The point of Jose Maria is that this is Broken As Designed, not WAD. If
there are 10 RYERSON.CA addresses on a list at CEARN, mail to them will
be distributed by sending a single DIST job to CANADA01, which will then
generate 10 files to the mailer --> 10 files from CANADA01 to RYERSON. If
people were subscribed as RYERSON not RYERSON.CA, you would have a single
file to the RYERSON LISTSERV and not 10 (assuming RYERSON did run a
LISTSERV).
