Electronic mail is a means of transacting information between individuals using electronic devices, such as computers and email servers. Initially, electronic mail was restricted to a small number of users on the same computer, with a corresponding limited capacity for sending. Later, some systems even supported a kind of chat, where sender and recipient had to be in the same physical location to interact. However, most email systems are set up today so that a user can send an email to any email address on the Internet. The sender’s email address and the recipient’s are stored on separate machines, and this separation helps the system to scale Email1and1 without consuming much processing power.
Today, there are several ways of protecting emails that contain sensitive information. The most common is to encrypt the recipient’s and sender’s emails, and use email security software that automatically encrypts emails before transmission. This ensures that the email will not appear as spam to the recipient and that it can be forwarded to others. In addition, an advanced spam filter can detect and discard messages that are sent to known email addresses.
Some organizations also use “CC” recipient fields, which are used to indicate to other parties that the message should not be passed to another party. For example, a business might set up a separate account for receipt and delivery of checks and bills. These accounts might include a separate bcc recipient field that prevents other people from taking legal action against the business. Similarly, a marketing company might have a separate e-mail list that contains customer contact information, for instance, and use automation tools to remove the need to individually add each contact to a list or prevent the creation of a new email address for each customer.
Automated email service providers such as SpamFighter and POPfile also allow users to configure rules for the handling of electronic mail. This feature allows users to decide what kinds of content should be allowed into the body of the message and to specify various blocking options for particular content. Some programs enable users to set parameters for the amount of time to pass between electronic messages.
One well-known piece of software that is commonly used for spam and email security is the ToMLinson email program. The original version of ToMLinson is designed for the UNIX platform and has been in wide use for several years. However, a recent version of ToMLinson offers a free online demo version. The program was developed by scanning the floors of large companies in order to identify malicious e-mails. The program finds the e-mails from servers that are regularly used for spam. The scanning technology is so good that it is more likely to identify a spam than a legitimate piece of mail.
Another piece of spam protection software, called Carbon Copy Pro, allows users to create virtual credit card numbers that can be used in place of credit card numbers in a fraudulent transaction. Users can specify the number of virtual credit card numbers that will be generated and can choose how many accounts the new credit cards will be applied to. Unlike with ToMLinson, carbon copy restricts the number of email addresses that can be associated with each virtual credit card number. This feature is useful for preventing spammers from sending unsolicited bulk e-mail to recipients.
