SMTP-Gateway 5.0
sender (parameters MaximalIncomingSessionsPerlP and Maxima-
lOutgoingSessionsPerHost)
If the mail traffic at your server exceeds the specified limits, we recom-
mend that you:
• Limit the number of objects simultaneously processed by the anti-virus
kernel (AntiviralSessions parameter) and the number of hops for a
single message (MaximalIncomingMessageSize option). This in-
creases application performance and message processing speed
If your server has a low-speed Internet connection, the following actions
are recommended:
• Decrease the number of objects simultaneously processed by the Re-
ceiver and Sender modules (IncomingSessions and OutgoingSes-
sions options).
• Decrease the maximum number of incoming messages received dur-
ing one session (MaximalIncomingMessagesPerSession option).
6.2. Setting up connection receiving
interfaces
The set of interface and ports, used by the application to receive the
connections, is defined by ListenOn parameter in section [smptgw.network] of
the application configuration file. By default, Kasperksy STMPT-Gateway listens
for connection on port 25 using all available interfaces.
If a particular interface is to be used rather than all available interfaces or if it is
necessary to use a port other than 25, additional settings configuration must be
performed.
Configure the application to wait for connection on port 1025 of inter-
face 192.168.0.1:
In order to do this, modify the value of parameter ListenOn, section
[smtpgw.network] as follows:
ListenOn=192.168.0.1:1025
In order to use several particular interfaces, create several ListenOn parameter
records in the configuration file.
