The following lib has been changed a few times:
Deprecated sun version

<dependency>
<groupId>com.sun.mail</groupId>
<artifactId>javax.mail</artifactId>
<version>1.6.2</version>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>javax.mail</groupId>
<artifactId>mail</artifactId>
<version>1.5.0-b01</version>
<scope>provided</scope>
</dependency>
The correct lib is:

<dependency>
<groupId>com.sun.mail</groupId>
<artifactId>jakarta.mail</artifactId>
<version>1.6.4</version>
<scope>provided</scope>
</dependency>

Notice though in master we list them all this is to ensure the older libs are not brought over transitively.
