All emails we send to a specific company are returning this message:
xxx x.x.x Service unavailable; Client host [xxx.xxx.xx.xxx] blocked using Blocklist 1, mail from IP banned; To request removal from this list please forward this message to [email protected].
Up until this week we could send OK. Same thing happens when using Internet Email or web mail (e.g. Hotmail, Just Host etc)
Where do I start?
