+- 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).
