[Mailman-Users] rare problem

[Jesús Oliván]

We've got this mailman version in a production environment and users 
that are not suscribed to a list cannot publish any message and the 
worst fact is that sender cannot know if his message has been sended, 
cause "From" address doesn't exist. Is there any modification we can do 
(some code inside a function) to patch this little bug?

Thanks for your great help =)
