We often get inquiries from customers telling us that they're unable to relay emails through
relay.jangosmtp.net. Here is a list of the most common reasons why it doesn't work.
- Your Internet Service Provider (ISP) is blocking access to external email servers. By default, the SMTP server listens on port 25, and many ISPs block connections on port 25 in order to prevent you from emailing through an external email server. For this reason, our SMTP server also listens on port 587 and 2525. You can also connect securely over SSL/TLS on port 465. You can test connectivity from a Command Prompt by typing:
telnet relay.jangosmtp.net 25
Successfully connecting to relay.jangosmtp.net
If that doesn't work, try:
telnet relay.jangosmtp.net 2525
You should get a response from the server as shown in the screenshot above. - You haven't setup a proper authentication method. In order to relay emails through relay.jangosmtp.net, you must login to your account, go to Settings --> SMTP Relay, and authenticate either by IP Address or Username/Password.
- You are connecting to the wrong server. We've had customers attempt to connect to relay.jangosmtp.com, relay.jangomail.com, and relay.jangomail.net, all of which are incorrect. The correct server is relay.jangosmtp.net.
- You are manually inputting SMTP commands in order to complete a SMTP transaction. Unfortunately, unless you manually input the data for a proper and well-formed email message, including a Subject and a Message, our system will discard it.
How do you know if your email goes through the relay server properly? You will see your email almost instantly in Reporting after you send it.
