Are mobile device lists up to date?

We started getting complaints from some Verizon and ATT mobile device users that they are having problems connecting to check email. We have the following Exim setting enabled:
Automatically whitelist known mobile device providers [?] Mail providers are stored in /etc/mailproviders/*
The list is a very short listof RIM IPs:
# ls -l /etc/mailproviders/ total 32 drwxr-xr-x 3 root root 4096 Aug 23 2012 ./ drwxr-xr-x. 111 root root 20480 Sep 24 11:54 ../ drwxr-xr-x 2 root root 4096 Aug 23 2012 rim/ # ls -l /etc/mailproviders/rim total 12 drwxr-xr-x 2 root root 4096 Aug 23 2012 ./ drwxr-xr-x 3 root root 4096 Aug 23 2012 ../ -rw-r--r-- 1 root root 204 Sep 24 04:54 ips # ls -l /etc/mailproviders/rim/ips -rw-r--r-- 1 root root 204 Sep 24 04:54 /etc/mailproviders/rim/ips # cat /etc/mailproviders/rim/ips 206.51.26.0/24 193.109.81.0/24 204.187.87.0/24 206.53.144.0/20 216.9.240.0/20 67.223.64.0/19 93.186.16.0/20 68.171.224.0/19 74.82.64.0/19 173.247.32.0/19 178.239.80.0/20 180.149.148.0/22 180.168.204.0/22
Is the list kept up-to-date or is it deprecated?

  Hello :) I suggest searching for these emails in /var/log/exim_mainlog to see the specific reason for the connection failure. EX:
  exigrep user@domain /var/log/exim_mainlog
  Thank you.

  Michael, I appreciate your input, but that doesn't answer the question: Is the list kept up-to-date or is it deprecated?

  I don't believe it's "kept up to date" as in via cPanel updates, if that's what you're asking.

  Connecting to check mail sounds like a different issue, IMHO.

  That's what prompted the question when we got way too many questions about mobile phones from our help desk. We checked to be sure the mobile device box was checked, which it was, which prompted us to check to see what mobile device providers were listed. Turns out only RIM/Blackberry IPs were listed.

  Hello :) It's likely a good idea to manually whitelist IP addresses from specific providers if you want to always allow those providers to send email to your server. The option you are referring to is really only intended to whitelist emails from blackberry devices, and the feature has not been updated in quite some time. Thank you.
