You have been identified for sending spam into the Comcast domain.
Our filters have determined that email from your mail server has been sent in patterns which are characteristic of spam.  In an effort to protect subscribers, your mail server has been blocked from sending email to the Comcast network. 

I was unaware I/my email provider was sending spam.
In this case, you are advised to make sure that your system is secure and free from viruses or vulnerabilities that would allow your PC to be used to send mail without your knowledge. 

If you send mail through an Internet Service or email provider or have mail forwarded through a hosting / mail forwarding provider, please contact them and report this issue. Comcast recommends the provider review their outbound email policies and take immediate action to reduce the amount of spam being sent to the Comcast domain.  Unless your mail provider takes these important steps, your mail may continue to get blocked by Comcast.

I am confident that my mail server is secure and that we follow good email practices.
There is a possibility that your mail could have been misidentified as spam. If this is the case then you must present a copy of the email to Symantec for further investigation.
Ask your administrator to identify the emails recently delivered to the Comcast network to determine which messages were potentially considered spam, before the block was applied.  Ask your mail administrator to send an exact copy of the messages (body and header) to Symantec as outlined here.
