[Mailman-Users] Email problems

[Bayou Bhangra]

I sent an email yesterday using your program, our host is advancednetworkinghosting.com and we had some serious issues.  Normally, when we send a mail to our list, bayoubhangra at bayoubhangra.com, the only address we can send it from is info at bayoubhangra.com, but instead, anyone that responsed to bayoubhangra at bayoubhangra.com, their email went out to the entire list.  What went wrong?
