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.
