Sending email via SMTP using HS SMTP C Source Library.

HS SMTP C Source Library is a software library in C (supplied with full source code) which implements the client side of Simple Mail Transfer Protocol (SMTP) over TCP socket layer according to RFC 821. Support for transfer of basic message headers and text is provided. HS SMTP C Source Library supports ESMTP extensions for LOGIN authentication using Base64 encoding and message sending to multiple recipients from an address list.

Updates in V2.0.5

• Two separate code bases one for Windows and one for Linux have been integrated into a single code base that compiles both on Windows and on Linux
• Fixed an issue with sending file attachments over SSL/TLS. The issue appeared when the SSL engine processing stopped in HsSock library, so no new packets were being sent out. This specific issue has been fixed and HsSock Library has been reworked to improve reliability and code robustness in both of SSL and non-SSL related areas of the code
