Thanks josby for your comment
But josby it is not that easy as you are describing.Can you tell me even a single smtp mail server that is ready to accept all those smtp commands without those annoying errors "relaying denied" etc .The main problem comes up as soon as one issues the "rcpt to" commmand.

I am trying to tell people at this site that I am not trying to write a tutorial on this or that.I am just pointing out the bug which i have found in the Eudora and nothing else.
