After changing the configuration values to:
conf['activesync']['enabled'] = true;
$conf['activesync']['emailsync'] = true;
$conf['activesync']['version'] = '14.1';
$conf['activesync']['logging']['path'] = '/var/log/horde';
$conf['activesync']['logging']['type'] = 'custom';
$conf['activesync']['ping']['forcedheartbeat'] = 60;
$conf['activesync']['ping']['deviceping'] = false;
$conf['activesync']['ping']['waitinterval'] = 60;

The behaviour has changed. Now I've got pings/updates/polls every 10
seconds. But 10 seconds is not what I've configured.

A "waitinterval" of 60 would be much better. But only 10 seconds seem the
be accepted.. I've configured the version to 14.1 to get the "notes" sync
feature, too.
