I would think the time to do this would be more a function of how many users are keeping mail in the mail-store than of the amount of spaced used, given that there are a lot of per-user dbs. TL;DR version: A bunch of users without much mail might be slower than a few users with a ton of mail, regardless of how much disk space is consumed. _______________________________________________ Pkg-Cyrus-imapd-Debian-devel mailing list [email protected] http://lists.alioth.debian.org/mailman/listinfo/pkg-cyrus-imapd-debian-devel
