For some users alone (i will specify them in a seperate text file) i dont want to authenticate the sender. For example a...@x.com should provide password for sending mail. Whereas b...@x.com need not provide password for sending mail. Unless b...@x.com is restricted by some means, this could be dangerous. If the restriction is for example that the be allowed to send with no pass and/or auth, but must be within the local submet, it becomes more safe.  Restriction by ip address would be another. Though both are dangerous in my opinion. With no restrictions I believe each address will be a ticking time bomb, eventually to be discovered by spammers and their scanning and attacking tools.  I'm curious what your reasons are for wanting to do this.   --  Scott Iphone says hello.
