I don't think this is about relaying. Spoofing a from-address can be done without any relay at all. I just found this out. I had been getting strange entries in my maillog from sourceforge servers, and their admins told me it had to do with SMTP callback. i.e. finding out if the from-address is valid or not. I think this is what's required. But it has nothing to do with relaying, I'm *almost* certain :). On Friday 08 June 2001 16:04, Leah Cunningham wrote:

You need to disable relaying in sendmail. I'm not positive where this is, but I imagine someone else here can tell you, or you could look it up, that's what I ususally do. I thought's SuSE's sendmail.cf took care of this by default, but I don't remember.
