SSL failed to send email

No Title

Hi

I have added “camunda-bpm-mail-core” maven dependency (version 1.2.0)in pom.xml and

mail-config.properties in class path of spring boot project,

but there is an error when sending an email.

I have deployed this bpmn
mail.bpmn (3.4 KB)

Here is the mail-config.properties :

mail.transport.protocol=smtp

mail.smtp.host=smtp.gmail.com

mail.smtp.port=587

mail.smtp.auth=true

mail.smtp.ssl.enable=true

mail.smtp.socketFactory.port=465

mail.smtp.socketFactory.class=javax.net.ssl.SSLSocketFactory

mail.smtp.starttls.enable=true

poll mails via IMAPS

mail.store.protocol=imaps

mail.imaps.host=imap.gmail.com

mail.imaps.port=993

mail.imaps.timeout=10000

if peek = false then the polled mails are marked as read

#mail.imaps.peek=false

additional config

mail.poll.folder=INBOX

mail.sender=PizzaInc

#mail.sender.alias=User Inc

mail.attachment.download=false

#mail.attachment.path=attachments

credentials

mail.user=m@gmail.com

mail.password=PASSWORD

here is the error log

org.camunda.bpm.extension.mail.MailConnectorException: failed to send mail

Caused by: javax.mail.MessagingException: Could not connect to SMTP host: smtp.gmail.com, port: 587;

nested exception is:

javax.net.ssl.SSLException: Unsupported or unrecognized SSL message

Thank you all in advance.
