Why using vmime ?

I was searching for a SMTP/POP3/IMAP library. What I found were either very expensive commercial libraries or free libraries

我曾经寻找发送邮件的类库，它们不是商业化的，就是免费版本但无法提供支持的。

without encryption support. Today many SMTP servers demand a TLS or SSL connection. With an email library that does not support encryption you will not be able to send an email to a Gmail SMTP server.

现在许多SMTP服务器要求实现TLS,SSL协议。

Finally I found vmime, which is a multi platform library for SMTP, POP3, IMAP, SendMail and MailDir with very cleanly written code and hosted on Github, mainly written by Vincent Richard, who did a great work.

最后我发现了vmime，它实现了SMTP, POP3, IMAP,等协议，代码很干净，并且被放在Github上面，主要的作者是Vincent Richard，他太棒了。
