Anti-spam filters can help a business make sure it only gets the e-mails it needs. An individual can also use these filters to figure out which e-mails simply want to waste their time and which might actually be of interest. A few powerful tools exist that allow a computer user to make sure to cut back on the unwanted intrusions into his time. Some of the best filters do not require a person to spend money on them at all.
The anti-spam filter with the widest variety of features does require a person to engage in a small initial investment. The PC Tools Internet security suite allows a person to block unwanted e-mails or place them into a spam filter. It also detects malware and viruses in an e-mail before a person opens an attachment.
A supporter of open source software or a user of Thunderbird may want a personal program that he can integrate with his favored software more easily. Mailwasher provides many of the same features of the PC Tools Internet Security’s sweets mail program and does not require a subscription. Because it does not require a subscription, it does not have an expiration date.
Spamitback is an anti-spam program designed to annoy the spammers just as much as they annoy the user. The user sets this program up to deliver a message automatically to the spammer, and allows the user the option of receiving the messages or deleting them, just as the other programs on this list do.
