**Hello, Glad to be here! I’m facing an issue while testing SMTP for Alertmanager. Even though

require_tls

is set to

true

(default), I’m getting the error:

'require_tls' is true (default) but "<http://mail.domain.net:26|mail.domain.net:26>" does not advertise the STARTTLS extension

I still face the same issue despite trying the solutions mentioned here: • https://community-chat.signoz.io/t/28536334/hi-all-i-need-env-for-disabled-smtp-tls-for-version-v-70 • https://signoz.io/docs/manage/administrator-guide/configuration/alertmanager/#disabling-tls-for-smtp Env passed:

SIGNOZ_ALERTMANAGER_SIGNOZ_GLOBAL_SMTP__FROM=noreply@domain.com
SIGNOZ_ALERTMANAGER_SIGNOZ_EXTERNAL_URL=<http://localhost:8080>
SIGNOZ_ALERTMANAGER_PROVIDER=signoz
SIGNOZ_ALERTMANAGER_SIGNOZ_GLOBAL_SMTP__TLS__CONFIG_INSECURE__SKIP__VERIFY=true
SIGNOZ_ALERTMANAGER_SIGNOZ_GLOBAL_SMTP__REQUIRE__TLS=false

SIGNOZ_ALERTMANAGER_SIGNOZ_GLOBAL_SMTP__SMARTHOST=<http://mail.domain.com:26|mail.domain.com:26>

Any guidance would be really helpful. Thanks in advance!
