Restriction of mobile users accessing webmail

[mrbose]

Hi,

I am in a need to restrict mobile phone users from accessing the Webmails. Is there any way to filter out mobile phone IPs in Exim?
Is there any way to filter IPs of devices and provide access to such and such devices only.? Anyone who has nailed it, kindly help me.

Thanks

Hey there! I don't believe there is an accurate list of mobile phone IP addresses. If so, that list would likely be so long it would cause other issues.

I also didn't find any Exim filters with my search that would help with this, but we'll see if any other replies come in here that may be useful.
