Comcast Mail Server Rejects Legitimate Email Messages As Spam

Comcast Mail Server Rejects Legitimate Email Messages As Spam

I am growing increasingly frustrated.  Whenever I attempt to send an email message to either of two addressees, the Comcast mail server rejects the message as spam.  Here is a typical result:

 

===========

===========

 

The addressee is my best friend from our college days and he has *not* marked any of my messages as spam, or asked his ISP to block messages from me.

 

This has been going on for more than a month now, and a few weeks ago, it started happening with another email addressee.

 

I called Comcast Technical Support to request assistance.  A ticket number was issued.

 

A day or so later, I got a message as follows:

 

********

 

From: XFINITY My Account <online.communications@alerts.comcast.net>
Date: Thu, 15 Sep 2016 19:48:29 -0400
To: "[my email address]" <[my email address]@comcast.net>
Subject: Test Email from Comcast Team
Reply-To: online.communications@alerts.comcast.net

 

Hello,

Good news! This message confirms that you can now successfully send and receive email via Comcast mail servers.

You can learn more about email features and manage your preferences by visiting Xfinity Overview.

Sincerely,
XFINITY® Team

Please do not reply to this email, it is not monitored. If you'd like to contact us, please visit our

**********

 

The problem has not been resolved, and attempts to use the URL for a web chat with a Comcast Service Rep just put me into an endless loop that never results in being able to reach someone.

 

Does anyone know how I can rectify this situation?  Thanks in advance for any suggestions.

JJMcVeigh-

 

The system rejecting the message is actually the optonline.net server.   The reporting MTA (the comcast one) is the one that tried to hand the message to optonline.  When optonline rejected it, the comcast server composed the rejection and sent it to you.

 

I don't see anything unusual logged about your outbound messages.   Can you try sending different content?  Is there a URL that you're including?  We don't have any control over optonline's filters, but your friend might be ablt to get the support folks at that end to look into it.

 

Hope this helps,

Thanks to you and the others for the replies.  The content does not seem to affect the behavior... plain text only, plain text and URLs, URLs only, plain text and attached images... all trigger the same result.

 

I am curious how you can tell that it is an Optonline mail server that it balking at the messages.  The response is near-instantanteous, and all of the servers mentioned in the rejection message are Comcast servers.

 

 

 

Yo

 


 

Well, it's along the lines of what I mentioned before.  While you don't see the explicit "optonline rejected this server", a careful reading of the rejection text tells us:

 

the reporting mta (the resqmta server)- the one that said it can't send it to the next hop 

the received from mta (the resomta server) - the one that handed it off to the reporting mta 

 

Also the specific text: "554 5.7.1 Spam detected by content scanner. Message rejected." isn't a rejection message used by Comcast.

 

Hope this helps,

The only thing I can suggest is that you call Comcast security to see why your recipient's email domain is causing a problem.  There are a number of reasons why this could be happening.

Thank you very much for the explanation.  I will ask my friend to take up the matter with Optonline.

When Comcast composes that DSN, couldn't it include an indication as to which system rejected the message? A single line like "Message rejected by <servername> would be extremely helpful and a huge improvement over the "mystery" DSNs we get now.

We customers don't have access to any but a few of the "rejection messages used by Comcast", so, again, it would be really helpful if the DSNs were a bit less cryptic.
