[Mailman-Users] Mailman suddendly stops sending any emails

[Andy Smith]

Hi,

    ok seems there was a little misinformation regarding this :S

Turns out the issue was no mail was set for all the users in the list,  
possibly relating to the bounce handling. Im struggle to understand  
what is bouncing what to cause this, is it mailman get undeliverable  
mail errors or what (I have no reason to believe mailman has any issue  
delivering mail to any of the members)

thanks Andy.
