Class MailSenderService

java.lang.Object

com.serinity.accesscontrol.service.MailSenderService

public final class MailSenderService
extends Object

Utility service responsible for sending emails using SMTP.

This class provides a centralized method for sending HTML emails through an SMTP server configured via environment variables loaded by EnvironmentVariableLoader.

The class uses the Mailer library to construct and send emails with the specified subject, HTML content, and recipient.

The SMTP server, port, username, and authentication token are retrieved from environment variables. If the email cannot be sent due to an SMTP or mail-related exception, it is caught and printed to the console.

Exposed functionality:

• send(String, String, String) – Sends an HTML email to a specified recipient.

Example usage:

MailSenderService.send(
    "zouariomar20@gmail.com",
    "Welcome!",
    "Hello World");

Exceptions:

• com.icegreen.greenmail.util.MailException - Caught internally and printed if the email cannot be sent.

SMTP configuration must be correctly set in environment variables; otherwise, email sending will fail.
