def rfc822date(timeinfo=None, local=1):

Format an RFC-2822 compliant date string.

Parameters	timeinfo	(optional) A sequence as returned by `time.localtime()` or `time.gmtime()`. Default is now.
	local	(optional) Indicates if the supplied time is local or universal time, or if no time is given, whether now should be local or universal time. Default is local, as suggested (SHOULD) by rfc-2822.
Returns	A `bytes` representing the time and date in RFC-2822 format.

def idGenerator():

Undocumented

def messageid(uniq=None, N=lambda : next(_gen)):

Return a globally unique random string in RFC 2822 Message-ID format

<datetime.pid.random@host.dom.ain>

Optional uniq string will be added to strengthen uniqueness if given.

def quoteaddr(addr):

Turn an email address, possibly with realname part etc, into a form suitable for and SMTP envelope.

def sendmail(smtphost, from_addr, to_addrs, msg, senderDomainName=None, port=25, reactor=reactor, username=None, password=None, requireAuthentication=False, requireTransportSecurity=False):

Send an email.

This interface is intended to be a replacement for smtplib.SMTP.sendmail and related methods. To maintain backwards compatibility, it will fall back to plain SMTP, if ESMTP support is not available. If ESMTP support is available, it will attempt to provide encryption via STARTTLS and authentication if a secret is provided.

Parameters	smtphost	The host the message should be sent to. (type: `bytes`)
	from_addr	The (envelope) address sending this mail. (type: `bytes`)
	to_addrs	A list of addresses to send this mail to. A string will be treated as a list of one address.
	msg	The message, including headers, either as a file or a string. File-like objects need to support read() and close(). Lines must be delimited by '\n'. If you pass something that doesn't look like a file, we try to convert it to a string (so you should be able to pass an `email.message` directly, but doing the conversion with `email.generator` manually will give you more control over the process).
	senderDomainName	Name by which to identify. If None, try to pick something sane (but this depends on external configuration and may not succeed). (type: `bytes`)
	port	Remote port to which to connect. (type: `int`)
	username	The username to use, if wanting to authenticate. (type: `bytes` or `unicode`)
	password	The secret to use, if wanting to authenticate. If you do not specify this, SMTP authentication will not occur. (type: `bytes` or `unicode`)
	requireTransportSecurity	Whether or not STARTTLS is required. (type: `bool`)
	requireAuthentication	Whether or not authentication is required. (type: `bool`)
	reactor	The `reactor` used to make the TCP connection.
Returns	A cancellable `Deferred`, its callback will be called if a message is sent to ANY address, the errback if no message is sent. When the `cancel` method is called, it will stop retrying and disconnect the connection immediately. The callback will be called with a tuple (numOk, addresses) where numOk is the number of successful recipient addresses and addresses is a list of tuples (address, code, resp) giving the response to the RCPT command for each address. (type: `Deferred`)

def xtext_encode(s, errors=None):

Undocumented

def xtext_decode(s, errors=None):

Decode the xtext-encoded string s.

Parameters	s	String to decode.
	errors	codec error handling scheme.
Returns	The decoded string.

def xtext_codec(name):

Undocumented
