I have a server running ISPconfig with our main web page for our company on it, there are a few pages where a form is filled out and an email is sent. We moved the site off a windows box where this worked fine, but now that the site is on a local machine with the same domain name as the website, if I try to send a message through the form it never reaches the recipient, instead it sits in the Exchange 2003 deferred queue. In main.cf I made a change to the domain name and shortened the domain name and added a DNS record on the Exchange server to fix a problem from it sending mail before under a different program, but I don't remember what it was for. If I switch it back to the full domain it sends it locally instead of to our exchange server, which of course fails since the mailbox user doesn't exist locally. What can I do so that any and all mail sent on this box goes to the Exchange server? Also any idea on why the ones that are sent sit in deferred queue?
