SMTP Listener Services
Timeout limit
The Timeout limit specifies the time the listener waits for the sender.
Listener IP
Either the IP address or resolvable host name of the SMTP server, the SMTP probe is to be run against. This system has been called "remote host" in the description above. Please note that specifying a host name can cause the SMTP probe to fail if DNS name resolution fails (for example due to a failing DNS server). To avoid this, specify an IP address.
