In DSpace there is only one feedback recipient. According to our experience, the feedback recipient often redirects e-mails of other persons, depending on the type of feedback.
We developed the following feature: community-based feedback recipients, which are defined by inserting lines like this in the dspace.cfg file:
feedback.recipient.123456789/2 = email1.something.com
where 123456789/2 is the handle of the community.
This means that when the user clicks "send feecback" in the community 123456789/2 (or collections, items or bitstreams under this community), the feedback will be sent to email1.something.com.
If there is no corresponding line let's say for a community with the handle 123456789/15, the feedback will be sent to the original feedback.recipient email.
There are two patches:
patch_communityfeedback.txt, which includes small changes for SendFeedbackAction.java and
patch_conf_file.txt, which include example lines in dspace.cfg
