What precautions does Comcast take about spam?

With more than 10 million high-speed Internet customers, Comcast takes its responsibility to combat spam very seriously.

Comcast is aware that a careful balance is required to effectively reduce spam while also protecting Internet users' online experiences.

In the last year, Comcast has taken an industry-leading position in spam protection. The company has reduced inbound/outbound spam by more than 70 percent by utilizing a variety of techniques to block spam before it ever reaches customers' email box.

          These include:

• Reputation Services.
  
• Confirmation that the email originates from a reputable source.
  
• Determining if the sender is a known spammer, and block accordingly.
  
• Automated Spam Filtering.
  
• Comcast uses Brightmail, a best-in-class vendor, to filter outbound and inbound spam using the latest tools and software.
  
• In the last year, Comcast has significantly increased its number of Brightmail honeypots, going well beyond typical best-practice measures. (Note: honeypots are email addresses created for the sole purpose of catching spammers).
  
  Port 25 Blocking:

• Port 25 is conduit on a computer that spammers can take control of and use to send their spam, often without the user ever knowing his/her computer has been "hijacked". Comcast works with customers to block access to Port 25 and protect their PCs.
  
•  Comcast recommends that customers establish a more secure email configuration on their PC - Port 587 . Comcast has made it easy by creating a one-click fix that automatically configures computers to this safer PC configuration. Spam Blocking (Blacklisting)
  
• Spammers are constantly looking for new ways to target customers, often hiding behind legitimate mail hosting and mail forwarding companies without their knowledge. In these situations, Comcast applies a precise, scientific approach to identify key indicators and patterns of spam and then blocks those senders classified as sending excessive amounts of spam.
  
• Comcast's McAfee Internet Security Suite includes McAfee VirusScan, McAfee Personal Firewall Plus, and McAfee Privacy Service (with Parental Controls).
  
• The Comcast Toolbar includes free spyware detection and removal, pop-up blocker, and anti-phishing software.

  Tips to consider when creating an online account:
  
  
• Add numbers to your username.
  
• Choose a password that cannot be quickly identified, avoiding pets' names, mother's maiden names or birth dates that contain both numbers and letters.
  
• Change passwords every few months. Tips to consider when using an online account:
  
• Be careful when sharing name and email address on Web sites, newsgroups, or chat rooms.
  
• Be leery of any Web site requesting too much personal data, such as passwords, social security numbers, credit card numbers and income level.
  
• Immediately delete spam messages, as opposed to replying to the message or entering a Web site to have an email account "removed" from a mailing list.
  
• If you think you've received a fraudulent email, contact your internet service provider immediately. Comcast customers can forward a copy of the email with the full header intact to abuse@comcast.net with the subject line of "phishing email" and it will be investigated immediately.
