| + | Wrote a handy little program to summarize the exim rejectlog failure from the most recent few such log files: | ||
| + | # Rejectlog_report | ||
| + | 6313 Unrouteable address | ||
| + | 1013 relay not permitted | ||
| + | 8 SPF check failed | ||
| + | 7 SMTP protocol synchronization error (input sent without waiting for greeting) | ||
| + | 7 maximum allowed line length | ||
| + | 3 unqualified address not permitted | ||
| + | 1 SMTP protocol synchronization error (next input sent too soon: pipelining was not advertised) | ||
| + | 1 missing or malformed local part | ||
| + | 1 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. | ||
