It looks like you aren't following the instructions correctly.

First of all, the "na," is part of the example bad address. I.e. in the
example the bad address is "name at example.com" with a comma in the
middle of "name" making it "na,me at example.com"

What you need is

  m.removeMember('user at host.tld\r\n')
or
  m.removeMember('user at host.tld\x0d\x0a')

or if that doesn't work

  del m.members['user at host.tld\r\n']
or
  del m.members['user at host.tld\x0d\x0a']

Right, it only helps prevent adding one.
