You could try a pop before smtp program that you use with qmail. It
will in real time add and remove (based on a time limit) ip's to the
relay control file for people who have pop accounts your system. The
way it works is a person would check their mail which involves their
mail client contacting the server's pop daemon. The pop before smtp
program would let the user get verified and logged in then record their
IP address to the relay file so that when they go to send mail via smtp
it will allow his ip address. I have it working with Vpopmail (which is
a virtual mail add-on to qmail but also has the above feature) and it
works fine. Another program which doesn't do virtual mail it just does
the pop before smtp is by Bruce Guenter and can be downloaded and etc
from em.ca/~bruceg/relay-ctrl/ . I haven't personally tried it but I
have heard it mentioned many times here in the list.
