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