Hi Jeremy, thanks for your explanation!
Im using FreeBSD and consequently an UFS Filesystem (with
DIR_HASH and SoftUpdates enabled). I will delete the emails, but I
posted this question just to make sure that my problem was caused by the
high number of files in the user's Maildir. The next step is to avoid
that an user have so many emails in his Maildir, perhaps enabling quota
for all users...
I frequently face high IO loads in this server, even though its
has one dedicated disk for the qmail queue and logs.
