Can anyone recommend a based open source mailing list software ?
The following would all be desired if possible:
- Java as the underlying language, as we have people who are experienced with Java
- Something which is packaged as a war and can be dropped into a Tomcat server
- A sleek interface
- Underlying data should be reasonably transparent
- Good support for groups - sometimes we want to send mail to everyone, sometimes only people working in a certain area etc.
This is for a non-profit tax-payer funded research organization, so open-source (free) is a high priority. Thanks.
