UPDATE 2008.07.16 17:30 Pacific Time
Email services has been restored to the particular accounts.
I was first notified in the morning about the problems with Goggle Mail. Apparently some Google Apps accounts are unable to access their email. The accounts can still access all Google Apps with the exception for email.
In addition to that, the accounts are unable to access mail through Gmail POP and IMAP. The particular accounts cannot access Gmail SMTP server either. Meanwhile other accounts can access Gmail without any problems.
As usual, it is almost impossible to contact Google. All I can find is some web-forms to contact Google Technical Support team.
