Overview

E-mail configuration using OMA client provisioning is rejected by the device

Description

We have created an e-mail configuration XML file according to the examples in "Series 60 Developer Platform 2.0: OMA Client Provisioning", but did not include the FROM parameter or the SERVICE parameter in the APPLICATION parts.
When the settings reach the device, it only lists the GPRS access point that we have defined but not the POP mailbox settings.  Are the FROM and SERVICE parameters mandatory?

Solution

As is stated in the document "Series 60 Developer Platform 2.0: OMA Client Provisioning," under E-mail Example:
In general, parm values are not checked, but the FROM field must contain a valid e-mail address or the settings will be discarded. In addition, if PROVIDER-ID is defined, it must have the same value in the SMTP and POP3/IMAP settings. Transport Layer Security (TLS) is used if parm SERVICE is found and it contains the value STARTTLS.
In other words; yes, the FROM parameter MUST be given, but SERVICE is optional.
