Senaka, the exception may give a clue:
"
Caused by: javax.mail.MessagingException: Can't send command to SMTP
host;
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"

Hi all,
I get this exception when trying to send messages using the mail
transport. Wonder whether someone knows how to fix this. I have
followed the instructions in [1] in setting up the sender (with my
gmail account details). I have also setup gmail to use smtp/pop etc.
Thanks,
Senaka
