2010 on Windows Server 2008 R2 to receive emails from the internet following the danscourses tutorials:

i don't have any windows administration skills, and i am stuck with the DNS configuration.
and the following are my domain configuration i got from the hosting.
following are the steps i made:
1- Add new name server:
add ns1.centors.com
ip Exchange Server Public IP: 41.233.26.131
2- Change the A record
change it to point to the public ip address Exchange Server Public IP: 41.233.26.131
3- New cname record for www
and make it resolve to centors.com
4- New mx record for mail.centors.com
5- New A record for mail.centors.com:
name: mail
ip: Exchange Server Public IP: 41.233.26.131
6- new A record for ns1:
ip: Exchange Server Public IP: 41.233.26.131
7- i made port forward in the router for SMTP and POP3 to the exchange server local ip address.
ISSUE: i have a user account in the active directory, and the user is member of the domain, the user is
[email protected] and when trying to login with this account in outlook
2010 on other machine using following data:
account type: POP3
incoming mail server: mail.centors.com
outgoing mail server: mail.centors.com
i always get the error: Authorization failed, check your server settings.
please advise what's wrong with the configuration, thanks in advance.
