Mail PassView allows you to view detailed information on each of the email accounts you have configured on your system. Mainly, it's used for the recovery of passwords although undoubtedly, some people will use it to crack passwords. The information it reveals includes details such as account name, name and e-mail server type of application you use, user name and password. You can save all this information in a text file or copy it to the Clipboard.

The program supports the most popular email clients such as Outlook Express, Microsoft Outlook 2000 and 2002, IncrediMail, Eudora and Group Mail Free. It also reveals passwords and info for IncrediMail, Eudora, Netscape 6.x/7.x, Mozilla Thunderbird, Group Mail Free, Yahoo! Mail & Hotmail/MSN Live Mail (If the password is saved in the applications.). It can even work for Gmail if the password is saved by the Gmail Notifier application, Google Desktop, or by Google Talk.

If you've lost your passwords or just want to snoop, it's worth a try but very hit and miss in it's effectiveness.
