Our team has received further feedback from Spamhaus earlier this morning. The listings were caused by an end user emailing a spamtrap/honeypot operated by Spamhaus.

The honeypot domain is a typosquat of a well known brand and the emails sent were not malicious traffic.

We have reached out to the MSP so they can advise their end user of the mistake/typo.
