MailWrench CSharp Command Line Mailer for Windows is now Free Software

Version 2.00 of MailWrench, my newest command-line mailer for Windows, is now free software.  You may download the C# source code, executable file, build script, and the v 1.01 documentation at:

Any further changes to MailWrench will be captured in the following repository:

There’s a new feature in version 2.00 that has a clumsy method of inlining images to HTML emails.  It’s not documented in the supplied HTML file. Here’s a brief description:

To include an inlined image in your email, refer to the image by the following  IMG tag in your HTML:

<img src="${img1}" alt="" />

Then, add the following to your MailWrench command-line:

-img 1 whatever.png

Right now, it’s probably best to keep the images in the same directory as the HTML source file.  I had intended to build something to parse an HTML file for image tags but I just hadn’t gotten around to it.

The included batch file build.bat can be used to compile MailWrench.  I didn’t use Visual Studio nor any other IDE.  I don’t believe that you need a full .NET development kit in order to compile MailWrench.  The standard compiler that accompanies the .NET distributions works nicely.

As the code is barely commented, please feel free to ask questions about sections of it.  ( Please ask them in the comments sections on this post.) Note that I ported MailWrench from a non-OOP codebase, so for expediency’s sake, I opted to code my C# in a non-OOP procedural style.

I have removed the code that performed the nagware protection-scheme warning in the trial version.  I’ll post that code here later and will walk through the genesis of the approach in that post.

    whatever.png is good, but whatever.pdf – not good. How?

    < PDF isn’t an image format that embeds using the IMG tag.
    Yes, but How to send a PDF to gmail?
