The "invalid parameter supplied" is a libsasl error message.
According to posttls-finger (below my signature), they support two
SASL authentication methods: LOGIN and XOAUTH2.
Let's get rid of XOAUTH2:
# postconf -e "smtp_sasl_mechanism_filter = login"
# postfix reload
and see if that makes a difference.
