opportunistic_tls_reconnect_on_failed_handshake

Since: Dev Builds Only

The functionality described in this section requires a dev build of KumoMTA. You can obtain a dev build by following the instructions in the Installation section.

When set to true, if enable_tls is set to Opportunistic or OpportunisticInsecure, and the TLS handshake, or the subsequent EHLO after the TLS handshake, fails, instead of moving on to the next address in the connection plan, we will establish a new connection to the same address, but with enable_tls set to Disabled.
