How to debug mail using another SMTP gateway

I'm using malign as my external email gateway.   I've put in all the info but when I look at their console I'm not seeing jot forms even attempting to login and send email.  Is there a log of something I can look at ?

Please make sure that your Email Notification / Autoresponder is configured to use your SMTP sender.

To do a test, please submit a real form entry. The 'Test Email' button will not use the SMTP sender.

This is not possible to check the full email logs, but you can check the account email history. When the SMTP sender is used it should be reflected in a From: field.
