What's new in HS SMTP C Source Library 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 re-liability and code robustness in both of SSL and non-SSL related areas of the code

How It Works
To send a text email message to any address on the internet, the user application calls a single function HsSmtpSendMail, specifying mail server name or IP address, sender address, recipient address, message text buffer and length, subject, cc and an event callback function to use for reporting of operation result and server errors. HS SMTP library then resolves the server name, connects to it and transmits the message according to SMTP RFC 821 protocol. HS SMTP Library incorporates the necessary state machine, transparency procedures, and server response processing required to comply to a simple and robust SMTP client implementation. Modular design makes it easy to port HS SMTP protocol module to any environment. HS SMTP internally at a lower layer interfaces to HS Sock library which provides TCP transport services. User application need not worry about Winsock - HS SMTP does all transmission, reception and event handling over socket layer.
