Those release notes seem to include 9.2.1 as well, is that correct? Because I'm running 9.2.1, and when I go to modify a domain, where I should be able to change mailbox quotas, it just says "Mailbox quota not supported by the mail server."
This is patently false, as SmarterMail 5.5 certainly does support mailbox quotas.
On a side note, we've only had Plesk for about six months, so we should still be getting updates, right? Why are my two servers still on 9.2.1, and Plesk reports that no updates are available? Shouldn't it be updating to 9.2.3?
