Is it safe to wipe: /var/lib/cyrus/lock/

[Jan Vales]

Hello,

I just stumbled into this directory: /var/lib/cyrus/lock/

It seems to contain many dead things, like .lock-files that - based on
their names - must be older than 2+ years, including .../user/$NAME
where $NAME does not have a mailbox/account anymore.

Is it safe to shut down cyrus and do a
find /var/lib/cyrus/lock/ -mindepth 2 -delete

Its currently cyrus 3.0.13 on debian 10.

br,
Jan
