To set up an SMTP email server in aaPanel:
Install Mail Server Plugin: In aaPanel, navigate to App Store, search for the Mail Server plugin, and install it.
Configure Domain and MX Records: Set up your domain and add the appropriate MX records with your DNS provider to ensure email delivery.
Open Ports: Make sure port 25 is open for outgoing emails, along with port 465 (SSL) and port 587 (TLS) if needed, especially on your VPS with port 25 open.
SMTP Configuration: In the mail server settings, configure SMTP by setting the server domain, hostname, and enabling SSL/TLS on port 465 or STARTTLS on port 587.
Test Email: After configuration, test sending emails from your server to verify everything is working properly.
This setup will allow you to use SMTP for sending emails via your aaPanel server.
