[Edit, I've been waiting three hours to use a new email address. I still have the little "creation pending" clock next to the mailbox name ]
Just a few weeks ago, I was able to add a new email user then use that account to send and receive email with a wait of less than 10 minutes. Now, the message near the top of the add-email-user-page states that it will take one to two hours!!
For me, this is a huge disappointment and a major inconvenience. I'll be forced to look at other hosts if this policy is permanent.
