Postfix code works as follows:
for each query pattern # user@domain, @domain, localpart, ...
for each map in mumble_maps
search the map for the query pattern
I left out the code that takes a search result and does something
depending on the query pattern that was matched (user@domain,
@domain, localpart, ...).
The reason for this arrangement of the two loops is that the query
patterns were generated by hand-crafted code, one iteration at a
time. We could change that with a data-driven approach, but it would
be incompatible with existing behavior.
