Category: daemon
Group: v3.9.0
Status: Open
Resolution: None
Priority: 5
Private: No
Submitted By: Enrico Scholz (ensc)
Assigned to: Hugo Monteiro (hmonteiro)
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

[PATCH 1/3] dspamc: accept empty response from server
[PATCH 2/3] Send always a final '.' in DSPAM LMTP mode
[PATCH 3/3] Stop processing of users which could not be resolved by
external lookup

Message:
Indeed. I believe the problem was that when implementing external user
lookup, i only considered mysql and psql for user validation and i
completely forgot the hash driver.
I'll keep you posted.
Best regards,
Hugo Monteiro.
