The James project is made up of JamesVolunteers, people who donate their time and creativity to produce the James mail / messaging server. Ok, let's face it: everyone likes to know when people are using their code. It helps to invigorate the volunteers, and encourages other users.
So if you are using James, please take just a moment, click the edit link below, add your name, maybe a comment or two, and let the James Community know.
Heath Borders-Wing - I use James as my personal SMTP server when I switched ISPs and was no longer provided with an SMTP server. James was extremely easy to set up and use. I've never really worked with email administration before, and I was surprised at how easy it was to put on my system.
{ { { DevTech } } } - we use James as our primary mail server, serving a dozen or domains, a couple of hundred users, and a handful of mailing lists.
Marc Chamberlin - I use it on my personal computer to help several non-profit organizations, manage their mail lists, virtual domain email addresses, and to automate the posting of newsletters and other dynamic web page content to various web pages on their websites. (It works in close conjunction with my Jakarta Tomcat JSP / webserver.) The most interesting application is to handle the automated storage into a database and distribution of images taken from a telescope observatory!
EJB Solutions / Eric Weidner - I've been using James for about 2.5 years. It's always been extremely useful and extremely stable. I'm glad that the "alpha" label has finally been dropped because some people would shy away from "alpha" code. James has always been more feature rich and stable than that. We've included James in our product Out-of-the-Box which is an integrated Open Source distribution that helps reduce the barriers to Open Source software implementation and get more exposure to projects such as James which is one of my personal favorites.
Jim Rollo - I've been using James since 1.2 for personal use; I'm very pleased with its integration with MySQL databases and I look forward future extensions of functionality and improvements. I think James has great potential to become a stable enterprise-scale mail server.
Martin Woolley - I'm currently prototyping an email oriented application with James. So far I'm very impressed and believe adopting James will save me a considerable amount of work.
WM-Data Consulting / Ville Rinne - We are an IT-consulting company based in Finland. So far we've used James for one project where we developed a custom email-proxy for a client. James actually helped us win the project since everybody else had offered solutions based on more "traditional" mailers. James gave us the edge by being extremely easy to customize to suit our needs and the fact that it was written in Java.
Contrado Technologies / Jeroen van Bergen - We have used James as a component in a system that sends out large amounts of personalised emails to customers that have signed up for email notifications. The emails themselves are generated by the Velocity template engine. James is used as an MTA with the additional functionality of storing the status of each individual email in a database for tracking and reporting purposes. The latter is implemented in a few custom matchers and mailets. James has proved to be very easy to extend / modify to meet our specific needs.
Chris Means - I've been using James as my home mail server for about a year now, and am very happy. I've even developed a few custom mailets for special handling and SPAM detection / flagging. Keep up the great work guys!
Saphor GmbH / Marc Küster - We are a German IT company that specializes in Java applications, internationalization and XML-related services. We use James for many months now as our company mail server in line with our general commitment to Java-based Web technologies.
Torbjörn Gannholm - Have been using James for a few months at home, just out-of-the-box. Works very well. Got good support from the mailing list when I needed it. Thanks!
Neeraj - I've tried James after a long time again - it seems to be constantly improving - congratulations! Thanks!
René - I find James to be a snap to install and start using!
David - I just started using it. It is easier to use but I found a annoying problem about the James server that every time I retrieve emails, the emails are gone forever, I don't know if it is the correct behavior or I didn't set it up correctly. Thanks if anyone can answer my question.
Please ask questions on the James User's mailing list. The Wiki is not used for that purpose. With respect to your "problem", that is a client setting, having nothing to do with James. Most mail clients default to deleting e-mail after they retrieve it.
William Zhu - new to james. wonderful world ! I can receive email from james server, but I can't send mail out (exclude the local users).
AndrewCOliver - I use JAMES for all of SuperLink's mail/list serving needs. We're pretty happy with it minus the filesystem mail repository.
-- cool.
GeoffreyRush - I use JAMES for I use Avalon framework to develop my back-end server,and i want to integrete James into my app server.
Jim Henshaw - After looking all over for a free email server, I finally found one. Although it took a lot of reading and experimenting to get it working, I love it. I use James for my personal domain because it looks more professional to have your own domain email. Thanks for all your hard work and for the mail archive which helped me to figure out my mistakes.
Nicola Ken Barozzi - James is a killer project, based on solid ideas and in my company intranet it simply works (TM).
The cool thing about it is that it's pipeline based, so that it's very very easy, I'd say near to trivial, to make messages do what you want by using mailets, and usually the ones you need are already there.
My net admin loves the baby: MySql as a backend (she loves to be able to do queries and simple backups), a simple config file with spam blocking, the thing installed as a service, and nothing to touch 
Oh, and memory usage is really stable, with no noticeable load problems on the server. Ok, the load is light (50 users), even if we have multi-mega attachments for the technical drawings, but it can do all and it's easy and stable.
I love it
{ { { JournalScape.com } } } - We use James as our standard mail server. We are sending a constant stream of { { { New Journal/Blog } } } Entry emails to internet users who have subscribed to the online journals http://www.journalscape.com
Toni Bennasar - I'm developping a open source yahoo groups 'look-likes' mailing lists servers called jGroups and James and the Mailets saved me of write MIME parsing and other bad things. James is an indispensable requirement. Thank you, people.
{ { { Mathew McBride } } } - After my ISP box kept on being flooded with Swen worms, I decided to use James to deliver my mail. It just works!
