no I do not have a Cisco router I have a basic router which is provide by my ISPhere is what I have done from the CEICW on SBS 2003:1- I have the check box set for email on Service configuration2- IN create Certificate I select do not change3- As I am not using DNS to rediret my email, I have select Forwal all email to email server and I type in the mail server as : mail.solatys.com 4- Then on the Incoming mail method screen i have select to use POP3, the check use Exchange and set option in order that mails are host at my ISP side until my server send a signal. Then I enter again the server mail to send the signal to as : mail.solatys.com 5- For the type of signal I have ETRN which is set ( I do not know really here)6- The next page I have to enter my domaine name for my mail box : solatys.com Thats it for the configuration of CEICW that I have done Then next I follow the next steps as :Server Management | Advanced Management | First Organization (Exchange) |Connectors | (right click) SmallBusiness SMTP Connector | Properties |Advanced | Outbound Security | Basic Authentication | Modify. Then I enter here the login account to the provider that host my mailbox on domain solatys.comwhich is a different account as my ISP which give the outside line. Which credential should be then ?
