In webhosting customers usually see their physical disk usage used (quota on filesystem), and it causes a lot of confusion when numbers don't match with doveadm quota at all.
What's your opinion on these: 1) Should indexes (including FTS indexes stored in Maildir) be counted in the mail quota? 2) Shouldn't doveadm quota have a flag for real disk usage, so that if emails are compressed, their real size would be quoted? 3) Shouldn't dovecot rely on st_blocks instead of fstat's st_size? (a benefit for this: in this case converted maildir files without S=... would still be counted into the space used) A short yes/no to 1, 2, 3 would be appreciated.
