SMTP connection issue on Wildfly 15 using TSL 1.2


Article ID: 224042


Updated On:


CA Identity Manager CA Identity Suite


Customer changed the SMTP provider and the notification email doesn't work on Identity Manager.

The new SMTP provider requires TSL 1.2 version.

The current version of Identity Manager is 14.4 installed on Windows 2019  with Wildfly 15.0.1

Following the techdoc below we enabled the tls for mail server but is not possible to explicit the protocol version 1.2



Release : 14.x

Component : Identity Manager


Standalone-full.xml / Standalone-full-ha.xml can have different configuration parameters.

While some configuration would work with

<smtp-server outbound-socket-binding-ref="mail-smtp" 
tls="true" >
Others would work better with
<smtp-server outbound-socket-binding-ref="mail-smtp" ssl="true" >
So both should be attempted, when secure communication to the SMTP server is required.
Red Hat Support would be able to provide additional / specific information per use case.
