nothing else i do after receiving the 220 string seems to have any effect.

stunnel is merely copying terminal input to/from the remote server. Your terminal is probably generating LF-terminated lines of text.

SMTP uses lines of text terminated by CRLF. The remote server is just waiting for input terminated by CRLF.
