Explanation:
The default SMTP connection time out is 3 minutes. The default value for SMTPTimeoutMultiplier is 1. Increasing SMTPTimeoutMultiplier to 3 will cause connections to remain open for 9 minutes instead of 3 minutes. Setting SMTPTimeoutMultiplier to 100 would keep the connections open for 5 hours!

Default:

When SMTPTimeoutMultiplier is absent, or set to 0 or 1, the multiplier is 'off' and the SMTP time out is 3 minutes.

Recommendation:

A long, long time ago when developing R5, networks were sometime slow. Increasing the time out would sometimes be helpful. However, keeping bogus connections open for an extended period of time is going to take a toll on server performance. Be very careful when increasing this value. The default time out is most likely already too high. Increasing this time out is probably ill advised. If you do increase this value, only increase it as much as necessary and no more. Do not pick some arbitrarily high value.

Restrictions:

This setting was introduced in R5 (Domino 5.0)

Domino Configuration Tuner:

This setting is included in the DCT catalog of best practices.
