At the first time running SendMailAnalyzer, I got an little issue when view report for the past month/year,
root@localhost:~# service sendmailanalyzer stop root@localhost:~# killall -e sendmailanalyzer root@localhost:~# rm /usr/local/sendmailanalyzer/data/LAST_PARSED root@localhost:~# rm /usr/local/sendmailanalyzer/data/* -R root@localhost:~# for log in `ls -tr /var/log/mail*`; do /usr/local/sendmailanalyzer/sendmailanalyzer -bfl $log; done root@localhost:~# service sendmailanalyzer start
2. No cache file found /usr/local/sendmailanalyzer/data/…/cache.pm
No cache file found (/usr/local/sendmailanalyzer/data/example/2018/04/cache.pm) , please run sa_cache as explain in the documentation (See Caching).
root@localhost:~# for month in 01 02 03 04 05 06 07 08 09 10 11 12 ; do /usr/local/sendmailanalyzer/sa_cache -s "example" -d "2018/$month"; done
