smtp;550 Sorry, we do not accept connections from you (Campaign Monitor)

Do tele2.nl operate a email blacklist/blocklist? I am trying to send a friend who has a tele2.nl email account an email via Campaign Monitor (a large, well known mailing list company).

 

Multiple emails, over many months, have been rejected with the following message:

smtp;550 Sorry, we do not accept connections from you

 

The from address and return-path domains are cmail1.com through cmail20.com and the full allow list of domains and IP addresses at https://help.campaignmonitor.com/whitelist-campaign-monitors-addresses

 

I am wondering whether tele2 has mistakeningly added them to a block list?

Hey Paul,

First off; welcome to our Community!

Please send me a private message with the following: 

  • E-mail address and IP-address where you’re mailing from
  • E-mail address and/or IP-address of the one you’re trying to send the mail to

I will send this info to my colleague and he will fix this for you. I’m looking forward to your reply! 😄

Hey Paul,

You’re absolutely welcome! I’ve sent the info to my colleague. He usually fixes this really quick, and I’ll let you know once I get a reply from him. 🙌🏻

Will you also let me know if you’re starting to see that the mails are coming through?

I’d love to hear from you.

Kind regards,

Marciano

🤞🏻 Will let you know. We only do a monthly mailing from Campaign Monitor so it may take a while. Thanks again for your help and responsiveness with this.

Just to say that all this worked and my friend (who is a customer) is now receiving newsletters. Your help really appreciated, especially as I’m a non customer!

I’ve just sent another email and got exactly the same error message again, so something appears to have automatically reset? Any chance we can reopen the ticket?

Hi @paulginsberg!

I want to check if your IP is on the Spamcop Blocking List. You can fill in your IP-address and check this. Can you do that for me? 

Kind regards,
Manouk

 

203.55.21.31 (the IP address of the sender) is not listed in spamcop. I’m happy to send a full set of headers over.

Any update here?

Hey Paul,

I think there was some miscommunication about whether it was solved or not. Please send me this info again and we’ll fix it for you! 

  • E-mail address and IP-address where you’re mailing from
  • E-mail address and/or IP-address of the one you’re trying to send the mail to
  • Date and time of when the e-mail was sent

I look forward to your message. 😊

I was told it was done, having passed those details previously. I will resend those details to you privately right now.
