Mailman not receiving mail?

Hello, Have anyone out there installed mailman on a SLOX or SLES server and got it to run? I can only get the web based part to function. Any attempt to send e-mail to the lists, admin or anything that has to do with mailman fails. I guess it must be some mistake in configuring the alias mapping, but I can't for my life find out what/where I went wrong. So, please help me out here! Anders Norrbring Norrbring Consulting
