Sending to @Comcast addresses

Hello.

I run a small hosting company.  One of my domains for some reasons encountered the following issue.  The customer does not send much E-Mail nor does the server as a whole.

SMTP error from remote mail server after end of data: 451 4.2.0 Throttled

Please advise.

Thank you,
Larry

Hello @user_t3lz51, Thanks so much for taking a moment out of your day to leave a post on our community forum, and we would be happy to help. Do you have a business account with us or are you running these off your residential services?

Hello.

Thank you very much for getting back to me.  It is hard to get in touch with someone regarding this message.  I am a residential Xfinity customer but my servers are based with US Amazon infrastructure.

Sending E-Mail from this one particular platform was never an issue until the last few weeks.  This is legitimate E-Mail going to less than a dozen at a time to @comcast.net addresses.  The individuals that are part of this E-Mail already are aware of the E-Mails coming from my customer but they cannot receive them because of the rate limit currently in place.

Larry

@user_t3lz51, If you could send our team a direct message with your full name, the name listed on the account (if different), and the service address associated with your account, I'd be more than happy to look into this for you. To send a Direct Message, please click on the chat icon in the top-right corner of the screen, next to the bell icon, and then type or select "Xfinity Support" to initiate a direct message.
