Report external user to Fraud department

[David270778645e3e]

I'm receiving emails from external person that I don't know to sign through adobe sign however this document is malicious and I need to block the user.

I can't block the source as it is adobesign@adobesign.com and we receive many of them through the email server.  

How do I block a single user from sending to my company?

Contact your IT department - they should be able to block an individual email account from your servers.
