Damn, you're right...

Well, if the problem gets this serious, then there is a need for serious 
measures. You could always quit using email altogether, but I don't find 
this as a solution, but resignment.

A solution (albeit laborous one) would be to every day accept only mails 
adressed to:
yyyymmdd at yourdomain.com, where yyyymmdd is the current date (and maybe 
accept also the previous and next dates too, because of time zone 
differences).

If you still get spam, the you can require the date to be followed by 
accepted name: you have a friend called John, and today he must use 
address 20040417john at yourdomain.com.

Easier solution would be to require something in the subject or body of 
the email - senders email address would be good: john at hisdomain.com must 
include 'john at hisdomain.com' in the subject line. Or give your friends 
each a password that they must have in the first line of the message 
body. This is actually very good option, as it can be used even without 
your own domain name.

How do these sound to you?
