Some interesting development has happened over the last 3 days. One of my clients, the one who's email is with Mweb phoned me ons Monday and said their email isn't working. We had to change the MX records, as I suspect Mweb has changed something on their side. So I change MX records as requested.

Today, their email is still not working and Mweb blames us. Interesting though, since the MX records points to corpmx.worldonline.co.za - I can't verify if this is correct though since the Mweb techs can't tell me if, and where this client's email is hosted.
