This is normal.  If you delve into the C code, you'll see that it
calls MXRelayOK (mimedefang.c, line 561) which sends a message to the
multiplexor, which forwards it to a slave... eventually, the answer
comes back to mimedefang.c.

You should not notice much (if any) of a performance impact.  If you
do, let me know, and I'll add a switch to mimedefang.c which makes
these checks optional.
