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.
