I have installed exim4 and enabled sasl for authorisation according to the supplied docs, but I don't know how to get the server to authorise. If I allow relaying from all hosts, then I end up with an open relay. If I disable relaying, then there's no option to authorise. I'm sure this is a simple thing to enable, but I can't find the answer anywhere. Thank you for your help. -- Take care, eh. Chris
