Dears,

ELK in version: 7.16

I want to test and deploy email notification in Kibana. During configuration of email connector I've got error message like this:

```auto
{"type":"log","@timestamp":"2022-05-17T08:51:18+02:00","tags":["warning","plugins","actions"],"pid":1283,"message":"action execution failure: .email:e1c91f90-d5a4-11ec-b6b5-cd23b20498cd: MailConnector: error sending email: unable to verify the first certificate"}
{"type":"log","@timestamp":"2022-05-17T08:51:50+02:00","tags":["warning","plugins","actions"],"pid":1283,"message":"action execution failure: .email:3a7bf564-0d3d-440b-baab-859289d0a9e7: ITCSMTP: error sending email: 139950185228224:error:1408F10B:SSL routines:ssl3_get_record:wrong version number:../deps/openssl/openssl/ssl/record/ssl3_record.c:332:\n"}

```

my Kibana configuration file:

```auto
server.port: 5601

server.host: "192.168.1.120"
server.publicBaseUrl: "https://192.168.1.120"

server.name: "Kibana"

elasticsearch.hosts: ["https://elastic01:9200", "https://elastic02:9200", "https://elastic03:9200"]

server.ssl.enabled: true

server.ssl.certificate: /etc/kibana/certs/kibana.crt

server.ssl.key: /etc/kibana/certs/kibana.key

elasticsearch.ssl.certificateAuthorities: ["/etc/kibana/certs/ca.crt"]

elasticsearch.ssl.verificationMode: full

logging.dest: /var/log/kibana/kibana.log

logging.rotate:
   enabled: true
   everyBytes: 10485760
   keepFiles: 10

xpack.encryptedSavedObjects.encryptionKey: 9620034d3aecbb422b189c5b181d5f93

```

Do you have any experience with email connector configuration and such errors?

Best Regards,  
Dan

This is my configuration in Kibana:

 ![ec1](https://us1.discourse-cdn.com/elastic/original/3X/6/1/610a529dd10476eee31ee4d04763afe71de81d88.jpeg)

and error which show during test:

 ![ec2](https://us1.discourse-cdn.com/elastic/original/3X/9/a/9a9cbeecc468e396320ffa221a5e76f7cf445ce8.jpeg)

Kibana log show:

```auto

```

test smtp auth without SSL:

```auto

additional configuration in kibana.yml file solve this issue:

```auto
xpack.actions.customHostSettings:
  - url: smtp://A.B.C.20
    smtp:
      ignoreTLS: true

```

Any idea why configuration directly from Kibana does not work?
