Using postfix 3.3.0 I recently set, in main.cf, 'delay_warning_time = 15m'. Now when an outgoing message is delayed I see these in the log:
... postfix/bounce[12303]: warning: [built-in]: zero result in delay template conversion of parameter "delay_warning_time_hours" ... postfix/bounce[12303]: warning: please reduce time unit "hours" of "delay_warning_time_hours" in delay template ... postfix/bounce[12303]: warning: for instructions see the bounce(5) manual Strangely (to me), these messages appear 20 minutes (not 15 minutes) after the original message was delayed. I am not using any special delay template: # postconf bounce_template_file bounce_template_file = I have looked at man 5 bounce. Does the built-in template use an undocumented parameter 'delay_warning_time_hours'?
