Empty variable is the same as undefined:
set acl_m_temp = ${if match{$h_Subject:}{<regex>}{$1}}
condition = ${if def:acl_m_temp}
...
Note, use acl_m_... for that, one connection can transfer
multiple unrelated messages, once acl_c_... will be set,
it can remain in that state for other messages in the
same connection (while not in this case, but anyway).
The acl_m_... will be cleared for every message for you
by exim itself.
