Hi @giridhar0813,

Welcome to the :grafana: community support forums !!

We are excited that you joined our OSS community. Please read about some of the FAQs in the community :slight_smile:

This seems to be not related to Loki but a general issue with the configuration. You can do a basic verification by simply testing the above configuration via telnet command.

In your helm chart, please define the SMTP port as well.

You can have a look at this reference post to see what other SMTP settings are required to make it work correctly.

Let us know if this helps.
