How can I set [output_adapter.email] with Aruba address in wso2 Identity Server v. 5.11.0? - wso2

Question

I'm trying to set an email sender (for example recovery password). I already set with a Gmail and Outlook address mail and it's work!
Now i nedd to configure an Aruba hostmail.
this is my deployment.toml configuration module
[output_adapter.email]
from_address= "****#aruba.it"
username= "*****#****.it"
password= "******"
hostname= "smtps.aruba.it"
port= 465
enable_start_tls= true
enable_authentication= true
signature = "****"
[output_adapter.email.custom_properties]
"mail.smtp.ssl.protocols"="TLSv1.2"
"mail.transport.protocol"="smtps"
Logs return
ERROR {org.wso2.carbon.event.output.adapter.email.EmailEventAdapter} - Event dropped at Output Adapter 'EmailPublisher' for tenant id '-1234', Error in message format, Could not connect to SMTP host: smtps.aruba.it, port: 465, response: -1 javax.mail.MessagingException: Could not connect to SMTP host: smtps.aruba.it, port: 465, response: -1
I tried with smpts and smpt (it should be the same port 465).
Can you tell me if it's not supported or something?
THanks, i really need help :(

I fixed it by adding these properties in deployment.toml file below this modules:
[output_adapter.email]
from_address= "***#aruba.it"
username= "****"
password= "****!"
hostname= "smtps.aruba.it"
port= 465
enable_start_tls= true
enable_authentication= true
signature = "WSO2"
[output_adapter.email.custom_properties]
"mail.smtp.ssl.protocols"="TLSv1.2"
"mail.smtp.debug"="true"
"mail.smtp.socketFactory.port"="465"
"mail.smtp.socketFactory.class"="javax.net.ssl.SSLSocketFactory"
"mail.smtp.socketFactory.fallback"="false"
