Hello,  
  
  
  
when Mailjet ist set in the email settings, the connection test and the test email work fine. Even regular segment mails are sent.  
  
  
  
But when Mautic wants to send trigger emails via capaign, I get an error email via Cron Daemon:

Quote:

**Subject: Cron /usr/local/bin/softlimit -m 150000000 -o 200 -p 80 -t 180 /usr/local/pd-admin2/bin/php-7.0-cli /home/xxxxxxxxx/go/app/console mautic:campaigns:trigger \> /dev/null**

error:14090086:SSL routines:ssl3\_get\_server\_certificate:certificate verify failed in /home/xxxxxxxxx/go/vendor/swiftmailer/swiftmailer/lib/classes/Swift/Transport/StreamBuffer.php on line 95

  
This is the line 95 from StreamBuffer.php, mentioned above:

Quote:

return stream\_socket\_enable\_crypto($this-\>\_stream, true, STREAM\_CRYPTO\_METHOD\_TLS\_CLIENT);

  
This I have found in the log file:

Quote:

Now I have a little workaround: After changing the email service from “Mailjet” to “Other SMTP-Server” and adding the correct SMTP server it now works, when encryption is deactivated (because this can only be deactivated for “Other SMTP-Server”).
