Are there any extensions to Postfix that can aggregate multiple outgoing emails into a single email within some time window?
We're developing an application that runs on multiple hosts and emails notifications to us (the developers @gmail.com) whenever something goes wrong, via a postfix server. However, we've run into issues where the application spews hundreds of such errors in rapid succession, leading Gmail to bounce our messages. This is why we're interested first and foremost throttling messages, but ideally also aggregating messages together into a periodic digest that is emitted at most once per minute. Any other (low-effort) solution ideas would be appreciated as well. -- Yang Zhang http://yz.mit.edu/
