python - twisted SMTP server limit incoming email message size -


This is a very basic code that I am using to make SMTP server in twisted: 

  by email. Import headers, twisted.internet, import from imported, twisted.mail import from reactor zope.interface import class ConsoleMessage delivery (object) from device: smtp istmp;% s "% (myHostname, clientIP, Smtp.rfc822date ()) "Received:% s from% s with"% s "% header (headerValue) def validateFrom (auto, hello, original): # All addresses are accepted return original def ValidateTo (self, user): # The message sent to the user only "console @ domain" is accepted. User.dest.local == "console": return lambda: increase console message (smtp.SMTPBadRcpt (user) class ConsoleMessage: tool (smtp.imessage) def __init __ (self): self.lines = [] Def line (self, line): self.lines.append (line) def eomReceived (self): print "New message received:" print "\ n" .join (self.lines) self.lines = any Also defer.Sciceed Returns (None) Def ConnectionList (Self): # There was an error, throwing stored lines self.lines = Any class LocalSMTPFactory (smtp.SMTPFactory): def buildProtocol Automatic, SmtpProtocol = smtp.ESMTP () smtpProtocol.delivery = console message delivery () Returns smtpProtocol reactor.list NCP (2025, local SMTfactor ()) reactor.ron ()   
 I can get emails, but if I want to cancel incoming message size of 1MB or more, how can I do this?   
 
 
 Note that  is ConsoleMessage.lineReceived  with each row of the message called . The size of each line (its length is similar, there is no doubt in it). You can get the size of all the lines, as they get and act on the basis of the result.  
 In addition to this, you can find the  SIZE  ESMTP extension which allows the server to declare the maximum message size that will be accepted. This Code does not check the handle  to replace  from the message rows because there is no guarantee that the customer will respect the declared max, but in the case of a smart, collaborative customer, save some useless data transfers.  
  SIZE  is a simple enough extension that you can possibly twist the ESMTP server by  twisted.mail.smtp.ESMTP  subclass and  Extensions can add by adding  the method to add it.

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise. To clarify - this will not be a method error because it is a linked list. There should not be any way involved. import java.awt. *; Import java.awt.event. *; Import javax.swing. *; Import java.util. *; Import java.util.Scanner; Import java.util.LinkedList; Public class TopTenList JFrame {Private TopTenList tt; See the Private JTextArea list; Private JTextField cmdTextField; Private JTextField resultsTestfield; // This GUI window is the code for the public toptist...

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
