How do I increase the amount of concurrent SMTP connections?

I know I found this setting once, but I can't seem to find it again.

Basically, I need to allow more active SMTP connections at once to qmail/smtp.

I think the default is 25 or something.

Does anyone know where this setting is located?
 
It's defined globally for all xinetd services in /etc/xinetd.conf

e.g.

cps = 25 30

The "25" is the maximum number of connections allowed per second (per service). If it exceeds that, it will be disabled for 30 seconds.
