Guys I need your suggestion/help regarding my issue.
Here is the Scenario:
My client using POP3 services from their parent company but they want exchange server so I deploy SBS11 with the same domain name (abc.com). I configure “POPcon™ Exchange POP3 Connector” to connect Exchange server to their internet mailboxes.Everything is working fine but I have one issue.
email@example.com is user of SBS11 (Mailbox) and parent company (POP3 account).
firstname.lastname@example.org is a user of parent company (POP3 account) but NO mailbox on SBS11.
Now the situation is when I am going to send an email from Shoaib to Paul, exchange server try to find the mailbox within database but obviously there is no mailbox for Paul so I receive the NDR (The e-mail address you entered couldn't be found)
My Question is how I can tell the exchange server to first check mailbox in exchange server database if there is no mailbox related to email address than transfer that email to internet.
I think I need to create another send connector or something but I have no idea how to achieve this. Can anyone help me to resolve this problem?
