I would like to add my two cents here. I recently discovered that I could send mail from home to my account at work using a sender name of an IMail alias! I did another test with a completely nonexistent address and the mail was delivered! I did this using MS Entourage for MacOS X. I tried the same with MS OE on a W2K box and it would not allow me to send mail. The difference between these configs was in Entourage I set no POP3 server (actually I was able to send the mail with a POP3 address entered as well), OE would not let me leave the POP3 address empty. Our IMail server is currently 7.07 with 'Relay mail for' (6 subnets), 'Check for valid sender' and 'Disable SMTP VRFY command' are checked. 'Disable SMTP AUTH command' is not checked. I had someone telnet (from outside my network) into the SMTP port and enter in raw SMTP commands to send mail to another user on our server and it came through. He used a completely made up username and domain. But I believe this maybe normal behavior for SMTP implementations (I've not read the RFC's for SMTP).
