To try and eliminate at least part of this discussion, lets go with your position that he's your customer regardless of who he is physically connected to at any given point in time, and that he is using 'pop before smtp' authentication to avoid you running an open relay.
Great, and fine, we agree on this. You still have completely failed to explain WHY this configuartion is not compatible with my stated practice of blocking outbound port 25 for the ip ranges dynamicaly used by dialup users. That is after all the point of this thread: the practice of some network admins of preventing dialup customers from running their own smtp servers behind their dialup connection. When your customer's are roaming, by definition they are not using one of your dialup ports, nor are they using an ip address from your dynamic dialup ip pool. So how can they possibly be effected by this practice? -Alan >| If someone, as in your example, is connected to AOL and is sending a >| message to an MSN address, then at that specific point in time, they >| are not your customer, they are an AOL customer and as such should be >| using AOL's smtp servers, definatly not yours. > >He is my client because I manage his mailbox on my servers and I get paid >for that ! .
