Only on the two IP addresses I specifically identified.  Nothing on any other IP address.

Is there something in the CGP Log? When CGP cannot allocate a  
listener, it tries again and again (about every minute I think) and  
writes it into the log. Set a filter fo 'SYSTEM' when looking into the  
logfile. Maybe you have to raise the log level on the General page.

Right - that is exactly what I get (except many lines of this since  
there are many processes running).  Keep in mind, it's working fine  
as long as I put in each IP address individually into the smtp  
listener page.  So port 25 is working for CGPro.

Well something is probably listening on port 25,
fuser -uvn tcp 25
Should give you something like this
25/tcp:              root      27191 F.... (root)CGServer

Bill -
No, I shut down Sendmail.  When I grepped like you said I only saw  
the two IPs I specifically put in - none of the other 10 that  
should be in the list.
Thanks - Jack

Is there something else listening on port 25 on one of your  
addresses? Typically, Linux distro's have sendmail starting on port 25 to handle local mail. With CG shutdown, run  
"netstat -an | grep :25" (without the quotes) and see if anything  
is returned. If you see a line like:
tcp        0      0        *                   LISTEN
then you have something already listening on one of the  
addresses. Shut this service down and you should be good to go.
Hope this helps.

I started going to Windows Server 2003 and got cold feet and am  
going back to Linux.  However, even though my smtp listener is  
set to "all addresses" on port 25 it really isn't listening.  If  
I individually set the IP addresses in there they work fine.
Why can't I set it to all addresses?
Incidently, my Windows Server running 5.0.14 does not have this
