Following Jason's suggestion many moons ago, I modified Mj::Addr to make
it standalone by commenting out the logging. I use this as a sanity
check when I receive a bunch of email addresses for a new list. I have
just discovered that if I feed it an email address with a space like so:
it finds it to be valid. FWIW, the old validate_addresses script does
the same. Is this an oversight, or is my use of the module inappropriate?
I realize that if you try to subscribe such an address to the list
via the usual interface, it will indeed fail.
