Overview

Devloper-Smtp-Server is a tiny SMTP server that is designed to allow developers to quickly check the mail sending functions of their application are working.

Features

How to get SMTP name in c#? Sending mails with SMTP (SMTP Error: Could not authenticate). Find Host Name and IP Address of Computers Connected to LAN. Local hosting and windows hosting SMTP email. The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.5.1 Authentication Required. SMTP server written in C#. Doesn't actually deliver any mail, but perfect for testing that your app is correctly sending mail. nikropht/Developer-SMTP-Server. SMTP server written in C#.

The SMTP Server component (ces.smtp.server.dll) provides the ability for programs to implement a SMTP Server and process the incoming email in custom code.

  • Simple GUI
  • Multi-threaded, allows you to plug the server component into your own solution

Use

  1. Start the server with:DeveloperSmtpGui.exe
  2. Point your mail-sending application to localhost, on port 25.
  3. Send your mail, get satisfaction from the fact that it shows in server's window.

That's it.

Slightly more complicated use

You can customise the port and ip address being used by the server. All configurations are contained in the App.config file.

Ip Address Binding

The line below defines the Ip Address being used by Super-Smtp-Sever.

  • Any means any ip address that your computer has.
  • If you want to specify an ip address, put it in standard IP for. (eg. 192.168.1.10)

Port Binding

The line below defines the port that Super-Smtp-Server uses.

Arrays allow to define type of variables that can hold several data items of the same kind. Similarly structure is another user defined data type available in C that allows to combine data items of different kinds.

Structures are used to represent a record. Suppose you want to keep track of your books in a library. You might want to track the following attributes about each book −

  • Title
  • Author
  • Subject
  • Book ID

Defining a Structure

To define a structure, you must use the struct statement. The struct statement defines a new data type, with more than one member. The format of the struct statement is as follows −

The structure tag/recording-software-with-auto-tune.html. is optional and each member definition is a normal variable definition, such as int i; or float f; or any other valid variable definition. At the end of the structure's definition, before the final semicolon, you can specify one or more structure variables but it is optional. Here is the way you would declare the Book structure −

Accessing Structure Members

To access any member of a structure, we use the member access operator (.). The member access operator is coded as a period between the structure variable name and the structure member that we wish to access. You would use the keyword struct to define variables of structure type. The following example shows how to use a structure in a program −

When the above code is compiled and executed, it produces the following result −

Structures as Function Arguments

You can pass a structure as a function argument in the same way as you pass any other variable or pointer.

When the above code is compiled and executed, it produces the following result −

Pointers to Structures

You can define pointers to structures in the same way as you define pointer to any other variable −

Now, you can store the address of a structure variable in the above defined pointer variable. To find the address of a structure variable, place the '&'; operator before the structure's name as follows −

C# Smtp Example

To access the members of a structure using a pointer to that structure, you must use the → operator as follows −

Let us re-write the above example using structure pointer.

When the above code is compiled and executed, it produces the following result −

Bit Fields

Bit Fields allow the packing of data in a structure. This is especially useful when memory or data storage is at a premium. Typical examples include −

How To Create Smtp Server

  • /hot-cues-traktor-pro-2.html. Packing several objects into a machine word. e.g. 1 bit flags can be compacted.

  • Reading external file formats -- non-standard file formats could be read in, e.g., 9-bit integers.

C allows us to do this in a structure definition by putting :bit length after the variable. For example −

Here, the packed_struct contains 6 members: Four 1 bit flags f1.f3, a 4-bit type and a 9-bit my_int.

C'est La Vie

C automatically packs the above bit fields as compactly as possible, provided that the maximum length of the field is less than or equal to the integer word length of the computer. If this is not the case, then some compilers may allow memory overlap for the fields while others would store the next field in the next word.
