Steps to configure Blackberry:

1)   Sign up with Blackberry.net for an email address, i.e., username@blackberry.net

                  2)   Configure SmarterMail account to auto forward email to username@blackberry.net

                  3)   Configure Blackberry to check Blackberry.net email

                  4)   Set the Reply-To setting to your SmarterMail email address

This configures your Blackberry to receive email to the handheld through your Blackberry account. And also configures your handheld to set all outbound email’s replies to be sent to your SmarterMail mailbox
