I used The Perfect Server - CentOS 5.3 i386 [ISPConfig 2] tutorials. its great thanks I installed phpmyadmin using the ispconfig and cubemail. Heres the issue but i have no idea where to start to find the problem and fix it. I cant send email (i do need to get rdns setup) but i can not receive emails. I send my self email using my hotmail account. but i never get them and hotmail account does not receive a delivery failure notification. Where do i start? noteissue was present before cubemail install and after) I am complete noob please make instruction step by step. thanks update: finally got a return fail email. reason says smtp;550 #5.1.0 Address rejected [email protected]
