SMTP Relay Setup

Note: Please read info about Delivery Setup before starting to send with JangoMail/JangoSMTP. 

SMTP Relay Settings

To send transactional messages 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. Port 25 is often blocked by various ISPs. If you want to use encryption, port 465 provides explicit SSL/TLS access, and STARTTLS can be used with any port except 465 and it must be enabled on the client. 

3. Authenticate using your account’s username and password. This is the primary account username and its password. Additional/Other login usernames can only authenticate to use the express-relay.jangosmtp.net. This needs to be turned on in the Additional/Other login settings. 

We support PLAIN and LOGIN authentication schemes across all ports and all SSL settings. Please keep in mind that, due to security reasons, our relay service will not respond to the Ping utility when used to test the reachability of our service.

Authenticate by IP Address

If you are sending from a known and public IP Address, you can alternately authenticate by entering your sending IP address into your JangoMail/JangoSMTP account. 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).

To add authorized IP addresses, go to Settings → Transactional Settings → Relay IP Authentication.

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