r Yn Xd S)%a An RFC 5321 smtp proxy with optional RFC 1870 and RFC 6531 extensions.
Usage: %(program)s [options] [localhost:localport [remotehost:remoteport]]
Options:
--nosetuid
-n
This program generally tries to setuid `nobody', unless this flag is
set. The setuid call will fail if this program is not run as root (in
which case, use this flag).
--version
-V
Print the version number and exit.
--class classname
-c classname
Use `classname' as the concrete SMTP proxy class. Uses `PureProxy' by
default.
--size limit
-s limit
Restrict the total size of the incoming message to "limit" number of
bytes via the RFC 1870 SIZE extension. Defaults to 33554432 bytes.
--smtputf8
-u
Enable the SMTPUTF8 extension and behave as an RFC 6531 smtp proxy.
--debug
-d
Turn on debugging prints.
--help
-h
Print this message and exit.
Version: %(__version__)s
If localhost is not given then `localhost' is used, and if localport is not
given then 8025 is used. If remotehost is not given then `localhost' is used,
and if remoteport is not given, then 25 is used.

t d S)a8 Override this abstract method to handle messages from the client.
peer is a tuple containing (ipaddr, port) of the client that made the
socket connection to our smtp port.
mailfrom is the raw address the client claims the message is coming
from.
rcpttos is a list of raw addresses the client wishes to deliver the
message to.
data is a string containing the entire full text of the message,
headers (if supplied) and all. It has been `de-transparencied'
according to RFC 821, Section 4.5.2. In other words, a line
containing a `.' followed by other text has had the leading dot
removed.
kwargs is a dictionary containing additional information. It is empty
unless decode_data=False or enable_SMTPUTF8=True was given as init
parameter, in which case ut will contain the following keys:
'mail_options': list of parameters to the mail command. All
elements are uppercase strings. Example:
['BODY=8BITMIME', 'SMTPUTF8'].
'rcpt_options': same, for the rcpt command.
This function should return None for a normal `250 Ok' response;
otherwise, it should return the desired response string in RFC 821
format.
