Monitors included into Mail Servers – Exim4 SMTP Mail Server template
Monitors from this application template check availability, performance and resource consumption of an Exim4 Mail Server (SMTP/SMTPS). Also,one of the monitors can send an optional test message via the monitored SMTP server. Exim is a mail transfer agent (MTA) used on UNIX-like operating systems. Exim is free software distributed under the terms of the GNU General Public License, and it aims to be a general and flexible mailer with extensive facilities for checking incoming e-mail. Exim has been ported to most Unix-like systems, as well as to Microsoft Windows using the Cygwin emulation layer. Exim 4 is currently the default MTA on Debian GNU/Linux systems.

IPHost Network Monitor provides application templates (or just “templates” later in document), to create multiple relevant monitors in only a few clicks. Templates facilitate adding typical monitors sets; this can be particularly useful in case of big networks, when creating same-type monitors for many same-type devices is a common task. Application templates are sets of monitors that can be added, using specific predefined parameters, for a given host at once. The said set, added for given host, is displayed as a separate node in tree view pane, and is named application.
There are predefined templates; user can as well generate templates of their own – either out of existing monitors, or by cloning a predefined template. User-added template definitions are saved in XML files and can thus be conveniently augmented or applied to specific needs.
