Many e-commerce sites do this type of stuff improperly. They should use an address from their site as the from with the reply-to header for where you ar to reply to. > > Also, some of my own customers are blocked by their ISP's from using my > mail server for SMTP, which means that if I configured SPF strictly for > their domains, they would fail this test wherever implemented. You could setup port forwarding for the users that are blocked so their mail goes out your server. So instead of using port 25 to send mail they could use port 925 for example. The ISP probably is not blocking this. > > If you opt to use SPF on your system, take advantage of the weighting > capabilities of Declude, and I would suggest at most being very cautious > about how much weight you give it. > > Matt > > > > Lyndon Eaton wrote: > > >That's a real shame!
