Specify the path of OpenSSL with --with-openssl. In most Linux systems, it is installed in /usr. If OpenSSL is installed in non-standard places, type ./configure --help for options.

Default installation location is /usr/local. If you want to change that:

The name of the binary will be mailsend. If compiled with OpenSSL, the support for STARTTLS and SMTP over SSL will be available.

Starting from mailsend v1.18, Debian package is no longer supplied. If you want to build the Debian package yourself, after compiling mailsend, type:

To install the package, type:

To uninstall, type:

A compiled binary with SMTP authentication support for MS Windows is already supplied. However, if you need to modify something or want to compile it yourself, you will need freely available Visual Studio from Microsoft. For Visual Studio 2015 community edition, start Developer Command Prompt for VS2015.

OpenSSL is required, if you need to compile with SMTP authentication support. Look at INSTALL.32 that comes with OpenSSL on how to compile and install OpenSSL. mailsend’s Makefile.nmake expects it to be installed at c:\openssl

To compile mailsend, open a command shell and type:

It compiles cleanly with cygwin as well. The name of the binary will be mailsend.exe
