Can anyone suggest if I can use outbound functionality without setting up SMTP locally on CMS server? I have mail relay service setup on some other server, by using which I can send mail from my web server. I am not able to see any configuration file in tridion where I can configure my mail relay address. Can anyone suggest the section in outboundemail.xml configuration, where I can configure my mail relay service.
The Outbound E-mail Mailer service will generate .EML files in the
<QueueFolder> location specified in the OutboundEmail.xml configuration file.
You will need something to process the .EML files - to either process and send them directly, or relay them to an email server. You could use IIS SMTP to process the .EML files (https://technet.microsoft.com/en-us/library/cc772058(v=ws.10).aspx).
