Ever since Philip Hazel tried to accommodate some broken email producers by
messing with incoming line endings, there have been problems with products
broken in different ways. As I recall, Philip has done various tuneups over
the last many Exim versions.
You didn't say what version of Exim is running in your Debian
installation...there are backports of newish Exim versions available which
would likely fix your problem.
Note that switching from the Exim 3.x series to Exim 4.x involves a
significant reconfiguration of Exim...it's likely best done by running
debconfig and answering the Exim configuration questions as if you were
starting from scratch. This will not be something to tackle the day before
a vacations on your production server.
