There are many reasons:

- Exchange can be hard (if not impossible) to completely secure
against hacking/DOS

- Exchange does not offer the level of access control, filtering, etc.
that Exim does, leading to more junk mail being accepted

- Exchange is not entirely RFC-compliant and occasionally has trouble
accepting legitimate mail from senders that expect full compliance
