Your Internet Consultant - The FAQs of Life Online
If you are looking for FAQ documents, for instance, you can access the mail server at rtfm.mit.edu. A mail server is a program that takes requests for information and mails back to you what you want to know. rtfm.mit.edu is home to thousands of the Internet's frequently asked questions and answers lists, which you can retrieve via e-mail. (Actually, this is nothing new. In previous chapters, I've showed how to get a variety of files from the MIT document server.) For information, send e-mail:

grab a million files using an e-mail server.
Remember that binary files can't be sent through e-mail, so any files you request will be translated to a 7-bit format. You may be able to choose how your desired files will be encoded--with uuencode or BinHex, for example. Read the server's documentation thoroughly, and experiment by retrieving small files before trying to download every program ever written for your computer.
Note: Electronic mail gateways can be fickle, limiting
the size and type of incoming e-mail, so FTP-by-mail servers allow you to set
the maximum size of messages sent to you. They can split huge files into
smaller chunks that your e-mail gateway can better handle. When you receive the
files, you'll need to put the pieces back together, in the right
