Here's another tale of undeliverable email. It seems that [at least] one of those organisations you mention assigns IP addresses for its ADSL customers from the same blocks as dial-up. Which means that organisations using MAPS-DUL reject email from teleworkers (or indeed people running businesses with an ADSL connection) who run their own SMTP servers. -- Roland Perry
