Comment 1 for bug 557935

1) It is only by accident I saw this report. All Mailman bugs, even for 2.1
should be reported at <https://bugs.launchpad.net/mailman>. The sourceforge
tracker is only available so old URLs to bug reports still work.

2) You are correct about the bug, but the fix

 except (Errors.MMBadEmailError, Errors.EmailAddressError):

is redundant as Errors.MMBadEmailError is a sub class of Errors.EmailAddressError so just changing it to

 except Errors.EmailAddressError:

is just as good. The real problem is Utils.ValidateEmail() considers any address which has non-ascii characters to be 'hostile' and raises Errors.MMHostileAddress which is another sub-class of Errors.EmailAddressError.

The fix will be in the next release.
