[horde] Import of contacts with multiple email addresses

[Benedikt Bäumle]

Hi Horde-Team,

we will soon have to import a lot of contact data from exchange (vcard 
format) to horde and couldn't figure out to import contacts with 
multiple email addresses.

We managed to add custom address fields to our horde installation using 
the following tutorial:

https://monotok.org/add-custom-fields-horde-5-turba/

So we now have three fields for email ( 'Email', 'Home Email', 'Work 
Email' ). But we have no idea how to configure the import to use all of 
the three fields. Currently just the 'EMAIL'-line in our vcard contacts 
are imported and the other email addresses are lost. Is it somehow possible?

An example vcard contact could look like this:

-------------------------------------- VCARD 
--------------------------------------------------

BEGIN:VCARD
FN:Test\, Mister
N:Test;Mister;;;
EMAIL:test at test.com
HOMEEMAIL:test.test at test.de
WORKEMAIL:test at test.de
