"Expunging a message only decreases the message's refcount. The space is later freed in "purge" step. This is typically done in a nightly cronjob when there's less disk I/O activity. "

What happens if there is filesystem hard quota that is exceeded? Will dovecot allow to delete mails to free space without a need to wait for cronjob to do the purge?

No. Also the purging itself won't work, because it needs to write new data first before it can delete old data. Don't run out of disk space!

Can dovecot treat soft quota like hard quota for user then?

Or better enforce quota based on filesystem quot information. With xfs I can set quota but turn enforcement off. All fs quota counters work but no enforcement is being made by xfs itself.
