Which Mailing List Manager Do You Recommmend?

bobdinkel writes "While I know it isn't the most glamorous thing, mailing lists are a fact of life. And they gotta be managed by someone. In my organization, that someone is me. For whatever reason (they won't exactly say) the powers that be do not want to use majordomo and sendmail. So I pose this question to you, dear reader: What is the best MLM - MTA combo in the Unix world?" One only needs to shake a stick to see the amount of software available that handles mailing lists. Which ones have suited your needs?
