use wireless phone to access email

[lan123]

I need some help with how to setup the secure protections for pop3 and smtp server. Our exchange server is behind a firewall now. For people who need to access email remotely they have to use our VPN client. Now we want to give people the ability to access their email through cell phone. So we need to open the pop3 and smtp to outside access.

Thank you in advance for your help.

Ok, but what is the question?

Thank you for the reply.

Hope this is clear enough.

Thank you.

You say they have to use your VPN client? Will your VPN client really work on a cell phone (I really doubt it)? If these cell phones really use POP3 just open that port on your firewall (110). There is no need to a VPN client if you are using POP3. Otherwise checkout Blackberry and the cellular devices that work it.

Thank you all for the reply. I really appreciate your help.

I think that I did not make it clear in my last post.

Our VPN client can not be insatlled on any kind cell phone that's for sure. What I am really worry is the security issues here. Is that safe if I open pop3 and smtp ports to outside access without any protection (except firewall)? Should I use something like SSL?

Excuse my poor English please.

Thank you.
