ソリューション
Since STARTTLS upgrades the connection to TLS after it has been established, the standard way of retrieving SSL certificates will not work.
Additional argument "-starttls smtp" is required in the openssl call.
openssl s_client -debug -connect mail.mycompany.com:587 -starttls smtp < /dev/null | sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p' > public.crt
jre/bin/keytool -import -alias tomcat -keystore jre/lib/security/cacerts -file public.crt
Standard certificate store password is "changeit".
Repeating this for all required certificates
