How to block *Spoofed* email addressed

[joshua.martin]

Hello,

someone outside of our domain is spoofing our WebMaster address and sending spam to everyone. is there a way to make a rule on Proxmox to block webmaster@blank.com from sending to itself?

(block webmaster@mycompany.com from sending to webmaster@mycompany.com)

We are using v2.5, and PFSense as our Firewall.

thank you,

did you publish a SPF record (see http://www.openspf.org/)?

Tom,

We did not register. We will try openSPF and see if that helps us out.

thanks,
