/**
* Mail accounts supports 3 types of accounts:
*
* a) personal mail accounts either created by admin or user themselfs
* b) accounts for multiple users or groups created by admin
* c) configuration to administrate a mail-server
*
* To store the accounts 4 tables are used
* - egw_ea_accounts all data except credentials and identities (incl. signature)
* - egw_ea_valid for which users an account is valid 1:N relation to accounts table
* - egw_ea_credentials username/password for various accounts and types (imap, smtp, admin)
* - egw_ea_identities identities of given account and user incl. standard identity of account
* - egw_ea_notifications folders a user wants to be notified about new mails
*
* Most methods return iterators: use iterator_to_array() to cast them to an array eg. for eTemplate use.
