how to configure receiver communication channel in File to mail scenario?

Hi all,

I'm working in FIle-to-Mail Scenario. I did all the required configuration In Integration repository. As per my Scenario whenever a text file stored in Application server of the R/3 system. it should be sent as a attchment with a mail.so i set a sender communication channel with file adapter in sender R/3 system . i dont know which business system should i refer for my receiver communication channel.because my receiver end is a mail server. should i create any third party business system for this one?

can anyone suggest me to define a receiver comm channel in a right manner?
