[horde] ActiveSync email disabled. But horde connects to imap server?

[Erling Preben Hansen]

Hey

I have set up ActiveSync as this:

$conf['activesync']['emailsync'] = false;
$conf['activesync']['version'] = '14.1';
$conf['activesync']['autodiscovery'] = 'full';
$conf['activesync']['hosts']['imap']['host'] = 'eph.dk';
$conf['activesync']['hosts']['imap']['port'] = 993;
$conf['activesync']['hosts']['imap']['ssl'] = true;
$conf['activesync']['hosts']['pop']['host'] = 'eph.dk';
$conf['activesync']['hosts']['pop']['port'] = 995;
$conf['activesync']['hosts']['pop']['ssl'] = true;
$conf['activesync']['hosts']['smtp']['host'] = 'eph.dk';
$conf['activesync']['hosts']['smtp']['port'] = 465;
$conf['activesync']['hosts']['smtp']['popauth'] = false;
$conf['activesync']['hosts']['smtp']['ssl'] = true;
$conf['activesync']['outlookdiscovery'] = true;
$conf['activesync']['logging']['type'] = 'horde';
$conf['activesync']['ping']['heartbeatmin'] = 60;
$conf['activesync']['ping']['heartbeatmax'] = 2700;
$conf['activesync']['ping']['heartbeatdefault'] = 480;
$conf['activesync']['ping']['deviceping'] = true;
$conf['activesync']['ping']['waitinterval'] = 120;
$conf['activesync']['enabled'] = true;

I can see in my logs that Horde is opening and authenticating a connection
to my imap server.
This connection is open for 30 minutes and then closes and immediately
opens again.
Imap is only handling mails

Horde authentication is done to sql server so there is no need to open
Imap.
Horde is handling Calendars Contacts Notes and Tasks.

Is this normal behavior.......
and why is it so.
