Dear all,
I have a strange problem connecting to my mail relay server using smtps. I am currently using the following Destination definition for the connection:
#mail.password=<< Existing password removed on Export >> # #Wed Mar 18 13:11:32 UTC 2015 Type=MAIL mail.description=send notification mails mail.user=/*here's the user name*/ mail.smtp.ssl.enable=true mail.transport.protocol=smtps Name=outbound_mail mail.smtps.host=smtp.strato.de mail.smtps.port=465 mail.smtps.auth=true
This is the code I am using to connect to the server:
if (mailTransport == null) { try { InitialContext mailCtx = new InitialContext(); logger.debug("Looking up Context java:comp/env/mail/{}", jndiMailName); mailSession = (Session) mailCtx .lookup("java:comp/env/mail/" + jndiMailName); mailTransport = mailSession.getTransport(); } catch (NamingException | MessagingException e) { logger.error(e.getMessage(), e); }
}
...
mailTransport.connect();
//prepare the mimeMessage
mailTransport.sendMessage(mimeMessage, mimeMessage.getAllRecipients());I am pretty sure that this already worked out of the box. Somehow since some months it fails with the following Exception:

These are teh steps Itried to solve the problem until now:
- Add "mail.smtps.ssl.trust" with the value * to the destination properties
- Add the certificate of the server to the application (maybe it's the wrong place?):
