php-eml
Apr 4, 2005 · 1 minute readphp-eml is a sourceforge open source project I started a while back to develop a php based email mailing list. At the moment this in at a stage where it works but is not really pretty or easy to install unless you enjoy a little sysadmin.
Both these, and some new features should be added in the future, time permitting.
See www.php-eml.com for more information or to download the source.
