Receiver email channel - configuration of 'To' email id's

Hi,

In one of my objects, i am using a mail package for the receiver email channel. However, if i use that, i am not able to populate the remaining details (To email id's, Subject etc.,) in the channel directly(i mean in the int directory - mail channel config). This is forcing me to populate the 'To' email id's through mapping. But this is not correct since we need to change the mapping, everytime, we want to add/delete/change the 'To' email id's.

Can you please suggest any resolution ?
