Decent SMTP client in C++

Question

Hi, I'd like to have a decent SMTP client-side library in C++ with permissive license (LGPL, BSD, MIT-X, ...). It must have at least rfc821 and rfc2487 conformity and preferably rfc3207 conformity.

I have found some that have not met all the requirements:

1. Poco SMTP
2. DataReel SMTP
3. vmime

If you have any, please kindly share. Thank you!

Answer 1

Linux, Windows or both? I know of a great free Windows client, which is part of Ultimate TCP/IP.

Answer 2

How about libsmtp?

Answer 3

I found DataReel to be most suitable. Thanks for all of your comments.
