The fact that the attempt is being rejected with that message means it is, indeed, the remote end. Send your mail through your ISPs relay. If you have problems with your ISPs relay, get a better ISP. I do this on my mail server, and a lot of other people refuse mail from dynamic ips ... this is an attempt to stop the _hundreds_ of spams I was getting each day. Run a real mail server, use your ISP's relay or accept that people are going to block you. Peroid. The internet is not a friendly place. I block dynamic IPs for the same reason I lock my doors at night, because if I don't people abuse my kindness. The fact that it also keeps out friendly people sometimes is something I don't like, but have to live with. -- Bill Moran Potential Technologies http://www.potentialtech.com
