A vulnerability exists within IMail that
allows remote attackers to gain SYSTEM level
access to servers running IMail's SMTP
daemon (versions 6.06 and below). The
vulnerability stems from the IMail SMTP daemon 
not doing proper bounds checking on various input 
data that gets passed to the IMail Mailing List 
handler code. If an attacker crafts a special 
buffer and sends it to a remote IMail SMTP server 
it is possible that an attacker can remotely execute 
code (commands) on the IMail system. 

Solution:
