[plt-scheme] hotmail woes

Presumably due to hotmail's news space limiations, I get the following 
responses to pretty much all mail sent to this list:

 <mathieu_paradis at hotmail.com> ... transport smtp: 552 Requested mail action aborted: exceeded storage allocation
 <manigal at hotmail.com> ... transport smtp: 552 Requested mail action aborted: exceeded storage allocation
 <leon_heller at hotmail.com> ... transport smtp: 552 Requested mail action aborted: exceeded storage allocation
 <immanuel_litzroth at hotmail.com> ... transport smtp: 552 Requested mail action aborted: exceeded storage allocation
 <gregory_lampshire at hotmail.com> ... transport smtp: 552 Requested mail action aborted: exceeded storage allocation

If anyone knows of alternative addresses for any of these people,
please let me know -- I'm going to take their hotmail addresses off.

Thanks,
Shriram
