SDU=standard dial up, the traditional tenner-a-month account
NDU=network dial up, the hundred-quid-a-month (or thereabouts) service where
Demon will route a netblock (size according to your business needs and RIPE
guidelines) to an ISDN-only dialup, rather than a single IP address.
BDU=business dial up, the special account for users of Microsoft Small
Business Server.  SBS is essentially NT Server, Exchange, modem pooling,
MS P(r)oxy Server and some other bits and pieces - it's a fairly specific
config at both the customer end and the Demon end.

Sorry, ETRN only works for BDU customers.  I'm suprised that Demon has problems
with an error code at the DATA stage - I'm certainly rejecting mail that way,
although I don't know if bounces are ever generated from the punts.  Or
do you really mean *during*, as in you can't interrupt the incoming DATA stream
with a 5xx to stop the punts sending?

I've got a nice procmail anti-spam kit that stops an *awful* lot of stuff
reaching me these days...
