It is perhaps OK to enable delay notifications to the sender, but I would raise the warning time to at least 2 hours. A 30 minute warning is too early, some remote sites may be greylisting for approximately that long, or may not resolve problems quite that quickly. I don't recommend per event postmaster notices, they can compound queue congestion. It is far better to get aggregate data from log parsing. I usually set: # No email notices notify_classes = -- Viktor.
