This has nothing to do with concurrency of INCOMING smtp connections.

I don't know which software you are using, but I don't know of any
config files named
concurrencypop3 or concurrencysmtp
Check your startup scripts. There should be a line like:
/usr/local/bin/tcpserver -R -v -u 101 -g 101 -c 50 0 smtp \
/usr/local/sbin/tcpcontrol /usr/local/etc/popmgmt/etc/smtp_allow.cdb \
/var/qmail/bin/qmail-smtpd 2>&1 | /var/qmail/bin/splogger smtpd &
that starts up the tcpserver for incoming SMTP connections.
The "-c 50" limits in this case the number of concurrent tcpservers
allowed. You probably have "-c 80", change that to e.g. "-c 120".
You could do the same in the startup script that starts the qmail-pop3d
if you experience problems there, too.
