Modifying SMTP Connection Timeout Values

From MsgServerDocWiki

How do you modify timeout values for SMTP connections?

An option file can be used to control various characteristics of TCP/IP channels. Most of the options described actually relate to the SMTP protocol itself, rather than to the TCP/IP transport. As such, other MTA channels that use the SMTP protocol over other transports may have similar options.

Such an option file must be stored in the MTA configuration directory (msg_svr_base/config) and named x_option, where x is the name of the channel. Note that while master channel programs (the outgoing/destination channel) read the global option file (msg_svr_base/config/option.dat) each time they run, the slave channel program reads the option file only when it is first started, and will not see changes until restarted.

For incoming messages, the TCP/IP channel options (in the SMTP channel options file, for example msg_svr_base/config/tcp_local_option) are options only for the incoming channel (slave channel program). These options are not to be used with other channels that might supposedly handle the incoming messages, for example, channels with the *switchannel keyword enabled.
