Borrando correos masivamente usando Javamail
Martes, 30 de diciembre de 2008
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:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 | package com.kodegeek.blog.mail; import java.util.Properties; import java.util.logging.Level; import java.util.logging.Logger; import javax.mail.Session; import javax.mail.Flags.Flag; import javax.mail.internet.MimeMessage; import javax.mail.Message; import javax.mail.Folder; import javax.mail.MessagingException; import javax.mail.Store; import com.sun.mail.imap.IMAPFolder; import java.io.FileInputStream; /** * I wrote this program to erase ALL the email on my GMAIL account.

Nota de los cambios:
- El método expunge sólo es válido para IMAP. Verificamos eso.
- Agregué nuevas propiedades de uso en el Javadoc.
