Alert list member Rich Kulawiec <rsk at gsp.org> told me about a 
configuration error in mail on pilot.

(I would normally send this to steering at trilug.org, instead of blasting 
the whole list, but that address is closed and for steering committe 
members only.)

I'm happy to do the leg work to fix this problem, if that helps,

Thanks Joe
