4.2.5 POP3 Mailserver check
GFI Network Server Monitor can check the availability of POP3 mail servers. The POP3 Mailserver
check initiates a handshake connection to the remote POP3 port and through the replies
received, it can verify if the remote server‟s POP3 protocol is working properly. This check can
also be configured to physically log on to a specific mailbox and check for the number of emails
present in a folder within the accessed mailbox. This will verify that the POP3 service is indeed
running, accessible and delivering the required service to end users. The POP3 check also
supports logon to the POP3 mailbox using SSL. Through SSL, you can secure the transmission
session by electronically authenticating each end of an encrypted transmission.
