    \class NmIpsSettingsManagerBase

    \brief The class is a base class for the POP3 and IMAP4 SettingsManager classes. It is used for

    manipulating SMTP specific settings of POP3 and IMAP4 mailboxex. This class also handles the

    reading and writing of extended setting items that are not part of the standard SMTP, POP3 or

    IMAP account settings through NmIpsExtendedSettingsManager.

*/

    Constructor.

    Creates the NmIpsSettingsManagerBase for loading and saving mailbox specific settings.

    Finds and loads the SMTP account and settings linked to the given POP3 or IMAP account.

    \param mailboxId Mailbox identifier.

    \param account CEmailAccounts created by the settings manager factory. Takes ownership after

    successful construction.

    \param accountType AccountType identifier.
