how to use ssl with smtp in c++

Question

Hello all im looking for code example or tutorial on what i need to do to code sending email via email client ( that i already have ) that will support ssl authentication i guess using open ssl

Answer 1

Boost.Asio and the Sockets Library both have SSL support. The latter has SMTP server class but unfortunately no client. I found an example client but it uses the simple C socket.h.

Update: Here are some real working examples. They all support SSL or TLS.

• Msmtp: An SMTP client and SMTP plugin for mail user agents such as Mutt
• sSMTP: Extremely simple MTA to get mail off the system to a Mailhub
• libESMTP: lib that implements the client side of the SMTP protocol
