Redmine

Spent an endless amount of time on configuring email in redmine.
After digging through ths issues it turns out that there was plenty of people that had this issue.

Can I suggest that the config/email.yml file gets updated with some details on the various common configs.

Try to find the config to use if you happen to be on the same subdomain as the mail server and you can send email with out authentication. Is authentication false, plain, none or is the usernames just blank or what exactly is the issue.

My contribution to this is that neither plain, none nor false worked for a non-authenticated version. This might be a bug or a lack of docs.
Further I do not feel comfortable having passwords in plaintext in config files. So falling back to authenticated mode was a hard one.

Too much time down the drain on just getting email up and running.
