Hi all wonder if you can help me?! we run Linux servers Red Hat 10 i think that receive mail via POP3?!(presume) that then filters down into users MS Outlook, laptop users VPN in and receive emails using 3G cards that works great. Up until now this has worked fine but the mobile users wish to use phones and PDAs. Ideally we would like to run linux server, MS Exchange equiv maybe Open XChange?!, and users with MS Outlook on PCs, Laptops and PDAs(or equiv for PDAs). The PDAs must use a connection faster than GPRS and allow VPN functionality.

can anyone point us in the right direction? we have HP Ipaqs unfortunaetly they dont run on 3G and GPRS is too slow and also has a its VPN solution has a security issue.

any help much appreciated money no object.

Sorry bout the long haul.

Regards,
Ben
