/**

 * Integrates with Spring SendGrid by using Spring properties defined with

 * prefix {@code spring.sendgrid} (see {@link SendGridProperties}).

 * 

 * If both Spring property and Ogham property is defined, Ogham property is

 * used.

 * 

 * For example, if the file application.properties contains the following

 * configuration:

 * 

 * <pre>

 * spring.sendgrid.api-key=foo

 * ogham.email.sendgrid.api-key=bar

 * </pre>

 * 

 * The {@link SendGridSender} implementation will use foo to connect to the

 * SendGrid service.

 * 

 * <p>

 * This configurer is also useful to support property naming variants (see

 * <a href=

 * "https://github.com/spring-projects/spring-boot/wiki/relaxed-binding-2.0">Relaxed

 * Binding</a>).
