Use a filter - see the filter.txt file that came with exim, also at
http://www.exim.org/exim-html-current/doc/html/spec_html/filter.html

For a single (unix) user this is usually .forward in home directory.
but it is also possible to enable a "system filter" which all mail
passes through. User filters can be in the internet standard "sieve"
format or the exim filter language; system filters must be in the
exim language.

Here is a possible, untested, filter file for a single user.

------- 8< ------------ 8< ------------ 8< ------------ 8< -----
#exim filter

if $header_msgid_mkt_domain: is not ""
then
     seen save $home/specificfolder
endif


------- 8< ------------ 8< ------------ 8< ------------ 8< -----
