Hello, I have an old Fedora machine running sendmail 8.14.1 as a relay of spam reports from a large ISP to our system.
It generally works fine but apparently the follow has happened in the last few days: 1. For one reason or another, it started falling behind on the backlog. 2. By the default configuration, it started to generate the "Can't deliver in 4 hours" warning message to be sent back to the submitters of spam reports. 3. These messages filled up its queue and caused it to fall even further behind. 4. Chaos ensues - incoming connections dropped because of high load average, queue runs never manage to cleanup queues, more messages arrive to the incoming queue, more warnings and bounces are put into the outgoing queue etc. My conclusion is that these spam report delayed warnings and bounce messages are pretty useless - I'd rather drop the warnings, bounce reports and even drop the old spam reports instead of trying to treat them as so important that I just MUST deliver them. I found Timeout.queuewarn but that would only allow me to prolong the time before the warning message is generated or the message is bounced back. I'd like to just drop the message. I'd also like to have these rules only for spam reports, not the administrative e-mails generated by the system. I suspect this might be achievable by dedicating a separate queue for the spam submissions, right? Can someone point me on how to achieve that? The closest I found were scripts to periodically grep and delete specific messages (which is basically what I did ad-hoc today to cleanup the queue).
