Number of smtp connections

[Pascal Maes]

hello,


In master.cf, I have

smtp  inet  n   -   n   -   100   smtpd


Is there a way to measure the number of connections to see how many  
times the limit is reached ?



Thanks

Postfix logs a warning once the limit is reached

Postfix will log a warning when the limit is reached.  If this 
happens frequently, you should increase the process limit.

http://www.postfix.org/TUNING_README.html#proc_limit

You can measure the current number of connections using system 
tools such as netstat or lsof.

A simple-minded example:
# lsof -n -i :25 | nl

Also very relevant is http://www.postfix.org/STRESS_README.html
