Hi, I've been using kannel for a long time and am quite comfortable with
it, but I haven't used
blacklisting before now and can't seem to find answers for the following.
I'm using kannel 1.5.0.
There are a LOT of different instances of 'black-list-regex' mentioned in
the
kannel user guide, but I'm having trouble figuring out the
differences/purpose of each one.
I'm trying to block spam messages both TO and FROM customers which
originate from one source number,
but can't quite get it working.
1) Blocking messages TO customers.
If a spammer is sending out a large volume of messages (i.e. one source
number sending out messages to lots of different destination numbers),
is it possible to black-list them in kannel?
I have managed to block messages from being sent to specified *destination*
numbers, with the following config
group = smsbox
black-list-regex = ....
but that doesn't help much here because there are too many destination
numbers.
Is it possible to similarly block certain *source* (sender) numbers? Do you
know what I mean?
i.e. I'm trying to block all messages being sent which have a specific
source/from/sender number.
2) Blocking messages FROM customers.
The other case is to block a large volume of messages coming FROM a
customer handset (e.g. a customer's handset sending constant messages to a
short code.
My understanding is that the following is meant to work:
group = core
black-list-regex = 0401111111
However, this seems to blocks ALL incoming messages! I can't figure out why.
The bearerbox access log shows the following rejection, no matter what the
incoming number is:
REJECTED - black-regex-listed SMS [SMSC:xxxx] [SVC:] [ACT:xxxx] [BINF:]
[FID:] [META:?smpp?] [from:+614xxxxxxxx] [to:xxxxx] [flags:-1:0:-1:0:-1]
[msg:5:xxxx] [udh:0:]
And the kannel log for that SMSC shows the following message, and kannel
returns a non-zero value in the deliver_sm_resp section.
INFO: Number <+614xxxxxxxx> is not in black-list, message discarded
I've also tried variations like the following, with the same effect.
The following kind of regular expressions definitely work for me in 1)
above, but for some reason don't work here:
- black-list-regex = (0|61)401111111
- black-list-regex = ^(0|61)(400111222|401111111)$
Here is my kannel configuration, with the various black-list-regex attempts
