Ok, so I have a small php script that sends an confirmation email after signup.. but it isn't working.. I know it isn't the code as the script works any where else, but I have made sure sendmail is installed, as well as checked my php.ini file.. The thing is, if an email is sent from 1 local email to another it will work, but it wont work sending to outside website providers.. here is an image of what I mean.
Hopefully that can help.. I was using dovecot but just switched it over to Courier i didn't know if it would solve the problem, but I can see now it didn't :/
Here is a link to a paste of my maillog. http://pastebin.com/QsZq9RbR
Also I did find a log named maillog-20121216 so i opened it up and it has this, which isn't in the pastebin post
