Email configuration is essential for Leconfe to send notifications, invitation emails, password reset links, and other communications to your conference participants. Without proper email setup, these critical messages will not be delivered.

Leconfe supports any SMTP-based email service. Below are some commonly used providers:

• Gmail SMTP — Free for limited sending; good for small conferences
• SendGrid — Reliable transactional email with a generous free tier
• Mailgun — Developer-friendly email API with flexible plans
• Amazon SES — Cost-effective at high volume; ideal for large conferences

Configuring Email in the .env File

After successfully installing Leconfe, the next step is to configure the email settings. Follow the steps below:

Step 1: Navigate to your Leconfe installation directory and locate the .env file in the root folder.

Step 2: Open the .env file with a text editor. Find the email configuration section:

MAIL_MAILER=smtp
MAIL_HOST=smtp.gmail.com
MAIL_PORT=465
MAIL_USERNAME=your-email@gmail.com
MAIL_PASSWORD=your-app-password
MAIL_ENCRYPTION=tls
MAIL_FROM_ADDRESS="your-email@gmail.com"
MAIL_FROM_NAME='Leconfe'

Step 3: Update each value to match your email provider:

• MAIL_MAILER — Use smtp for most providers
• MAIL_HOST — Your SMTP server address (e.g., smtp.gmail.com for Gmail, smtp.sendgrid.net for SendGrid)
• MAIL_PORT — Common ports: 587 (TLS), 465 (SSL), or 2525
• MAIL_USERNAME — Your SMTP account username or email address
• MAIL_PASSWORD — Your SMTP account password or app-specific password
• MAIL_ENCRYPTION — Use tls (recommended) or ssl
• MAIL_FROM_ADDRESS — The sender email address that participants will see
• MAIL_FROM_NAME — The sender name (e.g., your conference name)

Troubleshooting: Emails Not Being Received

If emails are not arriving in recipient inboxes, you may need to add an EHLO domain configuration. This is especially common when your conference is hosted on a university subdomain. For example, if your conference URL is conference.university.ac.id, add the following line below your email settings in the .env file:

MAIL_EHLO_DOMAIN="university.ac.id"

Important: Only write the main domain (e.g., university.ac.id) — do not include the full subdomain such as conference.university.ac.id.
