Cannot send emails to Hotmail addresses
Good morning.
Recently, when I try to send an email to people with Hotmail addresses, I receive back the following error message:
There was an error while attempting to deliver your message with [Subject: "xxxxxx?"] to @hotmail.com It has been in queue too long, and will not attempt delivery again. The Destination MTA: "52.101.10.0" reported the following reason for not accepting your message: "451 4.7.650 The mail server [92.204.71.230] has been temporarily rate limited due to IP reputation. For e-mail delivery information, see https://postmaster.live.com (S775) [Name=Protocol Filter Agent][AGT=PFA][MxId=11BB16660512E7F5] [BN2PEPF000044A2.namprd02.prod.outlook.com 2025-05-06T01:00:18.868Z 08DD8B3303D1FF99]\r\n"
(Note that I have blanked out the recipient address and subject line from the above text.)
This only happens with Hotmail recipients. Other emails seem to be going through OK. I have tried it with different email clients, with the same result.
Thanks in advance for any help.
I'm glad to hear that 123Reg have accepted that it's their problem. Well done for that.
It's just emails coming through the 123Reg mail server that will be having this problems so you should not have any issue with emails sent from your Gmail account.
However there may be other email services that also see the 123Reg mail server as suspicious in the same way that Hotmail does, So it may be that some of your contacts are finding your private domain emails appearing in their spam folder or possibly rejected in the same way that Hotmail has been doing.
I certainly hope the problem gets fixed soon.
