Yes! This account has a big quota (about 50MB)... Here is what I did:
1) Deleted all emails from this account; 2) Increased vfs.ufs.dirhash_maxmem to improve performance on big directories (Thanks to Jeremy who mades me read more about DIRHASH)... And now, I will set the users to NOQUOTA (thanks to you, hehe)... > > Another question... Is there a quota on this account?
