# Introduction

Mailparse is an extension for parsing and working with email messages. It can deal with » RFC 822 and » RFC 2045 (`MIME`) compliant messages.

Mailparse is stream based, which means that it does not keep in-memory copies of the files it processes - so it is very resource efficient when dealing with large messages.

> Note:

> Mailparse requires the mbstring extension, and mbstring must be loaded before mailparse.
