  • Enforcing SSL protocols between Platform JEMAIL and SMTP server

    Posted by dcrossey on June 17, 2021 at 12:00 am

    Hey all,

    If you are using the bundled java email engine in KX Platform to send emails to an (SMTP) relay server using TLS, and you’ve recently upgraded/or the SMTP has been upgraded, and you’ve seen an error where the TLS connection cannot be established (after working previously), such as:

     

    You will need to add a new parameter to your DS_JEMAIL_SERVER config to explicitly set the SSL protocol that is accepted by your SMTP relay server.

    For example:

    mail.smtp.ssl.protocols Specifies the SSL protocols that will be enabled for SSL connections

     

    mail.smtp.ssl.protocols=TLSv1.2

    Note – I’ve redacted the from / host / trust addresses.

    After updating your configuration, remember to bounce your java email process to pick up the new configuration:

     

    You should see a similar message to this on your jemail process log after restarting:

     

    Now we can establish the TLS connection and send emails out

     

    Sample email API call:

     

    .email.send[`to`subject`body!(`$”YOURNAME@DOMAIN.COM”;”Test email”;”This is a test email”)]

    Best regards,

    David
