Hello, talking to oneself seems to be all the rage on this ML, so I shall join that trend.
As it turns out this was a case of slightly muddled/unclear error messages, the client sees: --- -ERR Plaintext authentication disallowed on non-secure (SSL/TLS) connections. --- But the actual issue was that the newly added "login_source_ips" (the main reason for this upgrade, as we're running out of ports) was not not in the "trusted_networks" of the target mailbox server. So the failure was between proxy and mailbox server, not client and proxy. After adding that network all is working now as expected.
