Unable to use gmail to send alerts

[ylmcc (Kyle)]

Hi guys,

I have tried following “How to send email alerts using Gmail” to no avail.

The error I am getting is " * Error: Notification has email recipients and is triggered, but sending emails failed. Sending the email to the following server failed : smtp(.)gmail(.)com:587"

My Email configuration is the following:
transport_email_enabled = true
transport_email_hostname = smtp(.)gmail(.)com
transport_email_port = 587
transport_email_use_auth = true
transport_email_use_tls = true
transport_email_auth_username = email
transport_email_auth_password = password
transport_email_from_email = email@company.com

I am unable to see any error in depth as the logs when configured for debug only show the following:
2019-11-29T09:08:59.748-05:00 DEBUG [EmailSender] Sending mail to test@email.com

I cannot find any traces or anything more stored in /var/log/graylog-server/server.log

Any help on this would be fantastic.

How to send email alerts using Gmail

Sending email alerts Because I know it’s not obvious from the interface and the documentation is vague, I’m writing this tutorial to document the process for configuring the email settings for Graylog and for configuring alerts to be sent via email. I’m using CentOS7 as a base, so instructions will differ if you’re using the OVA or another distribution. Configuration is also for Gmail as that is our email provider, so adapt to your own service where necessary. Configure graylog server Firstly…

Hi Jan,

I realised I was not seeing the detailed messages as I had not included the user to be notified. Once I did that I found out that my password was not correct. Google wanted me to generate an app password. Once I did that I could then send emails.

Thank you for your input!
