I briefly had them doing authenticated SMTP-over-SSL but that caused a
lot of trouble trying to keep it working on their side and parents are
notorious for forgetting what their passwords are. :)

Then it broke completely when verizon's dialup got put into the RBL that
I use. (Which I find amazingly ironic considering the fubared state
their SMTP servers are in presumably to prevent SPAM...)
