Hi team,

I am unable to setup the SMTP for Alertmanager and query service.
Getting the following error:
```level=error ts=2024-08-20T11:36:13.414Z caller=api.go:808 component=api version=v1 msg="API error" err="server_error: establish connection to server: dial tcp: address tcp/\"587\": unknown port"                  ```
tried different ports like 25, 465 as well same error with ports changed.
