Send mail gives EmailSendException

...mail.MessagingException: Could not convert socket to TLS;
nested exception is:
          javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

where <mail@address.com> is an existing address and 192.168.1.252 is the IP of the SMTP server.

Any ideas?

Thank you in advance!

Is this property set as
conf.mailhandler.mail.smtp.starttls.enable=true

forum.appian.com/.../Mail_Server_Setup.html

thanks for your answer!
Yes, these are the properties i have set:

conf.mailhandler.mail.smtp.host=192.168.1.252
conf.suite.MAIL_SCHEME=http
conf.suite.MAIL_SERVER_AND_PORT=localhost:8080
conf.mailhandler.mail.transport.protocol=smtp
conf.mailhandler.mail.smtp.auth=false
conf.mailhandler.mail.smtp.starttls.enable=true

But it still doesn't work. Same error...

Once restart the server and then try.. It will work

....now it works. Also with (maybe better in my case since i am not using secure connection) conf.mailhandler.mail.smtp.starttls.enable=false
Thank you so much!!!! :)
