It's high for a server that does things other than mail. For my purposes, it's fine. As I said before, MAXDAEMONS is used to prevent resource exhaustion. Setting it as high as I do may not prevent intentional attacks, since an attacker could raise all of the services to their max and use more than the available physical RAM. However, I'm more concerned with not setting it so low that users have login problems, as I believe that's more likely. > Thus the above is an indication of how much ram a server should have > for a given number of users. Is it fair to think of 10~15K per daemon? It depends somewhat on the size of your users' mailboxes. couriertls is probably about 500k per daemon, imapd is often as much as 5-10MB. ------------------------------------------------------------------------------ SF.Net email is Sponsored by MIX09, March 18-20, 2009 in Las Vegas, Nevada.
