dovecot - Jun 2021 - Pigeonhole sieve_user_log

https://doc.dovecot.org/configuration_manual/sieve/configuration/

Pigeonhole creates logs separate from main dovecot logs. I see 
sieve_user_log allows you to change log location and it says if you 
don't set it logs are still made by default.

I can not find anything about log rotation of these pigeonhole logs or 
if there is a way to disable this logging. Do i need to worry about this 
log growing out of control? Is there a way to disable it? Does it 
prune/purge itself? Any practical reason to keep these logs?

User log can currently not be disabled.

No, it is rotated when the log exceeds 10k. At most two log files ever 
exist in parallel. The rotated log gets a .0 suffix. There is no .1.

No.

It only rotates. Logs are otherwise kept indefinitely.

Most user-caused problems are not logged anywhere else.
