New page

'''Mbox''' is a generic term for a family of related file formats used for holding collections of email messages. All messages in an mbox mailbox are concatenated and stored as plain text in a single file. Each message starts with the four characters "From" followed by a space (the so named "From_ line") and the sender's email address. RFC 4155 defines that a UTC timestamp follows after another separating space character.

		+	<pre>
		+	import mailbox
		+	import email.utils
		+
		+	from_addr = email.utils.formataddr(('Author', 'author@example.com'))
		+	to_addr = email.utils.formataddr(('Recipient', 'recipient@example.com'))

		+	msg['To'] = to_addr
		+	msg['Subject'] = 'Sample message 1'
		+	body = "This is the body.\n"
