[Mailman-Users] Restore Mailman lists to default setting

[Hung Phan]

Hello,

We have a few lists that have different settings than Mailman default  
settings. We believe that some of these settings are conflicting and  
create two issues that we are currently experiencing (subscribe email  
not sent out and sender not receive posted message)  We went through  
changing the settings on the lists but not making any difference. With  
newly created lists, they don't have the issue. Is there a way to  
restore a list setting to the default setting but keep the membership?

Thank you,
