I was reading through this thread about reply-to since I was noticing odd behavior of the mail sent in my workflow.
It sounds like it should be sending from something short like noreply but my mails sender looks like this:
Is there no way to get a cleaner sender of emails?
Hey @khill-fbmc - I've only tested with the Gmail web client, in which case it's significantly less obnoxious. Are you using Outlook or something similar?
While it is possible to specify a list of reply-to emails, there's not currently a way to modify the sender. Not even via Enterprise white-labeling, interestingly. 
If you want full control, it's probably necessary to configure a dedicated SMTP resource.
Yes, unfortunately we must use Outlook, not by my choice 
I was thinking about trying the Microsoft Graph and seeing if that could send email on behalf of a user.
It's definitely worth a shot, if your org is already hooked into the MS ecosystem! And doubly so if you have experience hitting the Graph REST API. 
Did you ever try out the MS Graph API, @khill-fbmc?
I have not tried to use it directly to send emails yet. I keep getting pulled all which way 
Ah I get that. 
No worries and no rush - I just wanted to check in.
I'll go ahead and mark my above response as the "Solution", then, but don't hesitate to reach out if or when you want to revisit this.
