Presently, I am with a company that is using Imail 6.06 with all patches updated. Here in the near future we planning implementing a Anti-Spam/Virus Gateway using Declude etc. In the meantime, we have taken a number of steps to make sure that no one can send mail remotely off of the server. For the most part, it has worked very well, however a user with the sending address of "<>" is always able to send mail off the server. We have
 
1.) Refuse Null Sender box checked
2.) a <> enrty in the kill file
3.) All patches
4.) All boxes checked in SMTP Security Tab  
 
 
    No matter what we do, besides going over the log files, and blocking IP's has worked.
Any ideas?
 
Thanks and Regards,
