Hi all, First of all, sorry my english is very bad. I using IspConfig, severeal years. I have it on production and love it. It's impressive control panel. I have two questions: 1) Configure outbound relay per domain I configure my relay options on System > Server Config > Mail > Relay Host. It work's perfect. But I want to exclude a domain, or domains. For example: - domain.com use localhost - domaintwo.com use smtpaux.coolrelayserver.com - all other domains use ispconfig relay options. This is possible? 2) Custom dovecot options I installed Rspamd on my Ispconfig3 servers. It works very nice, but need some changes in /etc/postfix/main.cf and /etc/postfix/dovecot.conf. I lost changes when upgrade Ispconfig panel. Which would be a good practice for custom configurations in this files? Thanks alot for your time!
