Email do multiple users


I’ve set up a task to send email to a group of people. When I add multiple recipients, I get an “Internal Server Error” error.

I’m using commas as a separator (as the Flowable documentation says), but I’ve also used a semicolon. The result is the same.

Can anyone help me solve this problem?

Thanks in advance,


Hi Michael,

Can you share the stack trace of the error?

Best regards,


Hi @tijs,

Thanks for the answer.

I’ve seen where the problem is. The email server I’m using does not allow sending emails to multiple recipients.

Thanks again,
