[cobalt-users] Web interface for POP3

["Zarrir Junior" <zarrir@xxxxxxxxxxxx>]

     I have installed rymo, which is a simple but effective web interface
for my Cobalt users to access their POP3 mailboxes, although without
MIME/attachments support. The users have to input the mailserver name, email
address , username and password.
    My question is: Is there a way i can force these users to always access
the web interface for their emails? What i want is a way to block access to
the mailboxes from their particular Outlooks, Eudoras  or Messengers, if
they input the same data they use for the web interface. In fact, i want to
disencourage spammers instead of having to suspend them later.
     Regards,
            Zarrir
