Send Mail - Obfuscate Connection Details

Hello

Is there any way to “obfuscate” the SMTP connection details for the mail node?

Our IT doesn’t want to give out the details (I’m working on that, not seeing an big safety issue there).

I’m making a workflow that I’d like to send an email only if the report comes up non-empty so I’d need to send the mail from within the workflow and not use the mail function that runs when the workflow completed.

Thanks
