What are some of these new and enhanced junk e-mail filter features?
BB Media junk e-mail filter system is made up of a combination of open-source software and custom-built technologies that, in testing, has shown to dramatically decrease the amount of junk e-mail people receive (up to a 90% reduction if all features are enabled).
Here are some of the features of our newly improved junk e-mail filter system:
- Separate server configuration -- e-mail is filtered before it even reaches your account server!
- SpamAssassin 3.0 -- a powerful junk e-mail filter
- Greylisting -- a new approach to decreasing the amount of junk e-mails
- E-Mail Virus Scanning -- utilizing a sophisticated e-mail virus scanner, Clam AntiVirus
- Spamhaus DNSBL -- a real-time "blacklist" to block e-mail addresses that send junk e-mails and reject junk e-mail messages from these addresses
What is "greylisting"?
Greylisting is the name of a method that is used to reduce the delivery of junk e-mail but allow legitimate e-mail messages to be delivered.
Greylisting looks at the IP address of the sender and the recipient address. If the system does not recognize this information, then it will temporarily reject the e-mail. All legitimate e-mail systems will attempt to resend the e-mail at a later time, and the e-mail will go through.
Most applications that send junk e-mail just send junk e-mail messages once and do not attempt to resend them. These junk e-mail applications use the "fire-and-forget" method, which means that if the junk e-mailer was unsuccessful at sending junk e-mail to a particular e-mail address, the application will not try to resend that e-mail message.
Greylisting does not delete legitimate e-mail messages. All legitimate e-mails will go through using greylisting. The only potential effect greylisting may have for BB Media customers is a slight delay in the delivery of legitimate e-mail messages.
However, these delays can be avoided by adding e-mail addresses to your "Accepted Addresses" list. Any e-mail address in your "Accepted Addresses" list will not be subjected to greylisting. In addition, if you do experience a delay with a certain e-mail address, you usually will not experience that delay again over the next 30-day period.
What is a DNSBL?
DNSBL stands for Domain Name System-based Blackhole List. A DNSBL lists IP addresses, usually those that have been observed by the list operator to send junk e-mails, that are used by applications to decrease the delivery of junk e-mails.
These lists are developed by third-party entities and are not supported or maintained by BB Media. However, we give you the option of using particular DNSBLs, which may reduce the amount of junk e-mails you receive.
BB Media allows you to enable SpamAssassin's DNSBLs that SpamAssassin uses for junk e-mail scoring. SpamAssassin uses a scoring system to determine what e-mail is junk e-mail and which e-mail messages are legitimate.
Our new junk e-mail filtering system also allows you to use the DNSBL called Spamhaus SBL-XBL (see spamhaus.org for more information) to reject junk e-mail messages and to block those addresses that send junk e-mail.
Will these new junk e-mail filter features cost me anything?
These new features will not cost you anything. Junk e-mail filtering is a free service to help protect our customers from unwanted junk e-mail and viruses.
What if I don't want to use certain junk e-mail filter features?
You do not have to take advantage of any of these new features. Just email if this is the case.
Now that BB Media is scanning my e-mail for viruses, do I need to use any other anti-virus software?
Yes. We strongly recommend that you use other anti-virus software to protect you from viruses, spyware, and other potentially harmful applications. BB Media uses the open-source software, Clam AntiVirus, to scan e-mails for viruses. You can obtain viruses in many different ways and need to use other anti-virus software to protect yourself from viruses.
BB Media is not responsible for the harm computer viruses may do to our customers' systems. We are also not responsible for the effectiveness of any third-party anti-virus software.
What if I have e-mail addresses in my "Accepted Addresses" list or my "Addresses to Mark as 'Junk'" list?
Any e-mail address you currently have in your "Accepted Addresses" list, also called a "whitelist," exempts e-mail from certain e-mail addresses from being junk filtered. These "whitelisted" e-mail addresses will automatically bypass greylisting, SpamAssassin, and all other junk filtering features. However, even e-mail sent from whitelisted e-mail addresses will be scanned for viruses.
BB Media' junk e-mail filter system will automatically reject any e-mail messages sent from e-mail addresses on your "Addresses to Mark as 'Junk'" list, which is also known as a "blacklist."
If you have an e-mail address on both lists, our system will treat that e-mail address as if it was not on either list, thereby ensuring e-mail sent from those addresses will be processed through our junk e-mail filtering system.
