Here is the full error returned by Microsoft: host mx1.hotmail.com[.120] said: 550 SC-001 (COL0-MC4-F28) Unfortunately, messages from 94.23.***** weren't sent.Please contact your Internet service provider since part of their network is on our block list. (in reply to MAIL FROM command) @Stephen Ostermiller yeah, it's unbelievable, the form i found was another one probably the latest version of that, i submitted 4 times but no one submit returned a confirm message :/ like the form was broken unbelievable, billionaire companies not able to build a simple submission form with a confirm message , unbelievable :/I guess they are now big enough to start making everyone crazy, simply by not following the rules.From this 3rd party link, the MX records of your domain are still pointing to Go Daddy. Regards, Balakumaran [email protected], The above email was rejected by the destination server as the email address does not exists.
The recipient's server isn't authoritative for the domain you're sending to. The recipient doesn't have the email address that you're sending to. Some other configuration error on the recipient's end. and they have no problem sending/receiving internally, so the address must be in their system...right?A client recently switched to Exchange Server / Outlook for their email.Since then emails from my company to any email address at their company bounce back from the System Administrator with this error: Your message did not reach some or all of the intended recipients.Any suggestions on what questions to ask or how to fix this would be helpful.I'm using a desktop version of Outlook 2007 and connecting through my ISP. Of course you're not being blocked because the NDR states "recipient rejected", not "sender rejected".
