'\n' is the same as the ascii value. so writing \r\n should work fine.

Maybe your inputcontent is to long for the toSend array.
Anyways you should try to avoid working with char buffers,
use wxString instead.

I've already checked, the inputContent isn't too long for the buffer, because the simple echo server i've implemented to test the SMTP client sends back correctly all the strings, from the beginning to the end.
It's a 50 elements array, while the inputContent is never longer than 40.
However I'll try with wxString as you suggested :)
I'll let you know...

Still not working... I don't think the problem depends by the type of variables, I think instead there's something wrong on the last two chars for the Carriage Return and Line Feed, there's no other explaination!

Problem solved!!! :)
Now the program sends correctly the e-mail :)
The problem was that as second parameter of the "Write" method I didn't have to put "sizeof(toSend)", but the length of the string sent to the server ("toSend.Length()").
It was so simple, how couldn't I think about this before???
As suggested, I've changed the variable type from char array to wxString.
So Here I post the final working code (I have still to work a lot on it, and I must still add the "Subject", "From", and "To" commands, but at least for now the socket is working :) )
