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

[Grace, Terry]

I have a list member with underscores in the username (eg
username_at_hostname at 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:

ontent-type: text/plain; charset=us-ascii

This is a Mailman mailing list bounce action notice:

    List:       Nortel-list
    Member:     not at domain.com
    Action:     Subscription not disabled.
    Reason:     Excessive or fatal bounces.
    BUT:        User not found.


The triggering bounce notice is attached below.

Questions?  Contact the Mailman site administrator at
mailman-owner at tgrace.com.
