In the past, you were able to send email to LAME zones. i.e. a server which did not respond authoritatively. The question I have is when did this change, and if so, is it a tuneable. The example I gave was supercom.ca. Both their servers respond LAME in the classic sense. ns4# mail -v postmasterd@supercom.ca Subject: test ignore EOT postmasterd@supercom.ca... supercom.ca: Name server timeout postmasterd@supercom.ca...
