How to set the number of concurrent connections manually
This article describes how to change the number of outbound connections of the Gateway role.
The corresponding settings are specified in the file “Gateway Role.config” in “C:\ProgramData\Net at Work Mail Gateway\Configuration\” on the respective gateway role. To edit the file, first stop the gateway role.
Below the tag
<netatwork.nospamproxy.proxyconfiguration ... >
find the tag <queueConfiguration> and add the attributes maxConcurrentConnections="xx" and maxConcurrentConnectionsPerDomain="xx" to it. It should look like this:
<queueConfiguration maxConcurrentConnections="100" maxConcurrentConnectionsPerDomain="10" />
This limits the number of concurrent connections to 100, with a maximum of 10 concurrent connections allowed per domain.
