to send out their email. However, it is not necessary for local users' IP addresses to be listed in smtprelay.tab, as their mail clients can usually provide authentication to the server (ie. they set their mailbox user name and password in their mail clients, and tell it to authenticate when sending mail as well as when receiving mail). The only time it's really necessary to list addresses in smtprelay.tab is for local host machines which are not capable of authenticating when sending mail - the most common example is a web server that has to generate emails (such as order confirmations). Web pages typically aren't set up to authenticate to your mail server when sending their emails. - To unsubscribe from this list: send the line "unsubscribe xmail" in the body of a message to [EMAIL PROTECTED] For general help: send the line "help" in the body of a message to [EMAIL PROTECTED]
