It's 2012, nobody wants to delete an email from the server. When Google Apps Standard launched (50 accounts, 1 GB per account, for free) business were consuming email using Outlook + POP3, deleting the mail from the server. Then you could offer 'ilimited' Cpanel based emnail accounts in less than 1 GB. Business and people have different standards now and consuming email using IMAP, letting the mail in the server, using more storage (7 GB / account) without paying anything. We can't back to the 1GB 'ilimted' accounts scenario. Google has influenced our behavior, has give us the 'first dose', now they come for the money.
