```
**however** I'm still testing as on another environment the same setup (I'm using the same docker image) doesn't seem to complain about such an _invalid_ config (trouble is on this other environment I don't have access to the smtp server causing me trouble).
Is there any setting to disable elasticsearch configuration validation so I can test on the environment with access to the smtp server using the invalid certificate?
can you think of any reason why apparently the same setup would throw such exception on one environment and not the other?
thanks again,
H

The config option [reintroduced in 6.3.2](https://www.elastic.co/guide/en/elasticsearch/reference/6.3/release-notes-6.3.2.html#bug-6.3.2) should be:
```auto
xpack.notification.email.account.smtp.ssl.trust
```
in the same manner as you'd set any other [watcher email notification settings](https://www.elastic.co/guide/en/elasticsearch/reference/6.3/notification-settings.html#email-notification-settings).

No, not really.

No, again, not really. I'd check if the config keys are the same and if the extra config key is indeed added to the configuration file. Are both environments using the same Elasticsearch version?

thanks Ioannis, I have a bit more information now.
The difference between the working/failing environment was not the elasticsearch.yml file but an **environment property**.
As soon as I have an environment property with name "mail.smtp.ssl.trust", elastic won't start.
At least now I have elastic up and running again. Sorry for the confusion before.
Regarding the config option reintroduced, can you please clarify where should this be setup?
At the email account level in elasticsearch.yml?
Would this be the correct way? I'm using environment properties for all values.
```auto
xpack.notification.email.account:
myaccount:
email_defaults:
from: ${ES_FROM_EMAIL}
smtp:
auth: ${ES_SMTP_AUTH}
starttls.enable: ${ES_SMTP_STARTTLSENABLE}
starttls.required: ${ES_SMTP_STARTTLSREQUIRED}
host: ${ES_SMTP_HOST}
port: ${ES_SMTP_PORT}
user: ${ES_SMTP_USER}
ssl.trust: ${ES_SMTP_HOST}
password: ${ES_SMTP_PASSWORD}
```
thanks,
H

answering my own question, I can confirm the format above works for me and I was able to successfully get an email sent through that smtp server.
thanks again Ioannis for your support!

You're most welcome. FYI, I opened [https://github.com/elastic/elasticsearch/pull/34275](https://github.com/elastic/elasticsearch/pull/34275) to fix the missing documentation
