Logging into admin interface
Once you have a blank install of WebMail Lite 8 set up, you can navigate to its main page and log into admin interface by supplying superadmin as username, and an empty password.
NB: Unlike previous version 7 of the product, WebMail Lite 8 doesn't have a separate login page for administrator, it's the same main page of the product interface used.
Right after entering admin interface, you're strongly advised to set up a password. If you wish, you can change admin login as well.
In the future, if you forget admin username or password, check
data/settings/config.json file, you'll find AdminLogin there in clear text. To reset admin password, set empty value for AdminPassword, then log in with empty password and set a new one.
Another critical part of setting up the product is configuring database settings. It's assumed that you already have a database created, fill in the connection details, press Save, then you can Create Tables.
Setting up mail servers
To access your accounts, you would need to set at least one mail server. Under Mail Servers tab, click Add New Server button. You'll need to supply IMAP and SMTP server connection details, as well as the complete list of domains that belong to this server.
Note that you will not need to add users manually - instead, users simply log in from main page by specifying their email and password. And based on domain part of their email address, a certain mail server is used, out of those you have added in this step.
Configuring Notes support (optional)
If you wish to make use of Notes feature, enable it as described at Enabling Notes support documentation page. Note that the module forces creating Notes folder in every email account users log into, unless the folder exists there already.
Configuring Filters (optional)
If you'd like to enable Filters tab in account settings, you need to configure ManageSieve integration. The same applies to setting up Forwarding and Autoresponder.

In v8.3.5, CSRF protection was substantially revised and may require web server reconfiguration. We're now shipping .htaccess file to ensure authentication headers are sent through, but if you're getting Error 500, that may mean you have mod_rewrite disabled. And if you receive "Cookies need to be updated. To continue, please click here or reload this page." message, make sure .htaccess file is actually read by the web server. Read more on this at CSRF protection documentation page.
