Hi all my problem is that: starting ISPConfig I tried to configure some domain and then I deleted them. i.e. my server is under the domain: www.main.it and during the activation, I defined an alias such as main.it and deleted it. Now when I try to send an email (i.e. using PHP function mail()) doesn't start because when I create a new site ISPConfig rewrites the file: /etc/postfix/local-host-names this file contains the host-names deteled before. Then Postfix attempts to send an email to my server believing that the domain 'main.it' is managed locally. I discovered that if I erase all definitions in local-host-names ISPConfig rewrites the data fetched from Mysql ISPConfig db. I don't know how ISPConfig db works because I've not studied the relations between tables, then I can't delete manually these records. Could someone help me?!? Thank you very much.....
Never delete records in the ISPConfig DB manually if you dont want to corrupt your installation. Did you empty the recycle bin?
