we are not "attracting" spam, but some spammer just happen to use our
address as the "sender" of all the junk they spew out.

then some badly configured mailservers bounce the spam, but does not
specify that it actualy is a bounce. And we get the backscatter. It's
just coincidense what email address the spam engines chooses for a
sender address. at the moment it is debian-edu@l.d.o it will probably
last as long as the spam run lasts. (a few weeks, perhaps a month or 2)
and  then it's someone else that gets the unfortunate honor of beeing
the "sender" of spam.

There are tools like SPF and Domain keys that are used to verify a
sender address. but they are not a silver bullet, and have drawbacks.
A badly configured mailserver would probably not heed it (SPF) anyway so
the difference would be nill.
