Commercial C++ Email library
I am looking for an excellent C++ email library which has support for

 - SMTP
 - IMAP
 - POP
 - all of the above must be able to support SSL/TLS
 - all of the above should support not just one or plain authentication mechanisms
 - COM, ActiveX componente are allowed but no .NET libraries.

Some rather political requirements:

 - It must be a commercial product (common "open source" is not an option)
 - It must be ISV-licensable, meaning you can buy a source code license

So far I discovered:

 - IP Works from NSoftware
 - Dart Power TCP Mail for Active X from Dart

 - I also know Chilkat, but I do not know if it is possible to license the source.

Can someone provide pros/cons for any of these products or does anybody know further products meeting the requirements above? Most similar questions / answers concentrate on free products. Most topics on commercial products are several years old, so I suspect there are many free alternatives, which I can not use unfortunately.
