Bounce on Postfix Pipe Command Execution Failure

[Reid Sutherland]

Hi,

Why does Postfix bounce on command execution failure, or on command 
timeout?  This isn't a situation for a hard failure, please clarify the 
reasoning.


From postfix-2.11.7/src/global/pipe_command.c:672

        } else if (write_status && write_errno != EPIPE) {
            vstring_prepend(why->reason, "Command failed: ",
                            sizeof("Command failed: ") - 1);
            vstring_sprintf_append(why->reason, ": \"%s\"", args.command);
            return (PIPE_STAT_BOUNCE);
