Configures the maximum number of seconds to wait when the Wrapper attempts to send a command to the SMTP server.
Note that several commands are sent to the SMTP server when sending an email, but this timeout controls the maximum amount of time allowed to send each single command.
Additionally, another timeout applies when waiting for a reply from the SMTP server. It is controlled by the wrapper.event.<event_name>.email.receive.timeout property.
Hence, the total time required to send an email may be up to the sum of the timeouts applying for each command being sent.
The default value is 30 seconds, with valid values in the range of 0 to 300.
Values larger or smaller than this range will be silently adjusted.
Globally for all events: wrapper.event.default.email.send.timeout property, or
For a specific event: wrapper.event.<event_name>.email.send.timeout property.
The "<event_name>" component of the property name can be
either the keyword "default",
or one of the Event Types.
By setting the default property,
all Event Types which are not set explicitly will take on that value.
