Mail Provider Integrations
WHMCS's mail provider integrations offer the choice of several configuration options, allowing you to take advantage of more service-specific features and advanced security.
- Microsoft is available in WHMCS 8.6 and later and supports all Microsoft Azure®-compatible email services.
- Google, Mailgun, SendGrid, and SparkPost are available in WHMCS 8.0 and later.
- PHP mail and SMTP are available in all versions of WHMCS.
How Do I Configure My Mail Provider?
You can configure your mail provider in the Mail tab at Configuration () > System Settings > General Settings.
- For instructions using Microsoft, see Setting Up Microsoft As Your Mail Service Provider.
- For instructions using Google, see Setting Up POP3 Importing via Google.
- For instructions using Mailgun, SendGrid, and SparkPost, see Configuring WHMCS To Use Other Mail Providers.
- For instructions using SMTP, see Configuring WHMCS to Use SMTP for WHMCS 8+.
To configure Microsoft, you will need to create an app in the Microsoft Azure® console and configure the mail provider in the Mail tab at Configuration () > System Settings > General Settings.
If you use WHMCS's Google or Microsoft® integrations, you get the full benefit of those services' additional features, including OAuth2, which provides more security than traditional username-and-password authentication.
Security and OAuth2
OAuth2 is a technology that authorizes apps or services like WHMCS to access another service, such as a Gmail account. It's more secure than traditional username-and-password authentication. In addition to its security benefits, some mail providers require OAuth or have announced a requirement for it in the future.
How Do I Configure Services for Email Importing?
WHMCS supports POP3/IMAP, Microsoft, or Google service providers for email importing. Email importing is distinct from your WHMCS installation's mail provider.
You can configure email importing when you create or update a support department at Configuration () > System Settings > Support Departments.
