Collaborators invite mail not sent with Mailjet configuration

I am using Mailjet credentials for sent mail from twake. I refered and following steps from you mail configuration tutorial
I attached my config below
“sender” => [
“host” => “”,
“port” => “25”,
“username” => “45*********************”,
“password” => “5c**********************”,
“auth_mode” => “plain”
But mail not sent successfully also all member will add in pending Members tab. At the same time I checked Nework tab in chrome developer tools while click Add button, my server call /ajax/workspace/members/addlist route but your will sent data to ajax/users/console/api/invite route. I don’t what is the problem in my configuration. Could you please check and let me know what is the issue for my configuration.

Thanks for advance
