Comcast.net Killing email Account

I recently discovered that Comcast.net email account are not getting all of the mail that is sent to them.

concast.netIn January of this year comcast.net has started to meter and REJECT emails to people who have a comcast.net email address.  Bud has a comcast.net email account and he Is not getting all of his emails.

Comcast says:

RL000002 :: Mail to Comcast is queued and I see RL000002 in my email logs. What does this mean?

Comcast has instituted rate limiting on all inbound email traffic. This step was taken to protect our customers and our email system from unwanted spam and malicious attacks. Any systems affected by this rate limit will receive a 4xx message (temp-fail) during the SMTP transaction. This message is designed to instruct the sending server to try again at a later time to deliver its email.

Our rate limiting policy is based on sender reputation and volume metrics, provided by Cloudmark, regardless of the number of domains from that server.

New IP addresses that are expected to send significant amounts of email to Comcast subscribers should start by sending low volumes of mail, increasing as time goes on. As your IP sends more email, its limit will increase daily.

If the rate-limit is impacting your ability to deliver email, shortening your server’s delivery retry interval should resolve the issue.

Translated the  reason why this is happening is one of the following

  1. He is on a distribution list (multiple recipients)
  2. There are more than 3 or 4 links to a web site in the email
  3. He has exceeded the number of emails he is allowed to receive based on the number of emails he got last month.

If you have any people in your address book that has a comcast.net email account the same is occurring to them as well.

The one suggestion that I have is that you tell them this is occurring.  All of the vendors want to charge for the services provided.  If you do not pay for your email account is some way you are at risk of losing connectivity.

Find a provider that gives you the email account for “life” and meets your security and privacy standards to protect t your own information.
