This did not help us,
We are now seeing log messages that read
Berkeley db /etc/sasldb2: No such file or directory Apr 18 16:50:46 admin
sendmail[2389]: unable to open Berkeley db /etc/sasldb2: No such file or
directory
Not sure they are related did not appear before, they seem to be harmless,
we lowered again out pop limit to default 80
And wait for tomorrow storm removed 100 accounts of email, however raq 550
could handle this without problems.
We did notice the Increase in TCP connections it went from 250 to 600 during
the stress time, 300 of which were suppoesed to be port 110 connections.
Hope this helps to give clues.

Ok,
This is the status:
As I couldn't recompile qpopper due to I don't know where is, I made the
modifications suggested by patricko (at mark) staff.singnet.com.sg, that is modify
/etc/xinetd.d/pop3 & /etc/pam.d/pop3.
In /etc/xinetd.d/pop3
# qpopper config file for xinetd
service pop-3
{
disable = no
flags = REUSE NAMEINARGS
socket_type = stream
protocol = tcp
wait = no
user = root
server = /usr/sbin/in.qpopper
server_args = in.qpopper -R -S
instances = 1024
}
And we increase the instances to 1024, just even if we go to 9999 as someone
said, when we restart the system, they put that back to 1024. Also, if you
go the the BlueQuartz GUI you cannot go above 1024. patricko proposs to
include also the -s on server_args but that one doesn't work.
Now, the one that really make the difference was the /etc/pam.d/pop3
As soon as we modify that one, everything went back to normal and fast.
#%PAM-1.0
auth requisite /lib/security/pam_nologin.so
auth requisite /lib/security/pam_shells.so
#auth required /lib/security/pam_pwdb.so shadow nullok
#account required /lib/security/pam_pwdb.so
auth required /lib/security/pam_stack.so service=system-auth
account required /lib/security/pam_stack.so service=system-auth
We're going to wait a couple of days to see how this works now.
Thanks, however any info about how to migrate to something else is going to
be appretiate, just it looks that for a lot of people this is not enough.
We have about 700 users at this time on e-mails account.
Thanks,

Hi Carlos
this has been discussed several times on the list.
My guess (as genius) is that qpopper working via xinetd is too slow to
handle too much load (or too few).
I ended by compiling and installing dovecot as suggested on this list
previously and this nightmare went away finally.
It is really annoying indeed.
Is there anything else I can help you?
regards
