Let me explain my email server scenario first:
1, 2003 server with Mdaemon 10.0 installed and running perfectly with many restricted user accounts that can not send and receive emails to and from external network.
Couple of accounts (managers and IT persons) who can send and receive emails to and from external network using either the world client or their outlook, but all the users connected to the LAN and using mdaemon servers IP address as their POP3 and SMTP. (As usual practice).
We have a website hosted and 6 email accounts I have created on the website that is also configured on my Mdaemon server to collect pop3 emails from that web accounts and redirect to the same email a/c I have created on the local server.
One of the new hired manager got his laptop and wants to configure his email a/c on his laptops outlook (no problem) but physically he is like continuously on the go and do not want his laptop to connect to the office LAN. The problem is I did make his a/c on our website (e.g. email@example.com) that has the POP3 and SMTP as mail.ourdomain.com (both the same) as this user is not on our LAN so Im using this in his outlook.
This user can send email to any network whether it is Yahoo or Gmail or our network e.g. firstname.lastname@example.org and can receive emails from any external network EXCEPT ourdomain.com.
I havent created his a/c on my Mdaemon server as this user does not reside in our LAN, but when I see someone emailing him from our LAN (email@example.com ), all the emails are queuing in the local que and dumping into the BAD QUE means none of the email to his a/c making out to his web based email account e.g. firstname.lastname@example.org.
OK, I have created his a/c on the local Mdaemon database and put checked on MultiPOP and then configured his MultiPOP, from then all the emails are dumping into his local folder as expected.
Just FYI, I havent used DomainPOP and not know whether this is the solution for my problem or not.
Any onther thing if any expert want to ask..please let me know, I have to resolve this issue ASAP.
