We were previously only re-doing the EHLO in the success case, but there are some receiving implementations that seem to roll the TLS failure error forward, returning an error during MAIL FROM: ``` TLS connection failed: error:1408A0C1:SSL routines:ssl3_get_client_hello:no shared cipher (#4.3.0) ``` we want that error to show up while we're considering the connection, so that we can fail over to the next candidate in our list, rather than having it generate a transient failure for the message and stopping there. refs: https://github.com/KumoCorp/kumomta/issues/67
