Hi all! I’ve been looking for a selfhosted system that can monitor one or more email accounts and check if a certain email with a particular subject arrives every day (or every x hours) and alert me if it doesn’t (or if the subject is different). I need this to check if backups from different PC have run or not. The best thing would be to integrate it with Uptime Kuma. Any idea? Thanks!
I would put a simple “grep <whafever> mail.log || curl ntfy.sh” or something like that. Ntfy can send you alert on the phone if some check failed or passed. For pass just use && :) Simple and it works.
Depending on how much infra you want to put up, there’s also mailinabox that can do all (email aliases, etc.)
