I have my domain name registered with a company and use emaill addresses that use my domain name. I have just changed my websitebuilder using iWeb and pointing my domain name at web.mac.com. Now my email addresses that use my domain name don't work anymore. The company who I have registered the domain with say they can't help as I am pointing my domain at web.mac.com and they would need to sort it out. Any ideas? I still have the incoming server registered as pop.1and1.co.uk which is my domain registrar and the one the email worked with until I changed it to iWeb. Any ideas?
