SMTP Configuration problem


(Rafaliwaniak) #1

Hi there!

I’m trying to send email alert every time Graylog receive some [ERROR] message. However something wrong is with my configuration. Can anyone help to determine what’s wrong?

When I’m trying to send test message I’ve got this error:
An error occurred while trying to send an email! (triggered 31 minutes ago)
The Graylog server encountered an error while trying to send an email. This is the detailed error message: org.apache.commons.mail.EmailException: Sending the email to the following server failed : 10.4.2.99:465 (com.sun.mail.util.MailConnectException: Couldn’t connect to host, port: 10.4.2.99, 465; timeout 60000; nested exception is: java.net.SocketTimeoutException: connect timed out)

Your configuration looks fine to me - but the selection of ports, use_auth and use_tls are things to tinker with.

Apologies if you have already been through all these items - we had some trouble with email initially and these were the things we did first.

Things to check:

  1. Can you telnet to your email server on port 465 from your graylog server? Can you ping it?
  2. You might try port 587 instead of 465 (this can be dependent on your email server’s configuration).
  3. Does this account work correctly outside Graylog? Are you able to configure an email client using the creds, port and ip listed?

Thank for your suggestion. I’ve got a problem with my email server conf. Indeed, graylog.conf was fine.

You can close this topic. Thanks!
