- update to exim 4.93
* SUPPORT_DMARC replaces EXPERIMENTAL_DMARC
* DISABLE_TLS replaces SUPPORT_TLS
* Bump the version for the local_scan API.
* smtp transport option hosts_try_fastopen defaults to "*".
* DNSSec is requested (not required) for all queries. (This seemes to
ask for trouble if your resolver is a systemd-resolved.)
* Generic router option retry_use_local_part defaults to "true" under specific
pre-conditions.
* Introduce a tainting mechanism for values read from untrusted sources.
* Use longer file names for temporary spool files (this avoids
name conflicts with spool on a shared file system).
* Use dsn_from main config option (was ignored previously).
