Exim is now checking data from external sources much more rigerous
and does not longer trust it. For the concept behind this:

http://www.exim.org/exim-html-current/doc/html/spec_html/ch-concept_index.html

Search in that index for the keyword 'de-tainting'.

In your case: "$local_part" is tainted, and has to be changed
so that it can be considered trustworthy.
