In Exim 4 there is no problem. Just use a router like this:

defer:
  driver = redirect
  allow_defer
  condition = ${if and                        \
                   {                          \
                   {def:h_some-header:}       \
                   {< {$message_age}{1200}}   \
                   }                          \
              {yes}{no}}
  data = :defer:

That will defer messages that contain the header for 20 minutes.
