I have gotten to the point that the keystore used by the jetty application is properly configured:
JAVA_VERSION="12" java -Djavax.net.ssl.trustStore=/opt/idempiere/idempiere-server/jettyhome/etc/keystore -Djavax.net.ssl.trustStorePassword=testing SSLPoke mx32.harte-lyne.ca 465 Successfully connected This means that the server's certificate is properly recognized by the client host. However, we nonetheless get this error from Postfix when we send a test email through the application: Dec 21 12:25:21 mx32 postfix-p25/smtpd[62565]: warning: TLS library problem: error:14094416:SSL routines:ssl3_read_bytes:sslv3 alert certificate unknown:/usr/src/crypto/openssl/ssl/record/rec_layer_s3.c:1544:SSL alert number 46: Dec 21 12:25:21 mx32 postfix-p25/smtpd[62565]: lost connection after STARTTLS from accounting-2.internal.harte-lyne.ca[192.168.216.88] I believe that this is telling me that the application is attempting to establish an SSL connection using STARTTLS. However, the error referencing the certificate is mystifying to me. Can someone explain to me what this error means? -- *** e-Mail is NOT a SECURE channel *** Do NOT transmit sensitive data via e-Mail Unencrypted messages have no legal claim to privacy Do NOT open attachments nor follow links sent by e-Mail James B.
