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
