Setting up a corporate email server for iPhone and iPod touch
Summary
This article explains the key steps for setting up a corporate mail server which can be accessed by iPhone and iPod touch. These key steps will need to be completed by the IT support team or network administrator to enable access from iPhone to the corporate mail server.
Products Affected
iPhone, iPod touch, iPhone 3G, Verisign
If you have or are setting up a Microsoft Exchange server, please see the iPhone Enterprise Deployment Guide for further information regarding the required configuration of Exchange for iPhone or iPod touch access to Mail, Calendaring, and Contacts. iPhone and iPod touch, running iPhone 2.0 software or later, allow for access to Exchange servers and data via Microsoft ActiveSync and EAS.
The following information, from Microsoft's TechNet Library, may be useful when setting up or configuring Exchange servers for iPhone and iPod touch mail access:

For non-Exchange mail server configurations, or for Exchange server access via IMAP, use the following settings to enable secure iPhone and iPod touch access:
Step 1
Open port 993 to allow email to be received through the firewall.
The proxy server must be set to IMAP over SSL only. SSL ensures that mail is securely encrypted during wireless transmission.
Step 2
As a best practice and for additional security protection, install a digital certificate on the server from a trusted certificate authority such as Verisign.
Installing a certificate from a certificate authority (CA) is an important step in ensuring that your proxy server is a trusted entity within your corporate infrastructure.
Step 3
Either port 587, 465, or 25 must be opened to allow email to be sent from iPhone.
Additional Information
When sending a message, iPhone automatically checks first for port 587, then 465, and then 25. Apple recommends opening 587 as the most reliable, secure port because it requires user authentication. Port 25 is considered to be the least secure because it's been around the longest and is subject to more attacks by hackers. It's also the port that some ISPs block by default to prevent unsolicited spam.
