Connecting to Exchange Server - Wiping

No I dont think so but chack this website out.

to protect your account information we cannot publish your Server names in public Knowledge Base. This information can be found on the HostPilot> Home > Exchange servers and settings page.

Note: Your ISP may have blocked SMTP traffic through port 25 in your area. If this is the case, add ":587" (without quotes) to the end of your Outgoing Mail Server Host Name, like this:

your_outgoing_server:587

This will ensure that outgoing SMTP traffic will go through alternate port 587 instead.

5. Complete the setup process. Click SAVE and wait for the iPhone to test your incoming and outgoing mail settings and connect to your mailbox.
