Yes and no.
There are two kinds of bounces: Those generated by your mail server internally
and those sent by other mail servers. The first kind can be identified through
them having $caller_uid and $originator_uid equal to that of the Exim user,
and $received_protocol equal to "local". They have a list of failed
recipients in the X-Failed-Recipients header field, which can be processes.
The second kind is trickier since far from all MTAs send easily
machine-readable delivery status notifications. Furthermore, you can often
get bounces for messages neither your server nor any of your users sent, as
well as completely forged bounces, but that might not be a problem.
Mailman, the mailing list manager (
http://www.list.org), has code to parse
many different bounce messages. You could look at that.
