Error message "550 5.7.1 Connection refused - blocked by Validity"

Force9 is well into the migration programme, however if you have a hosted domain name with the account, then you will not yet be on the schedule.

If your portal profile details are correct, you have been migrated.

Thanks.

I'm still not receiving any emails on my username@trutta.f9.co.uk so I don't know whether I have received an email from Greenby or not. The  last sync date was December 3rd.

I can log into the Plusnet Portal successfully but not to webmail on either the Plusnet or Greenby sites. On the Greenby site I have tried using my full email address and the password I use to access  the Plusnet Portal but without success.

I have tried contacting the Plusnet help but when humans tried to contact me I have been out or my phone has been somewhere else. I will try again later this afternoon.

Hello,

I’m unable to send emails from my Totalise account to Hotmail/Outlook addresses. The bounce message says:

550 5.7.1 Unfortunately, messages from [IP address] weren't sent. Please contact your Internet service provider since part of their network is on our block list (S3150).
More info: http://mail.live.com/mail/troubleshooting.aspx#errors

Microsoft’s IP Delist Portal confirms my IP isn’t blocked, so it seems part of the Plusnet/Totalise network is on Microsoft’s block list. Can Plusnet investigate and request removal from Microsoft?

Can you help me please and get this working again?

Simon...
