Mailing List Problems

[lokeshtodi]

I am using pathhost as my web hosting provider. They offer mailing list feature called mailman however my mailing list is not working. I have tried contacting my host and they don't seem to reply back and mailman's offical website told me to have a look at this forum. Can anyone help me figure out how to start using my mailing list. I have made a mailing list and added members to it however whenever I try to send an email it does not work.
