We are investigating an issue where emails sent through some servers are receiving bounces such as:

From Gmail's servers:
"550 5.7.1 [] Messages missing a valid address in From: header, or having no From: header, are not accepted."

This is not only affecting emails sent to Gmail addresses and some users may experience issues with other recipient mail servers.
