Best FREE self-hosted OR webhosted mailing list script/service with bounce handler

[marcnyc]

I am on a desperate search for a mailing list/newsletter software/app or service with the following features:
- free
- runs as a service on a website or as a script on my server (as long as it doesn't require php.ini changes or other things I can't do on a non-dedicated hosting account)
- has a bounce handler that will remove email addresse that are undeliverable

I've tried phplist and I didn't particularity like it. The easier and more immediate the better.
Thanks for your suggestions.

Last one I used was poMMo, which was pretty good, but does not appear to have been updated at all in the last 2-3 years, so I'm not sure if there's any support still. phpList seems to be one of the most popular now, but I don't have any personal experience with it.
