All of the lists we host that have unmoderated posting for even
some subscribers require the moderator to approve subscribers
before they are added. One of the things some of our list owners
have done is ask people to provide their direct ISP address if
it is different than the one they want to be subscribed under.
They send a test message out to that second address to make
sure it is a valid one.
One list owner created a nifty script that checks to see if
that address is any of a list of about 100 of the more common
ISPs. If so, the new subscriber gets an email at that ISP
address they have to hit reply to and the address they want
to be subscribed under is then added to the list. If the
domain is not on this list, the script checks the message
headers for the response and if the domain in the message
headers match the return address, again it is added. Anything
not processed automatically gets logged for the list owner
to look at.
