This issue has been solved. See solution.
A sender from a particular domain tried to send an email to me but recieved a bounce with the following message:
Failure welcome message from "brightmail public ip address", 554 You are not allowed to connect.

They used to be able to send emails to me until last Friday.
All other domain emails are coming in fine.
