Because my laptop might send mail from just about anwhere, I've had to configure the SPF in my DNS to say that legitimate mail from my domain might come from anywere. This does not help in the slightest to isolate legitimate mail from my domain from "joe job" mail.
Ideally, you would send email from your laptop through another SMTP server that you authenticate with.
From the SPF FAQ:
Can I run an SMTP server on my laptop? If you run a personal domain, you can either not publish SPF records at all, or set up "v=spf1 ?all" for your domain, and you'll be able to send mail from your laptop no matter where you are. A better solution would be to set up your own smtp server that accepts mail from your laptop through POP-before-SMTP or SASL AUTH, so that you can still publish a more restrictive spf record. If you are the customer of an ISP that publishes SPF records, your ISP should provide you with an SMTP server that you can authenticate to, using either POP-before-SMTP or SASL AUTH. Or you can ask them to exclude you from SPF using a user-specific "exists" mechanism. -- Vince Valenti Enterprise Systems Administrator High Desert Education Service District
