It's indeed coupled to log rotation currently, but you can change that
by redefining the rotation interval for the alarm summaries. Try this
in local.bro:

    event bro_init()
        local f = Log::get_filter(Notice::ALARM_LOG, "alarm-mail");
        f$interv = 1day;
        Log::add_filter(Notice::ALARM_LOG, f);

Ah, that's outdated, the default log rotation used to be once a day,
but is now once an hour.

We should add a second option here that defines the rotation interval
for the alarm summaries separately.
