44| Configuring monitor functions Manual
» Port – Specify the TCP port to be used when connecting to the POP3 mail server (POP3
Default port is 110).
» Timeout – Specify the connection timeout in milliseconds. The check will fail if a
connection is not established before the specified timeout elapses.
» Requires an encrypted connection (SSL) – Select this option if you want to encrypted the
transmission (i.e. establish a secure session by electronically authenticating each end of
an encrypted transmission).
» Login to mailbox – Select this option if you want to verify mail box authentication on your
mail server.
» Mail count in folder - Select this option if you want to count the number of emails in a
POP3 mail box. In addition, you must specify the:
Logical comparison operator: State if the count should be „equal to‟, „not equal to‟,
„less than‟, „less than or equal to‟, „greater than‟, „greater than or equal to‟ a
specified value.
The value (i.e., the number of emails) to which the retrieved count will be compared
to.
When the „Login to mailbox‟ option is selected, alternative credentials will be required
so that this check can remotely log on to the mailbox on your POP3 server. The New
Check Wizard automatically prompts you to configure these alternative credentials
(i.e., the user name and password) during the creation of this check. After the check
has been created, you can make changes to alternative credentials from the Check
properties dialog > „Logon Credentials‟ tab.
4.2.6 SMTP Mailserver check
GFI Network Server Monitor can check the availability of SMTP mail servers. The SMTP Mailserver
check initiates a handshake connection to the remote SMTP port and through the replies
received, it can verify if the remote server‟s SMTP protocol is working properly. This check can
also be configured to physically log on to the server (where applicable) and gain access to the
SMTP service. Once logon is authorized, the SMTP check can also send a physical test email to a
target email address. This will verify that the SMTP service is indeed running, accessible and
delivering the required service to end users.
The SMTP check also supports logon to the SMTP server using SSL. Through SSL, you can secure
the transmission session by electronically authenticating each end of an encrypted transmission.
