I'm trying to set up an email account on a Blackberry. My email server's firewall is blocking it because in the past users have tried to set up email accounts with the wrong password, and my server has detected what it thought was a hack attempt and blacklisted that IP address (range?).
At the moment the only way I can set up an email account on my Blackberry is to disable the firewall completely. I've already whitelisted all the IP ranges in this document, and once the email account is set up then I can send & receive email with the firewall up, but I suspect that there is another IP address (range?) that RIM use to set up the account initially which isn't in this list.
Any help gratefully received!
