Email blocked from client's servers?

We are having difficulty emailing a trusted vendor. All of our emails, with or without attachments, are bouncing back. There is no helpful error message, but this is what it says in the bounceback:

This message was created automatically by mail delivery software.
A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed:

[email protected]
SMTP error from remote mail server after initial connection:
host mx2.ipg.iphmx.com [68.232.135.202]: 554 esa4.ipg.iphmx.com


Can you help us figure out what the problem is? Our domain is mirus-group.com

Thank you,
Carl Huber

Hello Finneganm, We do apologize for the blacklisting - it's not something we can always control (check out this article for more info: My Email is being listed as spam, what can I do?). If a problem occurs on a shared server, we do not always know WHERE the problem is occurring from, so we need more info. In this case, we are given a source, but we don't have the full information in order to attempt a de-listing if the server is blacklisted. We need the FULL bounce for information on what's happening. We can't fix something when someone is refusing email from us and we have no idea WHY it's happening. It's not always a straightforward answer. The bounce also typically gives us the information we need for communicating with the administrator of the receiving server. If you get blacklisted, make sure that we have a full copy of the bounce email and we can act on it immediately. If you have any further questions, please contact technical support available 24 hours a day / 7 days a week. Regards, Arnel C. Community Support

Hello carlhuber, 554 error messages are fairly general. They are permanent errors, which is why all emails you send to the address are failing. We have an article explaining the nature of the 554 error here: Email error 554 It is posslbe that the recipient server has your server in a blacklist. Here is an article on why this can happen: Why do mail servers get blacklisted We tested the connection to the recipient server found via the email logs and it is not allowing any contact from your server. You will want to check with the recipient via alternative means and see why their server is not allowing any connection. Perhaps there is something we can fix from our end, but we would need to know what the reason is for their connection refusal. Best Regards, Scott M
