SMTP Return Path
I just discovered the ColdFusion "failto" parameter for the cfmail tag, our new web host requires that this be set for some anti-spam feature.
Anyway, I did some research on this, I can't figure out if this is generally respected by email clients or servers.
I wonder if this would be useful in other environments beside ColdFusion.
The best, clear, reference that I could find:
