What's the rough downtime an email server can handle without losing any emails? The greylist filter relies on most people's emails resending after a few mins if the first is rejected, so guessing a short enough downtime has no impact?
- LinuxBender 5y agoDefaults depend on the application and actual settings depend on the admin/postmaster. So retry queues will typically be somewhere between 3 to 7 days, depending. High volume sending servers may be shorter. It is rare for short outages to cause emails to be lost unless the outage is due to a fire and the server holding your message melted.
