My customer is asking me to use SMTP with STARTTLS activated but when i do, i have the following error :
SMTP server : Connection Failed. javax.mail.MessagingException: Could not
convert socket to TLS; nested exception is:
PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException:
unable to find valid certification path to requested target
I believe it's due to the fact that they have their own Certificate Authority so i need to import root certificates in a truststore or a keystore but i don't know where it is located.
Could you please advise?
The build number is 14420.
Thank you in advance
