It seems like some of the spammers have changed tactics and are now sending messages with 98 or so bad RCPT addresses, which (happily) Exim detects. But now I’m getting a flood of messages in syslog, such as:

2023-05-28 00:24:39 REJECT [168.121.195.104]: bad recipient count high [9]
2023-05-28 00:24:39 H=([168.121.195.104]) [168.121.195.104] F=<70g3gpds9l3n8@???>
rejected RCPT <comercial@???>: Rejected for too many bad recipients

…many lines deleted…

2023-05-28 00:24:39 REJECT [168.121.195.104]: bad recipient count high [98]
2023-05-28 00:24:39 H=([168.121.195.104]) [168.121.195.104] F=<70g3gpds9l3n8@???> rejected RCPT <admin@???>: Rejected for too many bad recipients

I can easily change the configuration to make this happen silently, but I would like some visibility that this is happening, for example, in my daily logwatch output. Has anyone devised a way to cut down on the number of messages without eliminating them entirely?
