Google wants your smtp_helo_name (default: $myhostname) to have an SPF
policy.
Options:
- Create an SPF policy for the SMTP helo name that permits the
corresponding SMTP client IP address.
- Create a wild-card SPF policy for *.raystedman.org that permits
all your SMTP client IP addresses.
- Change the smtp_helo_name to a name that already has an SPF policy.
This is messy because the name should match the PTR record for the
SMTP client IP address.
