This was fixed in Mailman 2.1.6. Note that strictly speaking any printable ascii character is allowed in e-mail address local-parts if quoted, and we don't actually parse the local part to determine if it or characters within it are quoted, so there may be email addresses which are technically valid which we don't accept, but we have no plans to for further changes in this area.
