iOpus Secure Email Attachments - Encrypted and Self-extracting   
http://www.iOpus.com

Let's face it, in the real world many people simply aren't willing to buy and install a specific encryption package just to be able to read a couple of files you send them. With iOpus Secure Email Attachments (SEA) they don't have to, because you can send them self-decrypting archives that "unpack" themselves. The recipient just double clicks on the file and enters the password at the prompt displayed. The original files are then decrypted, extracted and written to your disk automatically. In just a few moments, you can create an encrypted, compressed (ZIP) attachment with your sensitive documents. Ideal for sending information by email or making secure backups. Thanks to compression, iOpus SEA packages are up to 95 % smaller than the original files, saving time and money for e-mail transmission. The recipient requires no special software, because iOpus SEA packages decode themselves after the password is entered. If desired, your company logo, a custom message, and a link to your home page can be displayed: the perfect combination of branding and security. In addition, your disclaimer may be displayed: your client has to accept it before decrypting the iOpus SEA package.  iOpus SEA uses the Blowfish encryption algorithm with a key length of up to 448 bits. Blowfish encryption is so strong that it has never been cracked yet. In fact, most experts agree that it cannot be cracked with current computer technology and that includes supercomputers! Your time is not worth waiting for your computer to do what you want him to do. iOpus SEA is very fast. Encrypting or decrypting a file hardly takes any longer than copying it. iOpus SEA protects your data not only on its way across the internet, but also on the recipient's PC. Easy to learn - no training required 

wodMailbox

WeOnlyDo! Mailbox is a component that can be easily integrated into your applications to provide full management over mailboxes and message parsing. Using wodMailbox, you can easily access mailbox, count messages, look at messages, count parts, save attachments, look at headers, delete messages etc.. When wodMailBox opens mailbox, it expects to find there either regular mailbox just as is used on UNIX systems (one file with full mail messages one after another) or just one message inside, just as Outlook Express saves .eml files. When you need to parse received messages, it might be hard to check all the possibilities that one simple mail message may contain. We all used to receive simple email messages - few headers and body text. But, sometimes you get attachments, multipart messages, different encodings and stuff like that. It's almost the same for wodMailbox - it's light, quick and fully supports all mail related RFC's. You can look on using wodMailbox for three main purposes: When you want to access mail messages in the mailbox When you want to access and parse one mail message When you want to prepare and create new message Using together with wodPop3Server and wodSmtpServer (or any other UNIX-alike server) you will notice that easiest way to store messages on per-user basis in files. So, one file contain all the messages for one user. If user moves to different computer or account, it's easiest this way to move his email also. Moreover, IMAP and similarly 'larger' protocols keep all the mailboxes this way - all users' messages in one file, on per-user basis. Once you want to access such mailbox, you just pass it's reference to wodMailbox.Filename property, and call Lock method. At this moment, wodMailbox will open the mailbox and count all the messages for you, but trying to use as low amount of memory as possible. This way, it can open and parse large mailboxes (few megabytes is considered to be 'small' at this point) with ease.
