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@notes.wu-wien.ac.at
Mailman apparently matches "not" as the username and thus concludes:
List: Test-b8
Member: not@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:
I have a list member with underscores in the username (eg username_at_hostname@domain.com). When a message goes out to the list the following is returned to the list admin and the message is never delivered to the user: [...] User not listed in public Name & Address Book username_at_hostname@domain.com
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 address.
