Abstract. In this article, the support for MSISDN is described in detail. It allows sending emails to and receiving email from phone numbers.
Enabling MSISDN Support
MSISDN support is disabled by default. In order to enable this feature, you must define the capability msisdn. This is done by simply adding the word "msisdn" to the property "permissions" in /opt/openexchange/etc/permission.properties:
Specifies the used contact columns which can be selected as mail sender or recipient
If the setting is not defined these two columns are used: cellular_telephone1 (551) and cellular_telephone2 (552)
Changing setting to cellular_telephone1 (551), cellular_telephone2 (552) and telephone_other (553)
