All,
I am getting spam email with return-path of my domain name, but:
Received: from friend (dsl-201-135-40-163.prod-infinitum.com.mx
<http://dsl-201-135-40-163.prod-infinitum.com.mx> [201.135.40.163
<http://201.135.40.163>] (may be forged))
Three letters. SPF.
Publish a SPF record for your domain, and enable the SPF plugin.
After that all mail forging your domain, or any other SPF domain, will get
penalized SPF_FAIL or SPF_SOFTFAIL (depending on what your "all" record looks
like).
Even better ..... get your MTA to reject spoofed messages with your
domain !!!
