Hi everyone at open source Apache James, This is to notify that James is similar to a closed source project. Necessary documents at https://james.staged.apache.org/james-distributed-app/3.7.3/operate/ are currently not found (404). Documents on James website are outdated with the latest build.
Configuring James now for new users requires to look into source code, logic, which is a crazy idea. Yes, it's always easier with technical services behind James, but how to be sure that there are no "unexpected" errors occur during operation in the future, when valuable data going huge. I concern this because james's been contributed & maintain mostly by companies providing technical services on James. If any companies are not at Google, Microsoft, etc level, it's better to build own distributed business-logical mail system based on postfix, dovecot, familiar db shard & replication, etc. It's peace of mind and faster building than current document-hidden Apache James. It's not too difficult unless you want. Hope James project is great in the future. Regards, Huy Van
