That Sleep() call shouldn't be necessary - just for debugging use?

See sockreadline() in
http://cvs.synchro.net/cgi-bin/viewcvs.cgi/src/sbbs3/mailsrvr.c?revision=1.621
It's recv()'s one byte at a time a builds up the string until a \n is received.
You could easily adapt that to terminate on \r instead.
I purposely pointed you to an old revision that doesn't support TLS, because
the implementation is more simple.
