For 2 weeks I've tried setting up my own email system. I'm so confused. I have no idea how this stuff works.. I tried to read some tutorials, but they only explain how to setup up the actual email server (and that isn't even the hard part here).



I want people to be able to use the lost password function, send out newsletter and those stuff. The PHP scripts for that is already covered. The question is how do I make the email system work? What DNS settings to use? Try to get the whole picture right for me.



What I want to do:

Being able to use the domain "tibiahelp.com" to send out emails to the users.



What I have done so far:

All necessary ports are unblocked.

Configured the email server (Mercury) as following:









The DNS settings:

tibiahelp.com MX dns is set to 85.227.190.37 (IP where email server is hosted)



When I try to send an email from jontz@tibiahelp.com, this is what I get:

Temporary error 249 (temporary MX resolution error) resolving 'hotmail'.com'.



Thanks!
