My question: Did anybody using delayed expunge have any problem with it?
As the people (FastMail) who sponsored the development of this code, we've been using it for over a year now with no problems at all. It's been great. The performance improvement can be quite significant. Trying to empty a large folder with 10,000+ messages previouly could take minutes, now takes seconds. We then schedule the run of the cyr_expire process during our non-peak time.
Also it does allow much better backups. We schedule our incremental backups to run each day with a 2 day expiry time on the actual cyr_expire, which means apart from deleted folders, our backups include ALL messages that have ever passed through a users folders. David mentioned that his original expunge patches actually even allowed for the delete folder case (silently turned into a rename), which I think would be a nice future improvement so that you can guarantee a backup of every message, every day.
