No thats fine. I do the same myself. It is common practice for mail servers to do reverse DNS lookups to make sure the hostname in the header matches the IP address the mail came from. Using your ISP as a relay will make sure that works. As far as your ISP is concerned it is the same as if your client connected directly to their SMTP server. derek -- ---------------------------------- www.jennings.homelinux.net
