Hello, I’m encountering an issue while configuring the Alert channel type email in Signoz. In the documentation provided here, it mentions that I need to configure a few environment variables. However, in the UI, when configuring it, it only asks for the recipient mail address. Where do I need to configure those values to use the Email Type alert channel? I deployed Self-Hosted Signoz using the Helm chart in Kubernetes.

i think you need to update it in the docker compose for the container signoz-alertmanager

If we’re using the Helm chart, do I still need to make changes in the Docker Compose file, or is it handled differently? Specifically, I’m referring to the configurations mentioned here.

@kamal sai perla are you using latest version of SigNoz helm chart?

Yes @Prashant Shahi version: 0.42.0 appVersion: 0.46.0

can you share the error logs that you are seeing when trying to send email alert?

can you check alertmanager logs?

^ For alertmanager, @Srikanth Chekuri would be the best person to answer that.

Hi @Srikanth Chekuri, Can you please help with this request related to disable TLS for SMTP.

@kamal sai perla Did you manage to resolve the situation? I have exactly the same problem and I honestly think it is not possible to disable TLS for SMTP. If we check the code in the repository the variable is hardcoded:

return GlobalConfig{

ResolveTimeout: resolveTimeout, HTTPConfig: &defaultHTTPConfig, SMTPSmarthost: defaultSMTPSmarthost, SMTPFrom: defaultSMTPFrom, SMTPAuthUsername: defaultSMTPUsername, SMTPAuthPassword: Secret(defaultSMTPPassword), SMTPAuthSecret: Secret(defaultSMTPAuthSecret), SMTPAuthIdentity: defaultSMTPAuthIdentity, SMTPHello: "localhost", SMTPRequireTLS: true, PagerdutyURL: mustParseURL("https://events.pagerduty.com/v2/enqueue"), OpsGenieAPIURL: mustParseURL("https://api.opsgenie.com/"), WeChatAPIURL: mustParseURL("https://qyapi.weixin.qq.com/cgi-bin/"), VictorOpsAPIURL: mustParseURL("https://alert.victorops.com/integrations/generic/20131114/alert/"),

I’m unable to resolve this currently. As you mentioned, the current code doesn’t support disabling TLS for SMTP. We’ll need to wait for them to make the necessary code changes @João Cardoso
