Summary: No LMTP response for invalid recipient

Initial Comment:
I use strict external lookup like

| StorageDriver /usr/lib/dspam/libhash_drv.so
| ExtLookup             on
| ExtLookupMode         strict
| ExtLookupDriver       ldap

The daemon detects when an invalid user is submitted but continues
processing and fails later silently.  The client does not get a
response hence and runs into a timeout.


$ strace dspamc --classify --user nonexist...@foo.bar   -- < /tmp/sp
...
send(3, "Return-Path: <anneemm...@yahoo.f"..., 4939, 0) = 4939
send(3, ".", 1, 0)                      = 1
send(3, "\r\n", 2, 0)                   = 2
select(4, [3], NULL, NULL, {300, 0})    = 0 (Timeout)
send(3, "QUIT", 4, 0)                   = 4


Log show
