POP Connection
•
Without virus scanning
To retrieve e-mail, the e-mail client connects to the mail server directly by using the POP protocol.
•
With virus scanning
When virus scanning is used, Internet Gatekeeper stands between the client and mail server and
operates as the POP server for the e-mail client. The client connects to the mail server through
Internet Gatekeeper. The client retrieves e-mail that has been scanned for viruses. Although
Internet Gatekeeper usually connects to the designated parent server, you can specify that the
connection is created to any POP server. To do this, specify the POP user name in the format
"<POP server user name>@<POP server name>".
