Blackberry mail issues

Its a common issue in web hosting environment that blackberry device may encounter error connecting to mail server while configuring mail accounts. Please whitelist the following blackberry network ips in the firewall to fix the issue:

If you are using csf firewall adding to csf.allow file will not be enough, as adding to csf.allow can still be blocked by lfd.

If you want to permanently fix this issue we may need to add this to csf.ignore file manually.
