Hello, i updated to the latest version (ceontos 7) now greylisting was changed in the postfix configuration from greylisting = check_policy_service unixostgrey/socket to greylisting = check_policy_service inet:127.0.0.1:10023 why is that changed? and better how can i prevent that this happen in the future
This has not been changed. Probably you configured it manually before in a different way. ISPconfig is and was always using port 10023
To make your customizations update safe, put them in /usr/local/ispconfig/server/conf-custom/install/postfix_custom.conf.master
