+Wrote a handy little program to summarize the exim rejectlog failure from the most recent few such log files:
+# Rejectlog_report
+Unrouteable address
+relay not permitted
+SPF check failed
+SMTP protocol synchronization error (input sent without waiting for greeting)
+maximum allowed line length
+unqualified address not permitted
+SMTP protocol synchronization error (next input sent too soon: pipelining was not advertised)
+missing or malformed local part
+syntactically invalid
+#
+Look at least the top couple items would be good candidates for adding configurations for fail2ban.
+Some others beyond that may also be worth doing - but not as high a priority.
