There have been problems with one of the mail storage servers over the weekend- which may explain why mail from webmail disappeared-
i am not sure whether it has happened this time, but sometimes if a storage server goes down then a backup server is put in place- meaning anything stored on the main server will not appear until this comes back up again. PM me the username for the email account and i'll have a look on monday.
As for the Medic comment- if you want to name and shame then PM the name to me instead
