Please read "GENERAL PROCEDURE" above. > OK thanks Wietse. But as I don't want to be bothered with a bespoke bounce template (and the risk that it gets out-dated as/when the default template changes) I seem to be limited to a minimum delay_warning_time of 1h. If I try to specify delay_warning_time of less (for example 15m) I get error/warning messages that AFAIK can only be fully resolved by creating a bespoke bounce template. It is also causes a fatal 'bad time value or unit' error if I specify a non-integer value for delay_warning_time. Has anyone successfully set a delay_warning_time of less than 1 hour (or, better, less than 30 minutes) without creating a bespoke bounce template?
