When reporting spam emails, it is critical that you send us the email headers. Please do not forward the spam email. Forwarding the email will remove the original headers.
Email Client Users (Windows Mail, Outlook, Thunderbird, etc.)
If an email is unable to be delivered to a Comcast.net email address, it's possible the sender's email provider is blocking your address as an antispam precaution for Comcast customers.
The sender should receive an error message containing a link to a FAQ with valuable information regarding the issue and steps necessary to request removal.
Email administrators can submit the blocked IP address to the Comcast Security Assurance department to determine if the IP address is eligible for removal by completing the Blocked Provider Request Form. Requests submitted through this form are reviewed on a 24x7 basis.
When reporting phishing emails, it is critical that you send us the email headers. Please do not forward the phishing email. Forwarding the email will remove the original headers.
Once you have copied the full message headers from the spam message, paste the header and the message into an email and send it to firstname.lastname@example.org with the subject line "Phishing email." We encourage you to download the Xfinity toolbar which contains anti-phishing technology to help you avoid phishing attacks in the future.
You can protect your email accounts from hackers and other threats. Constant Guard from Xfinity makes it easy, no matter what email program you use, including webmail.
Did you know hackers can use your computer to send spam without your knowledge? You can help deter hackers and ensure your email is delivered by following the steps outlined below.
To help protect your computer, please visit our Xfinity Connect help page for instructions on how to securely configure your email client program. In accordance with industry recommendations, Comcast recommends the sending of email on port 587 with authentication or port 465 with authentication over SSL as secure alternates to port 25, which is the default for many older email clients. If you are configured to use a server other than smtp.comcast.net, please contact your mail provider for alternate secure port settings.
If you are a webmail user and use a browser to access your email, you don't need to do anything. However, it is always important to check for and remove any possible viruses from your computer. This can be done by using Norton™ Security Suite for PC (Mac users click here) available from Comcast or by using other popular antivirus solutions that are widely available. Norton™ Security Suite is included at no additional cost with your Xfinity Internet service.
Firewall logs should be sent to the Internet Service Provider who controls the network associated with the IP address attempting to connect to your computer.
