[PROBLEM SOLVED] Hi every one. I would ask you about configuration of amavisd-new. I can't found option $max_servers in default configuration. I need increase this parameter but I dont know in which file I should add this option. I use Debian 6 with ispconfig and it is slice different from configuration on CentOS. Could anyone help me ? OK. I Added this parameter to file called 50-user in amavis/conf.d/ and it is works fine for me regards.
