I had a problem with spam that left the maillog webmail account with over 250,000 unread mails and as such the webmail wouldn't open for me. I thought that deleting the account would delete all the mail for that account also. Now when I try to add the account back I'm getting the following error: Error: the account "maillog" can't be created because there is already a system account of that name.
I can't see it in the server manager, is there anything I can do to flush this account completely so I can set it back up?
