I have just sucessfully setup my iPhone to use a POP3 account to receive and SMTP to send using SSL over my home Wireless network using Exchnage 2003 and a self issued SSL certificate using Windows 2003 server. I have a Windows 2003 / Exchange 2003 server becuase i do a lot of developement and testing at home for both work and becuase i like to keep current.
If you have an Exchange server in the office and a wireless network you can conenct your iPhone to then shoudl work for you provided your IT will allow you to use POP3 and configure it with an SSL certificate.
I am working on a document step by step on how to do this but before i upload just wnated to check if anyone was interested in knowing how to do this as the last post in the thread is September.
All i have to do remaining is to configure my iPhone to use 3G or Cloud network to use SSL POP3 / SMTP but since i have it working internally on my hom network this should just be a case of makign some firewall changes on my CISCO ADSL router to allow SSL inbound to my exchange server.
If anyone wants the guide e-mail me at
matthew.dearden@networking-consultancy.com or repley to this post.
I couldn't get IMAP4 to work with SSL and when i did i couldn't display any of my mail messages.
