@thisisrk. Thanks for trying the site. We can look more into it. Can you provide the device you mainly use and if you use any 3rd party clients. If you use other clients, the bounce happens on those as well?

We provide mailing services just like Mailgun, though we are not expert in this. Just a beginning I must say. We have our servers equipped with PowerMTA and PHP Mailer.

@thisisrk Did you find anything that @BruceW was referring to? You have Comcast business internet service, correct?

I'm not Comcast so I can only work with the information you've posted. And, as stated above, if you view the raw source of the bounce email you should find additional information explaining what the problem is. That single line you've posted isn't helpful in understanding what's going on.

By raw source do you mean the email HTML code? Earlier the mailing server was working fine. But after that it started to receive this error. 
And by raw source do you mean the HTML Code?

By raw source do you mean the email HTML code? ...

Bounce messages typically consist of two or three plain text sections followed perhaps by a copy of the bounced message. Additional information is usually found in those plain text attachment sections, accessed via a "View Source" or "Message Source" option. For an example of the kind of thing I'm looking for, see https://forums.xfinity.com/conversations/email/new-limit-on-email-exchanges-solved/6328b97a48c60d55e60521f7?commentId=6328f7c02ff2c66589fffc40.

For more on "View Source" see https://www.google.com/search?q="email+View+Source".

The IP (89.248.104.251) in the transcript was observed sending what appears to be spam and phishing of various types.

In past too customers have done spamming, for that we suspend accounts on basis of blacklist databases search. But this error doesn't provide any such information. Isn't the server be blacklisted on basis of comcast error codes which resemble to #BL00001 or something like that. Or Is this a soft blacklist?

@XfinityBrandon​ That's very supportive that you would like to see thorough it. So what steps are next? Could you help me in evaluating what kind of blacklist is this, as there is no sufficient information available to me.
