This is what I don't understand. If his originating IP is what trigger this
rule, how can changing his SMTP relay to the ISP's solve anything? He can use
any SMTP server, but the originating IP will remain the same, right?

I think I'm misunderstood. Right now, he is using *my* mail server, which is
outside his ISP, to relay his mail. My mail server (edu domain) is configured
to use SMTP authentication. This still triggers the rule, which baffles me,
since the (newly configured) mail server is not in RBL, nor it's an open
relays.
So you may be right that telling him to use his ISP's mail server instead will
fix the problem, but I still don't understand why. Why should it be any
different than using my mail server? Please enlighten me :)
Thanks
