I've attached two traces. One is when sending mail via smtp.sparkpostmail.com and the other trace is when using smtp.googlemail.com.
In both, the handshake starts using TLSv1.2 but looks like it falls back to v1 at some point. It seems googlemail.com is okay with that because they haven't disabled TLSv1 but sparkpostmail.com has fully deprecated TLSv1 so they close the connection. At least, that's how I'm interpreting the logs; I'm not entirely sure where the problem is occurring.
