Open
System > Settings from the admin menu. The page is split into System, SMTP, Authentication and GeoIP.Save one section at a time. When a section depends on another one, configure the dependency first. For example, email-based login modes should only be enabled after SMTP has been saved and tested.
System
System Name
This is the name shown inside the installed dashboard. Use a short name that operators recognise, such as your company name, platform name or datacenter environment.
Do not place secrets, license keys or private hostnames here. This name is meant to identify the installation, not store configuration.
SMTP
SMTP controls email delivery. DCIM uses it for login codes, account emails and notification workflows. Keep SMTP disabled until the host, sender and credentials are correct.
Status
Use
DISABLED while you are entering or testing settings. Switch to ENABLED only after a test email is delivered successfully.Host
Enter the SMTP server hostname, for example
smtp.example.com. Do not include a protocol such as https://.Port
Use the port required by your mail provider. Port
587 is common for submission with STARTTLS. Port 465 is common for implicit TLS.Use implicit TLS
Enable this when the SMTP provider expects TLS immediately when the connection opens, usually on port
465. Leave it disabled when the provider uses STARTTLS, commonly on port 587.From Name
This is the sender display name users see in their mailbox. Use a clear value, such as
DCIM or your platform name.From Email
This is the sender email address. Use an address that belongs to a domain your SMTP provider is allowed to send from, such as
[email protected].Username
Enter the SMTP account username. Some providers use the full email address; others use a separate account name.
Password
Enter the SMTP password or app password for the SMTP account. If a password is already saved, leave this field empty to keep the current password.
Authentication
Authentication controls how admin and access users sign in. The default mode is password-only because it does not depend on email delivery.
PASSWORD_ONLY
Users sign in with email and password. Use this during first setup or when SMTP is not configured.
EMAIL_OTP_ONLY
Users sign in with a code sent by email. Use this only when SMTP is enabled and test emails are delivered reliably.
PASSWORD_AND_EMAIL_OTP
Users enter their password and then confirm an email code. This is the strictest built-in login mode and should only be enabled after SMTP is working.
GeoIP
GeoIP is optional. Enable it only if you have MaxMind credentials and want DCIM to use GeoIP databases for IP location data.
Status
Keep this set to
DISABLED if you do not use MaxMind. Set it to ENABLED after the account ID and license key are available.Account ID
Enter the MaxMind account ID for the account that owns the license key.
License Key
Enter the MaxMind license key. If a key is already saved, leave the field empty to keep the current key.
