do i go in and edit master.cf and increase this limit or is there a better alternative?
May 25 20:57:44 server1 postfix/master[1219]: warning: service “smtp” (25) has reached its process limit “2”: new clients may experience noticeable delays

I assume the following is the line i need to alter (change from 2 to say 10?)
2 is too low a value for SMTP process limit. You could put it to 10 even on low memory systems and 100 on systems with 4GB RAM.
With Max number of Postfix child processes (under Webmin >> Servers >> Postfix >> General Resource Control) set to 10 you will continue to receive process limit warnings if the number of simultaneous SMTP users exceeds that number.
Increasing Max number of Postfix child processes will use more memory and other resources, so you must be careful. Also see http://www.postfix.org/STRESS_README.html
The default is -, which uses the compiled in default of 100. Nobody needs to care about this setting. You’re just making work for yourself, randomly changing things.
this server has been in operation for more than a year…i dont recall that i ever did change smtp defaults.
more than likely it has happened because i have copy and pasted that line from somewhere at some point in the past.
i will change it anyway…i dont usually provide email for clients…that is something that is relatively new for me (and probably why i had it set low.)
