Greg,

It should now (with 1.0b7+) be impossible to subscribe a domainless
email address.  I've verified this with the Membership Management
interface, a normal user's use of the subscribe page, attempting to
subscribe via email directly, and using bin/add_members.

If this means that from now on, no one will encounter the problem, I'm
tempted not to investigate further.

My question to the developers is, how important do you think it is to
fix this problem for the early adopters?  You guys can `just' delete
the unqualified addresses and force those people to re-subscribe using
a now valid address.  Would this be a huge burden?

Of course, if anybody's seen this happen for qualified addresses, then 
obviously we need to debug it.
