spmug612 Daily Fight Against Spam Q. I made the mistake of filling out a survey online, and ever since I have spent 10 to 15 minutes a day adding addresses to my "block senders" list. Is there any way I can block all of these at once and report them to some entity? A. Fighting spam can be a daily battle for many people, especially because those who send junk mail are constantly finding new methods of delivering unsolicited messages. There are several approaches to cleaning up your mailbox, including buying a third-party spam-filter program, which is often included now in many Internet security software suites. Other defenses against in-box invasion include using a mail program with a built-in junk-mail filter or subscribing to a service that culls spam from your legitimate messages. Using a spam-screening service may require you to get a new e-mail address - or ask your correspondents to verify their identities by quickly filling out an online form before their messages can get through - but this approach can almost eliminate junk mail because any unapproved sender is blocked. ChoiceMail (www.digiportal.com/choicemail.html) is one company that offers this sort of permission-based e-mail, and there are links and reviews to several similar mail-screening systems at spamlinks.net/filter-cr.htm. Using a separate spam filter with or within your mail program can trap a lot of unsolicited messages in a Junk Mail box, but may require some fine-tuning on your part as the program learns what you consider spam. These types of spam filters tag suspected junk mail and can usually reroute spam into its own separate mailbox for easy mass deletion. If you find a piece of legitimate mail has been caught in the spam filter (or a piece of junk has wiggled through), you typically just have to select the message and tag it yourself as wanted or unwanted so the filter remembers what to do the next time it encounters a similar message. As for reporting spam, the Federal Trade Commission has advice for consumers at www.ftc.gov/bcp/conline/pubs/online/inbox.htm.
