I wanted to add an e-mail subscription option to our site and was wondering if anyone had a good recommendation or two? I am looking for something that would be hosted on my Linux dedicated server and preferably be written in PHP/mySQL.

I would like for the subscribe and unsubscribe processes to be automated. The more bells and whistles the better.

Thanks in advance,

Not a specific recommendation, but there are 46 listed here for you to take a look at: http://www.hotscripts.com/PHP/Scripts_and_Programs/Mailing_List_Managers/

Chicken,

Thanks for the link that is a very good reference.
