Hey guys... I am looking to get my feet wet for the first time with a mailing list manager. I am looking for a script that can handle all my subscriptions nicely and send out HTML newsletters. Does anyone know of a good mailing list script (preferrably PHP) that has some great features and good support? Any recommendations are greatly appreciated... commercial or free. Thanks for your input!

Both phplist http://www.phplist.com and dadamail http://mojo.skazat.com/ seem to both get great reviews so you may want to check those out.
