An SSL certificate was updated on the email server but this certificate was not updated on the Appian side.
Update the certificate in Appian by importing into the trusted keystore of the JDK.
Run the following commands to import the certificates into the Java Keystore:
cd <JAVA_HOME>/bin
keytool -import -alias <webserver.example.com> -file <CERT_NAME>.crt -keystore "<JAVA_HOME>/jre/lib/security/cacerts"
This article applies to all versions of Appian.
