Hello all,
I'm a beginner in JavaMail, I have several question, can I use following case:
SMTP + TLS + Authentication
SMTP + TLS + without Authentication
SMTP + Authentication + without TLS
and
SMTP + SSL + TLS + Authentication
SMTP + SSL + TLS + without Authentication
SMTP + SSL + Authentication + without TLS
Because I have the following code, it's correctly work for send a mail with returned Transporter, but no with SMTP only, SMTP + SSL, SMTP + SSL + TLS.
I have the following exception for example:
javax.mail.MessagingException: Exception reading response;
nested exception is:
javax.net.ssl.SSLException: Unrecognized SSL message, plaintext connection?
Can you give me use properties and means to correctly use SSL and TLS ?
Great thank !
Best regards
Adryen
