Mediacom being blacklisted?

Anyone trying to blacklist Comcast?  See article below.  I have mediacom at home but don’t use their mail accounts.  Don’t even know if I got one when I signed up. My comments:

Sounds like a good reason to ditch their mail servers all together and use a 3rd party like gmail or yahoo.  The problem might be cyclical as the spam seems to come in waves, but they will likely continue to have issues.

It’s one thing for them to have their mail servers slowed due to dealing with all the spam coming in, but I found something else really interesting.

They are saying that they are blacklisted by other ISPs or mail servers.  That means that either other organisations are blacklisting them as a whole IP block (the customers themselves) OR blacklisting the emails they send from THEIR servers..

What that means is this:

The other entities would blacklist anything coming from any mediacom customer IP because there are so many compromised computers on mediacom.  Which is true.  There are lots of compromised ppl on mediacom or any major broadband provider.  No doubt some of those compromised computers have spam bots installed.

But, if they are blacklisting any mail sent FROM a mediacom mail server, that means they have a reason to believe that compromised people are using MEDIACOM SERVERS to SEND SPAM.  How can that be?  Wouldn’t any ISP shut down a customer who tries to send out 100k emails a day from the ISP smtp server?  Come on!

If someone is (either knowingly or not knowingly) USING a mediacom mail server to SEND OUT spam, that’s nuts.  But it would explain why they are so slow, LOL.

My guess is that there is a large amount of compromised spambot customers and some people have blacklisted mediacom’s whole IP block.  I’ve heard of some people blocking AOL back in the day, but mediacom?  lol.  Must be pretty bad.

Email Migration Update Return to mediacomtoday.com

Overall Status – As of 12/15/2009 18:00 EST

We continue to move forward on our efforts to reduce network congestion on our mail servers. However, the mail traffic coming in and going out of Mediacom continues to be at an elevated volume due to spam.  This continues to impact email delivery and receipt for our customers.

The following is typically what customers will be experiencing:

  • Delay in mail being sent to Mediacom accounts. The average delay for this type of mail ranges from 5 min to 15 min. These averages are based on delivery times from Google mail, Hotmail/MSN, Yahoo and other major sites. Some customers may be experiencing greater delays.
  • Delay in mail being sent out: The outbound mail performance is showing significant delays. The average delay for this type of mail is approx. 1hr; however, some mail will have more significant delays times due to the backlog or because it is being delayed/blocked by a site that has currently blacklisted Mediacom. This may give the impression that emails are being lost but instead they are holding in queue or waiting for sites to allow them through.
  • Customers using webmail may experience “Server appears to be slow” message or also experience locking of said mail page. If this happens please refer our section on “Email FAQ’s” to troubleshoot.

Here are the steps we are taking to combat these issues:

  • We are deploying new security solutions and are actively identifying and shutting down spammers on our own internal network to reduce load.
  • We have made progress in reaching out to our top blocked sites and are starting to see mail being delivered to these previously blocked sites (some of these more slowly than others)
  • We are adding more servers to handle the increased load on the system while upgrading software on existing servers that will allow us to improve processing and tackle spam.

Doing so will require us to stop and start servers. This may further inconvenience mail performance for short periods as we deploy the mentioned solutions. We apologize for these interruptions; however these steps we are taking are all designed to improve the mail performance to normal operating standards. We expect to realize this over the next few days.

We continue to work round the clock to eliminate these issues and deeply regret the inconvenience we have caused to our users.

Email FAQ’s:

  • Will I receive credit for poor email performance? Once Mediacom has completed reinforcing security systems and improving email performance, we will evaluate the overall impact of the migration and take appropriate steps.  Keep in mind that email service is only a portion of the High Speed Internet service that we offer.  We will communicate the course of action in the near future. 
  • Not receiving emails/delay in emails: The average delay for this type of mail ranges from 5 min to 15 min. These averages are based on delivery times from Google mail, Hotmail/MSN, Yahoo and other major sites. Some customers may be experiencing greater delays.
  • Delay in sending email or Mail being returned as blocked by other email providers: The outbound mail performance is showing significant delays. The average delay for this type of mail is approx. 1hr,; however some mail will have significant delays times due to the backlog or because it is being delayed/blocked by a site that has currently blacklisted Mediacom. This may give the impression that emails are being lost but they are actually holding in queue or waiting for sites to allow them through.
  • Webmail Account Hanging or “The server appears to be slow to respond, and may be unavailable” Error. This is due to congestion at the time of the request.
