Este articulo es una mejora al código que escribí anteriormente. Jugando un poco con Gmail me di cuenta que los correos aún pueden ser recuperados usando POP3, pese a que fueron borrados con IMAP. Realmente bizarro. Así que modifiqué el programa para que manejara un poco mejor el caso de POP3 o IMAP según las propiedades.
Aquí está el código:

Este fin de semana me decidí a poner un poco de orden en mis cuentas de correo; Una de las cosas que me obligó a ello es que mi cuenta paga de Yahoo expiró y aún ando debatiendo si debo pagar $20 por una cuenta de correo que no ofrece nada por encima de Gmail. Al momento de revizar mi cuenta de Gmail me encuentro con que estoy usando por encima de 1 GB en correo con más de 40000 correos.
Si, es increíble la cantidad de basura que se acumula en dos años
Definitivamente no estaba dispuesto a perder mi tiempo borrando tal cantidad de correos a mano, en vez de eso me decicí a automatizar la tarea usando Java y el hecho de que Gmail soporta POP / IMAP (Javamail cuenta con accesso a IMAP comp arte de su API). Una vez leido un poco abrí mi Eclipse y el resultado es el código que viene a continuación:

Correr el código es trivial, asegurese de tener el JAR de Javamail en el $CLASSPATH y haga algo como esto:
java com.kodegeek.blog.mail.ImapBulkEraser -Dmail.user=name.lastname@gmail.com -Dmail.password=XXXX -Dmail.store.host=imap.gmail.com -Dmail.store.protocol=imap -Dmail.store.folder=INBOX -Dmail.imap.port=993 -Dmail.imap.socketFactory.port=993 -Dmail.imap.socketFactory.class=javax.net.ssl.SSLSocketFactory
El programa no es perfecto, ya que de vez en cuando me conseguí con la siguiente error:
NFO: Set delete flag for mail subject: 'Deploying webapps in embedded environment', folder: 'tomcat-user'
