Module Description

⚠️ A secure connection (https) is required to generate OAuth tokens!

The MultiSMTP OAuth module addresses an issue that has become common among Dolibarr users: sending emails in a reliable, secure, and personalized manner for each user, while complying with the security requirements imposed by providers such as Microsoft 365 or Gmail.

With this module, each Dolibarr user can have their own SMTP configuration, independent of other accounts. Emails (quotes, invoices, reminders, free emails, etc.) are thus sent directly from the user's real email address, enhancing the credibility of exchanges and deliverability.

🔐 Enhanced security with OAuth2
MultiSMTP OAuth allows you to use OAuth2 authentication, completely avoiding the use and storage of SMTP passwords.
This method is now recommended, or even required, by many email providers (Microsoft 365, Outlook, Gmail, etc.), ensuring a high level of security and compliance.

⚙️ Main features
•    SMTP configuration per user in Dolibarr
•    OAuth2 compatibility (Microsoft 365 / Outlook / Gmail)
•    Elimination of traditional SMTP passwords
•    Centralized management of OAuth tokens in Dolibarr
•    Option to enable IMAP to retrieve sent emails
•    Works in addition to Dolibarr's global email configuration

🎯 Typical use cases
•    Sales teams: each sales representative sends emails from their own address
•    SMEs/firms: compliance with Microsoft & Google security policies
•    Multi-user or multi-service environments
•    No more SMTP blockages due to security restrictions

MultiSMTP OAuth is the ideal solution for professionalizing, securing, and ensuring the reliability of email sending in Dolibarr, while adapting to changes in email standards.
