Report Online Harassment
If you feel you are in immediate danger

If you feel you are not in immediate danger
Please document the incident by collecting information that can support an investigation.
- Emails illustrating the harassment, including the email headers.
- Time-stamped screenshots and URLs that display the harassment.
If you believe we can assist in your harassment investigation, send an email to firstname.lastname@example.org with the subject line "Harassment Investigation" and attach all evidence you can provide us to support in the investigation.

How to unblock an email address
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 Xfinity 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 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.

Protect Your Email
You can help protect your email accounts from hackers and other threats.
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.
Mail Client Users
Outlook, Windows Mail, MacMail, etc.
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.
Comcast.net, Gmail.com, Outlook.com, etc.
If you are a webmail user and use a browser to access your email, you don't need to do anything.
Report Firewall Intrusion Attempts
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.
If the IP address resides on the Comcast network
- Cut and paste the firewall logs (including the offending Comcast IP address) into an email and send it to firstname.lastname@example.org. Include the words "Firewall Investigation" in the subject line.
- Do not send the firewall logs as an attachment. Emails sent with an attachment cannot be processed.
If the IP address does not reside on the Comcast network
- Send the firewall logs to the abuse email address of the Internet Service Provider responsible for the IP address.
- If you need help determining the Internet Service Provider responsible for the IP address in question, visit www.arin.net. Entering the IP address will return the information of the responsible party.
