Hi,
I am a Qt/c++ coder. I have over 6 years of experience on Qt framework. I also worked on sending email by using libcurl to send email.
I suggest to use Qt framework design gui and also support run in console mode. If you want to support on multi-platform: MAC, Window, Linux. Please choice Qt framework.
Do you intent to send email with attachment or not?
Do you want to send message in format or just plain text?
Please contact me so we can discuss more about this project!
Thanks,
