Yes. SMTP servers are _supposed to_ relay mail by default; it's part of making the net robust against single points of failure, and transient outages. The same goes for DNS zone transfers, actually: let there be stealth secondaries, the more places my data is backed up, the better. The level of maturity of the average Internet user these days is way, way below what it was, back when the NSF would prosecute you for commercial use of your net connection. > As for the approach, I'm pretty sure that those aren't original to > qmail.

So did Greg Haerr's UCSD email system, back in the 70's (sending and getting mail were totally seperate programs -- had to be, to run in small model on a PDP).
