[Mailman-Users] 1.0b11 bug with underscores in member name?

I already replied in direct mail but realized that there is in
fact another bug burried in Terry Grace's report.

Addresses with underscores work fine, the problem below was IMO at the
Notes gateway as indicated by the error message.

However, mailman does not recognize the bounced address:

Lotus Notes says:
  ------- Failure Reasons  --------
  User  not listed in public Name & Address Book
  latoya_lemur at notes.wu-wien.ac.at

Mailman apparently matches "not" as the username and thus concludes:

    List:       Test-b8
    Member:     not at notes.wu-wien.ac.at
    Action:     Subscription not disabled.
    Reason:     Excessive or fatal bounces.
    BUT:        User not found.

It's certainly not easy to recognize all possible gateway error
message formats, so maybe that's not even a bug after all ;)


[earlier direct mail]

According to Grace, Terry:

That's not Mailman's fault, the Lotus Notes(?) internet mail gateway
involved rejects the mail.

This happens quite frequently, as far as I know, especially if the
Lotus mail gateway loses the contact to the Lotus server which has the
address book.

P.S: Some of our lists also have subscribers with underscores in their
