opportunistic_tls_reconnect_on_failed_handshake

Since: Version 2025.01.23-7273d2bc

The functionality described in this section requires version 2025.01.23-7273d2bc of KumoMTA, or a more recent version.

When set to true (the default is false), 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.
