Google said today that it will graually roll out POP3 (Post Office Protocol) support over the coming weeks to users of its Gmail e-mail service. “With POP3 support, users will be able to transfer their server-based Gmail messages to a client-side e-mail application such as Microsoft’s Outlook and have the messages stored on their local hard drive and thus accessible when they are offline. Users with wireless devices that have POP3-compliant e-mail clients will also be able to download their Gmail messages to personal digital assistants or cell phones. Google is also working on adding an antivirus scanning feature to the Web mail service.”
