I am using the transmission through an external SMTP. mail.mydomain.com AD Internal mydomain.local I have a user in exchange, I am testing the service before making available to all users, but this user receives e-mails from all internal and external world, uses the POP Connector downloading from a POP external okay. But this user can not send emails to the inner person, example user@mydomain.com.br, it returns saying that the recipient does not exist. Yes there is in AD, but the external field there is an account for him and it seems that the exchange is trying to find it internally. How to solve this problem?Odraude Solrac

Exchange doesn't have a POP connector. If you're using SBS, I recommend that you post to the SBS forum. If you're using a third-party POP connector, I recommend that you contact the vendor. -- Ed Crowley MVP "There are seldom good technological solutions to behavioral problems." .
