SMTP connector not working

Hello,

I've using an SMTP connector in my process where I provide a username and password. SSL is disabled. In my process, a form is submitted and an email is supposed to be sent. However, it's not working. Without the authentication, email works. Currently, my SMTP server accepts open relay. However, this is changing soon so I need to provide authentication in the Bonitasoft software.

In the logs this is what I see:

AuthenticationFailedException error.

javax.mail.AuthenticationFailedException: 535 5.7.3 Authentication unsuccessful

I've performed the following steps in trying to resolve this issue:

• Reset account password
• Added windows firewall rule on server that host the Bonita application
• Turned off the windows firewall on server that host the Bonita application
• Disabled antivirus
• For username, tried the following: domain\username and username@domain.com
• Ran Send-MailMessage PowerShell scripts on server that host the Bonita application. This worked. However, sending emails from the software does not work

I'm stuck at this point. Please help me in finding a solution.

Thank you.
