Hi Chris,
My POP3 parameters are
# qpopper config file for xinetd
service pop-3
{
flags = REUSE NAMEINARGS
socket_type = stream
protocol = tcp
wait = no
user = root
server = /usr/sbin/in.qpopper
server_args = in.qpopper -s
disable = yes
instances = 80
}
As you can see, uits set to instances=80. I can change that to 100,
and do I just enter a new line
cps = 100 10
And how/where do I do this
"The in.qpopper command line should have -R as option"
And telnet as you suggested comes back with
+OK AVG POP3 Proxy Server 7.1.371/7.1.394 [268.10.7/410]
Not sure what that means as we do not have a proxy server ?
Rgds.

Hello whoever,
there may be several reasons.
Have a look at
/etc/xinetd.d/pop3
a) Is the
cps
parameter set?
Set it to say
cps = 100 10
b) Is the
instances
parameter set?
In case it is, set it to
instances = 100
c) The in.qpopper command line should have -R as option
In case the system gets stuck: can you track a pop3 query? Does the pop3
protocol start and gets stuck at the authentication? Or ist the no
response to pop3 request at all? Try
telnet host_in_question 110
is there any answer?
Regards,
Chris
