An MFC class to encapsulate the SMTP protocol
Also included with the SMTP classes in the download is a class called "CPJNMD5Hash" which provides for calculation of MD5 hashes and HMACs using the MS Crypto API as well as a class called "CNTLMClientAuth" which provides a reusable client side implementation for NTLM authentication.
Important!: Please note that I have been informed that CPJNSMTPConnection is being used to develop and send unsolicited bulk mail. This was not the intention of the code and the author explicitly forbids use of the code for any software of this kind.
- Simple and clean C++ interface.
- The interface provided is synchronous which provides an easier programming model than using asynchronous sockets.
- The code does not rely on the MFC socket classes. These classes have a number of shortcomings, one of which causes problems when they are used in NT services.
- The code can be used in a console application without any problems (Again this is not the case for the MFC socket classes).
- A configurable timeout for the connection can be set through the class API.
- The classes are fully Unicode compliant and include Unicode built options in the workspace file.
- As of v1.1, the classes now fully supports file attachments.
- Full support is included for CC (Carbon Copy) & BCC (Blind Carbon Copy).
- Support for regular email address formats and multiple email address parsing.
- Full support for MIME and MHTML (aka HTML Email).
- Full support for MIME Charsets.
- Comprehensive sample program included which exercises most of the classes functionality.
- As of v2.61, the classes now fully support sending email over SSL. This means that for instance you can use the Gmail SMTP server "smtp.gmail.com" on port 465. Also note that all of the other features such as authentication are fully supported over SSL. For example to use Gmail you will require some form of authentication such as AUTH PLAIN because it does not operate as an open relay (which would facilitate spam).
- Supports numerous authentication protocols including "AUTH CRAM-MD5", "AUTH LOGIN", "AUTH PLAIN" and "AUTH NTLM". An "Auto Detection" form of authentication is also supported. In this mode, the authentication protocols supported by the server are detected and the most appropriate protocol is used.
- As of v2.65, the classes include comprehensive support for DSN's (Delivery Status Notifications) as specified in RFC 3461.
