Hi guys, After some unsuccessfull tinkering on my part, I ended up having to reinstall Postfix on the Ubuntu 12.04 server with ISPConfig 3 installed. For many months everything has been working fine, but some time ago, I don't know exactly when, unfortunately, my mail server stopped receiving messages. Sending works fine. So right now a friend of mine established that the mailbox accounts I had set up in ISPConfig do not appear to be recognised by Postfix. I.e. the mail I'm using to send the messages receives a MAILER-DAEMON error email saying that the email had not been found in the system. I don't know what I have screwed up, the old config files were not touched (*much* ). Could you please help me figure a way out of this? Thank you!

I just added this test@ account and tried sending an email to it from an outside mail. EDIT: Nevermind, found the culprit.
