I started out close to 20 years ago working at Quiksoft Corporation (http://www.quiksoft.com) as a software developer.   There I worked on the EasyMail product line which included C++ libraries, COM components and eventually .Net libraries to handle SMTP, POP3, IMAP4, Message Parsing, and Mail Storage.  At that point I went on to develop SMTPExpress, which is a windows C++ 32 bit message transfer agent used by high volume senders to get their email out as fast as possible.    This was the first generation MTA server and it did very well.   At that point SMTPExpress Pro was born.  The Pro version had additional features including massive IO improvements and delivery rules to help throttle messages to particular domains. Soon after I started working on the next generation MTA, which would be a complete rewrite using a combination of C++ and .Net.  Using C++ and .Net together allowed us to use the right tool for the right job.  We were able to achieve unmatched performance using C++ with inline assembly when needed while building the GUI and business logic using easily maintainable c# .Net code.
