    \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.
