Subject: Re: Spam Control Considered Harmful Yes, that is precisely what we do. However, what I pointed out was that if the ISP they dial into blocked all traffic to port 25 elsewhere, as was suggested, then they wouldn't be able to get to their virtual host residing here to send out mail.
One easy way around this problem is to forge closer relationships with the ISPs your customers use for connectivity. One of the easiest ways I can think of doing this would be to become a member of a roaming service like iPass and through that become a virtual ISP where you effectively purchase connectivity time from dial-up providers and resell it to your users. Then since you're providing the authentication of your users you can also provide in their profile a list of SMTP relay hosts that they should be permitted to connect to. Your users would then be free to choose to dial into any iPass dial-up provider anywhere in the world at any time without even needing an account opened with the particular dial-up provider they happen to be able to get through to today. -- Greg A.
