Parked Domains: Should all parked domains have spam blocks via SPF records?

[JuniperPark]

I just added the following SPF record to all my parked domains:
TXT v=spf1 -all

It's easy to do with any registrar with a bulk edit.

What does it do? It stops most SMTP servers from SENDING email with a forged header from one of my parked domains. Most spam is sent from forged email addresses, then the domain gets blacklisted for spam even when they had nothing to do with it. Worse, the bounced email may come to YOUR mailbox.


Then I started thinking -- shouldn't this be the automatic setup for ALL PPC companies?

Thanks JP, great advice.

Why not tell them? I won't be surprised, though, if they haven't factored that
into their business plans.

This is a good idea. I do not put any MX record for my parked domains and block smtp and pop ports. This is one fine step more.
