to control the number of connections to MySQL you could use mrtg, at you can find the mysql "plugin", i use [mrtg-mysql-load] to 
monitor the query and slow query per minute.
remember to use qmailmrtg to monitor the qmail traffic and usage.

I think that it's very hard to reach the maximum number of (phisical)  
20-30 pop3 connections at the same time would not be a problem for 
qmail/mysql, i've constantly 100-150 (and sometimes 200) concurrent 
connection, as shown from qmailmrtg, to the pop3 and the system works good.
