[Mailman-Users] Force a probe message?

[David Gibbs]

Folks:

Anyone know if there is a way to force a probe message to go out for a 
subscriber?

I have a subscriber who's mail appears to be bouncing ... but it's going 
back to the original author of the message and not the list address.

I'd like to force their subscription into such a state as a probe 
message is sent out so it can be disabled if the email address is indeed 
broken.

Thanks!
