What is MIME?
The MIME or the Multipurpose Internet Mail Extension is a form of the non-text email attachments letting the attachments to be sent on the internet. The MIME actually lets your email client or the web browser to send and then receive things like the audio, video, spreadsheets as well as graphic files using the Internet mail.
MIME has been defined in the year 1992 by the IETF or the Internet Engineering Task Force. The distinguishing characteristic of the MIME message is mainly the presence of the headers of the MIME. As much as your mail recipients have email software that is a compliant of MIME and most of the e-mail software is, you could swap down he files that contains the attachments in an automatic way.
You could actually use up a tool in order to compress large files before ending. Most of the email systems would not actually accept messages that would surpass a certain size. It would always be a good idea for you to send the attached photographs into the JPEG or the Joint Photographic Experts Group format than those of the GIF or TIFF ones.
Moreover, some of the email software uses (.mim) or (.mme) files as the wrapper for the mail containing the non-text attachments. Just make it sure that when you are sending MIME attachments or the users of older versions of the AOL software, as earlier versions do not really handle MIME well.
