Microsoft blacklisted TSO Host's email IPs from Hotmail, Outlook inboxes and no one seems to care

Apart from the poor sods paying for the service, that is

Microsoft has blacklisted Brit hosting outfit TSO Host's bulk email domain, meaning anyone trying to send large quantities of mail over its infrastructure cannot deliver it to an Outlook or Hotmail address.

Irate resellers got in touch with The Reg to complain that their own customers were moaning that emails sent to any Microsoft domain were bouncing.

Those resellers were using TSO Host's infrastructure for their operations – including the hosting firm's dedicated bulk IP.

"Rather a lot of our clients have mailboxes with TSO/Paragon," reflected one.

"Apparently TSO's 'senior team' have requested the removal a while ago but Microsoft aren't interested."
