RE: Nortan Antivirus 2000 Poproxy.exe problem

[Franklin DeMatto <franklin () qDefense com>]

This was a known problem, already publicised in 1999.

Symantec fixed it, and also had POPROXY.EXE bind
to 127 so as to only accept connections from localhost.

Hi! I am having difficulty confirming this for two reasons. Perhaps I am 
doing something wrong. I am running Norton Antivirus 2000 with poproxy.exe 
on MS Outlook 2000. 
poproxy.exe SEEMS to only bind to localhost (127.0.0.1) instead of my IP on 
the network (192.168.0.24). If I try to telnet to port 110 from another 
Windows machine, it cannot connect. If I try to telnet to 127.0.0.1 from my 
own machine, it connects fine. Once I did connect to it from localhost, I 
sent 269+ chars to it and only received back "-ERR". I did not experience a 
crash. 


Again, perhaps I'm doing something wrong.
