At the time of configuration I specified incoming pop3, and outgoing SMTP as my exchange server.But it is not sending outside addresses. It shows an error like this for all internet addresses..but it sends and receives GAL addresses. The message could not be sent because one of the recipients was rejected by the server. The rejected e-mail address was 'xxx@xxxxxxxxx'. Subject 'test 12.42. pm', Account: 'exchserver', Server: 'exchserver', Protocol: SMTP, Server Response: '550 5.7.1 Unable to relay for xxx@xxxxxxxxx', Port: 25, Secure(SSL): No, Server Error: 550, Error Number: 0x800CCC79 In my server I am using default smtp virtual server for sending and receiving outside mails.POP3 virtual server is not yet configured. Is it necessary? Any suggestion on this ?
