How often does qmail retry to send email?

 

Each message has its own retry schedule. The longer a message remains undeliverable, the less frequently qmail tries to send it. The retry schedule is not configurable. The following table shows the retry schedule for a message that's undeliverable to a remote recipient until it bounces. Local messages use a similar, but more frequent, schedule.
