Maybe they should send a fax instead.

This one works, and is used by most sites that were used as a hop before.

Exists and is used.

postmaster@localhost is aliased to these names and others on many machines
with imaginative sysadmins.

This I don't know how to implement. Ready to listen suggestions.

By hacking the kernel to add a state machine and a timeout queue to the
socket open call ;) Can be done in 2 weeks. BTW 10 messages per user 
per minute is 600 per hour, and this is spam class already. Takers ?

Problem: When someone queues email for sending out (like me) and then
connects, there can be up to 50 messages in there. They all go out at once
because I pay for the phone. Suggestions ?
