Hi, Somehow my virtual domains are not receiving emails in Postfix, I have looked through every step of the How to (Ubuntu with ISPConfig setup) but somehow I cannot find what I have done wrong. When I dig mx agnitio.nl I get following response ; <<>> DiG 9.4.2-P2 <<>> mx agnitio.nl ;; global options: printcmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 27158 ;; flags: qr rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 0 ;; QUESTION SECTION: ;agnitio.nl.
