Most of the Blackberries sold on the market come with the Blackberry Internet Service (BIS). What’s so special about it? Well, Blackberry devices, unlike other phones, are integrated with its Push Mail technology through BIS. New emails, contact numbers and calendars are pushed to your mobile phone automatically, as soon as it arrives into your mailbox. Through BIS, your emails will also be scanned from viruses.
“The BlackBerry Internet Service, or BIS, allows BlackBerry users to access the Internet and POP3/IMAP/Outlook Web Access email accounts without connecting through a BlackBerry Enterprise Server (BES). The service is usually provisioned through your mobile phone service provider, though Research In Motion (RIM) (BlackBerry’s developer) actually runs the service. This service uses RIM’s proprietary push technology (in contrast with SyncML-based push technologies such as Funambol) to the BlackBerry devices over cellular carriers; BIS retrieves email from mail servers via POP3 or IMAP is done via polling.”
When you’re asked, “What is your Mail Server?” enter imap.emailsrvr.com, running on port 143. Your outgoing mail server is smtp.emailsrvr.com, running on port 587. The username is your full email address.
For those Blackberry owners without a BIS plan, you can download a third party email client called Tiggitmail. This software is not free.
