Hello, all

We use uucp ( still !!!) for relaying mails for our clients.

I want to implement a uucp ratelimit, so that I can limit how many
mails a particular node can send in an hour.

Is there any implementation already , or will I have to hack the code
myself.

Thanks
Ram

Nice to hear about another user.

Perhaps the quota module of policyd might be useful.

How do I get the uucp node name passed to postfix when the mail is
sent ?

I have many  client servers sending mails to us for relay. When any
one client is compromised then the servers sends abnornmal number of
mails  , this is what I plan to monitor for.

Hello, this is just a shot in the dark since I've only ever played with UUCP
for a project I'm working on.

Are all the mails sent in a single batch file that is processed by rmail
or in multiple files processed by rmail?

If there are huge batch files being sent Taylor uucp seems to have a way to
limit the max size of a file sent to any given system.

I'm sure the problem isn't that simple though. If I were attacking the
problem I would likely write a perl script that runs on the client's system
that examines the UUCP spools for a large amount of queued mail requests
and then can modify the UUCP config to not send (or do whatever you desire)
and send you a mail notifying you of the problem over the UUCP link.

You could likely invoke this perl script in cron just like you do uucico but
either leave execution of uucico to the perl script itself or have the
regular execution of uucico handled by a shell script that first calls
your custom perl script (or whatever language you decide to use)

I'm also assuming that your clients have a UNIX/Linux machine that queues
up mail and sends it via UUCP I hope this helps since like I said before
I've done very little with UUCP other than read a few books and a bit of
tinkering around in my spare time.

I do know though that you can accomplish just about anything you want with
creative scripting under any unix like system.

If the clients are all running postfix at their sites as the SMTP/UUCP
interface you may be able to add a custom header there.

Or it may be enough just to look at the received headers when the mail
is processed on your UUCP hub.

Then you count those headers on your UUCP hub and when a node exceeds
their quota you disable their dial in privileges on the hub.

No  I cannot control the sending servers MTA.
Also I have no reason to trust the sending servers headers

Is there a way I can add the header after the mail has been recd. I am
ready to patch my uucico/rmail for this if required.

Thanks

I know on my OpenBSD/Taylor's UUCP setup, uuxqt sets the environment
variable UU_MACHINE with the remote node name. OpenBSD's rmail pass it
to sendmail so it can use it in the Received header.

But I can't find a description of your setup. (Which unix-like?
Commercial UUCP or Taylor's UUCP? Which MTA you currently use? Is your
rmail from your OS or directly taken from your MTA sources?)

Like the rmail from Postfix is just a shell script. It be easy to call
"formail" from procmail to add any header.

That OpenBSD's rmail trick is only found on OpenBSD and depends on the
sendmail's -p switch which is ignored by Postifx's sendmail
compatibility interface.

I have looked at that policyd thingie and I haven't figured how to use
it for your requirement.

You could use the perl File::Tail module and count the arriving X files,
or the rmail invocations, (in real time) as seen in your hub's uucp/Log.

Feed that information to your statistics tracker...

I use Centos Linux and postfix.

Probably I could use the env variable in rmail

Let me check that
