What single_fields / resolve_single_fields allows you is to build a
structure with a O(1) access, when you want to access quickly a
given data.

Instead of running through all the list of fields to match the
wanted field.

It is not advised to use the single_fields field in mailmessage
structure but you may use mailimf_single_fields_init() to initialize
a mailimf_single_fields structure.

void mailimf_single_fields_init(struct mailimf_single_fields * 
single_fields, struct mailimf_fields * fields);

example :

void foo(struct mailimf_fields * fields)
{
    struct mailimf_single_fields single_fields;

    mailimf_single_fields_init(&single_fields, fields);
    /* read single_fields structure and display information
       or access information */
}
