Very true. I was simply explaining why some administrators would like the ability to change the banner. This can be useful because most prying eyes are just kids with a trick they picked up in school. Skillful hackers can hack a system no matter what an admin does to prevent it, short of disconnecting all the server cables and placing the server in the vault at the local bank ... and it's still not completely safe!

If you really want to hack a system and have the skills, you don't need an full featured smtp banner to get you information. - 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] - 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]
