For me (Gmail), the frequency at which messages seem to delete from my BB varies, but it is usually at the same time new email is delivered to my BB. So if I go 8 hours without receiving an email, old emails will not get deleted from my BB during that time.
If email is coming through on a somewhat regular basis, I find the messages I deleted from webmail rarely stay on my BB more than a few hours.
If you find the messages just are not being reconciled, it might be worth your while to either re-send the service books or remove the account from your BB and just re-add it again.
