SMTP Relay Setup

To send transactional messages using JangoSMTP (or if you are a JangoMail user, using the SMTP side of JangoMail), our general relay configuration settings are:

1. Relay (set the outgoing SMTP server) to express-relay.jangosmtp.net.

2. Use port 2525 or 587. You can also use port 25, though it is often blocked by various ISPs. If you want to use TLS/SSL secure settings, use port 465 at relay.jangosmtp.net.

3. Authenticate using your JangoSMTP account’s username and password. This is the primary account username and its password. Additional logon usernames (if you have created any) cannot authenticate to use JangoSMTP. Relay authentication is restricted to the primary username. JangoMail users would also authenticate using the primary username/password.

4. If you are sending from a known and public IP Address, you can alternately authenticate by entering your sending IP address into your account under Settings. If you enter an IP address into your account Settings, it can take up to 15 minutes before the address is detected (usually happens within a minute or two, but it can take longer, so if initial tests fail, please wait the 15 minutes). JangoSMTP access to this is Settings > Authentication > SMTP Authentication.

In JangoMail, go to Settings > Transactional Emails > IP Addresses.

If you are a home or office user using DHCP, you can still use your IP address for authentication, but keep in mind that the address may change (on you) without notice, so if your messages stop sending, be sure to check your current address versus what is entered in your account.

You can also try our SMTP testing tool. Enter your username/password, and it will check ports and send a test message if authentication and port access are good.

JangoSMTP supports SSL/TLS

Note: JangoMail accounts have access to the SMTP relay, but if all you need is the ability to send transactional messages via our SMTP relays, your account should be under JangoSMTP, not JangoMail.
