About Internet mail scan
PC-cillin can scan data packets as you download mail messages from an Internet (POP3) mail server making sure infected attachments don't invade your computer. Examples of mail clients that use POP3 mail servers include: Microsoft Outlook, Outlook Express, Eudora Pro, and Netscape Messenger.
The email client retrieves messages from the mail server. These messages are analyzed and any viruses are detected. However, Internet mail scan does not scan message attachments that are already in folders on your computer.
Post Office Protocol 3 (POP3) is the most recent standard protocol for receiving email, whereby a server receives mail on your behalf and stores it until you check your mailbox and download the messages. If you are a home user who connects to a mail server hosted by your ISP or a Web-based email service, you are probably using a POP3 server. If your computer is connected to a local area network (LAN), you might be using a POP3 mail server. Check with your network administrator about how mail is handled on your company's network.
