Almost certainly this is a limits issue. If you can, it's easy to find
out the limits by temporarily running /usr/bin/limits instead of
qmail-pop3d.
Where you have:
tcpserver ..... qmail-popup example.com /bin/checkpassword /var/qmail/bin/qmail-pop3d
Maildir
Change it to
tcpserver ..... qmail-popup example.com /bin/checkpassword /usr/bin/limits -a
and capture the output of a telnet test to your pop account.
Alternatively, if you're comfortable with tcpserver etc, run another
instance on another port so as not to disrupt the existing pop usage.
Regards.
