dovecot - Nov 2019 - Error: Corrupted index cache file and Error: Maildir filename has wrong S value

Good day Guys

I have been met with a very interesting set of error messages.

Here is the snippet(s)
https://pastebin.com/raw/nFf79Ebc

(Sorry for all the redacted REMOVED_*.)

Google is proving to be a bit challenging in helping and explaining.

Could anyone please share how something like this happens, but more 
importantly how to recover from this.
doveadm index -u <username> INBOX do the trick?


I also would like to ask the community, is there any tips or tricks any 
of you guys do to mitigate index / cache corruptions.

Many thanks
Regards
Brent Clark

Good day Guys

Just an update, my colleague and I came across this script.

We made a backup, ran it, but unfortunately the problem still persists.
