libsmtp allows programs to send mail directly through SMTP (no sendmail needed). It is designed to be simple and memory efficient, and has slightly untested support for MIME multipart body parts.
Information regarding Project Releases and Project Resources. Note that the information here is a quote from Freecode.com page, and the downloads themselves may not be hosted on OSDN.
This release fixed a missing end-of-line that was embedded in quotes in mime/comm.c, affecting MIME header generation, and some bit op bugs. configure, make, and install were fixed and should now work better.
This is a total rewrite with a completely new API. Multiple recipients, CC, and BCC addresses are supported. The new API allows the application to send its own headers and SMTP commands. The API may still change slightly, so this is considered developers release.
Better examples have been added (a sample generic mail client) and the documentation has been updated. A nasty bug in Recipient handling and some memory leaks have been fixed.
Support for Base64 and Quoted Printable transfer encodings has been added. A description is now sent with attachments. The documentation and examples have been updated.
