spam freeware thoughts for 12.31.1969
You should not use an autoresponder for any purpose unless absolutely necessary, because these can result in unwanted problems for those whose e-mail addresses have been, stolen by spammers. Blacklisting is pretty ineffective at catching spam since it depends upon the from-address given by the spammer. The spammers seldom re-use these forged or stolen addresses, so adding them to a blacklist could be a big waste of time. Challenge-response filters may seem to work for their users, but they are a nuisance to almost everyone else (with the exception of the spammer, who suffers no more than to lose a delivery or two). Domain Name System Block Lists (DNSBL) are commercial lists of networks that either allow spammers to use their systems to send spam, or have not taken action to prevent spammers from abusing their systems. Probe messages are evidence of a dictionary attack (or "directory harvest attack" or "mx probe") in which the spammer sends probe messages to a large number of e-mail addresses (some of which may be guesses) and prunes out those that are rejected by the mx. Reporting spam websites usually requires you to find their authoritative addresses (the IP address returned by an authoritative name server for a given host name or alias), since spammers can use various tricks to confuse matters. Good isps have an aup to discourage abuse of their network and the internet by spammers.
