Re: How to turn on iMAP for the iPhone

If they're talking about configuring your port forwarding at your router,
then you map the ports to your internal IP addresses.

I don't know if there's a list of IMAP VS settings available anywhere. The
default ones usually work okay - which setting are you thinking of in
particular? It should be set to listen to port 143 on 'All Unassigned' IP
addresses.

We were just using 25 for testing

This is still an issue although they have gone out and purchased a
Blackberry which we got working with exchange ok

Two issues are not clear, the ISP is saying we need to map the port to an
IP, should this be the public one or the internal one for the server

2nd, what are the correct settings for the imap virtual server ?

Thanks

IMAP
is only used for reading email, you see. You will need to be able to
telnet
externally on port 143 before you can use an IMAP client outside the LAN.
If it works internally, then there is no more that you can do at the
server
end - it's all down to your ISP and your firewall setup.

Thanks for the update

We worked on this yesterday with cBeyond, our ISP
They are using NAT and Port 143 is closed by default
They tried forwarding the port to both the public and internal IP
addresses
on the server but we could not telnet to either of them

Telnet works internally to 143 and externally to 25

We also checked the settings on the IMAP protocol, the IP on the
virtual
server is set to the public IP

Thanks
Chris

David Pogue'siPhoneFAQ states theiPhoneworks with corporate
Exchange
e-mail systems if the administrator turns oniMap. So I want to
turn
on
iMap
to support theiPhone. How do iturn oniMapwith Exchange 2003
Server?
I
thanks you.

IMAPis already enabled on Exchange 2003. From a PC on your
network,
try
this from a command prompt:

telnet yourservername 143

If you see anIMAPbanner message displayed, then the server is
ready
and
listening. Just close the CMD prompt when you've finished.

Lee.

I ran this step and it came up showing imap running. My firm
also
makes OWA available. However when I try and access using imap or
exchange setting on my iphone it cant find the server. Any
ideas?

Do you have access to the firewall settings? You need to make sure
that
port 143 traffic is being forwarded to the Exchange server. You
tried
the
telnet test from the LAN, I assume? The next step is to try it
from
the
Internet.

What do you mean by "make sure that port 143 traffic is being
forwarded
to
the Exchange Server" exactly. Are you talking about just opening the
port
in
the router/firewall or something else ?

The iphone documentation says to connect to imap.domainname.com or
whatever,
what about a DNS entry for imap ?
Thanks
Chris

Yes, the port must must be open at the firewall, but if you are using
NAT,
then you will also need to tell it where to send the incoming traffic.

It shouldn't be necessary to create a special DNS entry just for IMAP.
I
would just use an existing one, like mail.domain.com - or even just
the
public IP address.

Lee.
