Traditionally mail software is set up to send a few specific domains
like .bitnet and .uucp to clever relay hosts, and to send the rest
by MX record. However the number of top level domains keeps changing
and it is hard to keep track of which ones understand MX records, so
I do it the other way: I send mail to well-behaved top level domains
by MX and send all the rest to our local intelligent mail relay.

Unfortunately our local intelligent mail relay is getting heavily 
overloaded. So I'd like to send as much by MX as possible. Would anybody
like to give a list of well behaved top levels. At the moment I have
the 3-letter ones plus au, nz, se and ac.uk. It has been put to me the 
fr and ch are also ok but I'm not sure.

Of course I could find out which domains our relay has special (non-MX)
rules for, but that keeps changing.
