Hi, was looking for push email recommendations, I am using PPC2003 on a ipaq 6356 and am looking for a thoughts on push solutions, have looked at various ones out there, but I am looking for thoughts from users. I have my own domain (thus email server) and would want to use IMAP as I would want to access from both PC's and PPC without need for direct sync.

The Always-on app looks good but it is hard to tell without directly installing it if it uses the PPC inbox that stands (thus intergrates with SMS) or is a stand alone app on the mobile.

Thanks in advance

Cyril

What e-mail server are you running?

Thanks for the interest, my account is with kiwiwebhosts, I currently use IMAP with Thunderbird to access, as well as Squirrelmail. According to my cpanel interface the server is Linux Kernel (2.6.9-22.EL) but of course that does not detail what the IMAP/POP server is.

You could try emoze (http://www.emoze.com/) which is free - but you will need a PC (or at least the server) always on and connected so that the program can "push" to your Pocket PC.

There are other programs, but not free ones.

Comments are welcome here! I read about them before, and was contact by one of their engineers, but never used the software.

This one was just released: it's an email consolidation program, but I think it's only push with compatible IMAP server: http://www.geekzone.co.nz/content.asp?contentid=6400

IMAP more-or-less is a push email service, it sends you the message, instead of you checking for messages like POP. setup your PocketPC to use your mail hoster's IMAP server and you should be sweet assuming Microsoft have fully implemented IMAP in pocket PC (outlook is a broken IMAP client)

edit: my assumption was wrong :-\

IMAP is not push - it simply allows for folders and for a bery basic synchronisation. There's a push IMAP standard, but so far only a very few companies implemented it.

Also, you would be lucky to find an ISP with IMAP. Because POP3 clients download messages and delete from the server, while IMAP uses space on the server, many ISPs won't provide this functionality - otherwise they would have to continuously invest in disk space.

And yes, Pocket Inbox implements IMAP.

Take a closer look at the protocol freitasm:
http://en.wikipedia.org/wiki/IMAP
http://tools.ietf.org/html/3501#section-5.2

IMAP pertains that an email client should be ready to receive a notification of a new email. (much like exchange & push email) This works and I use it every day.

IMAP provides alot of functionality such as shared email folders, serverside email searches and even shared calendars when using UW-IMAP.

"Very basic synchronisation" ?? I have used it to replace Exchange.

At any time, a server can send data that the client did not request. Sometimes, such behavior is REQUIRED. For example, agents other than the server MAY add messages to the mailbox (e.g., new message delivery), change the flags of the messages in the mailbox (e.g., simultaneous access to the same mailbox by multiple agents), or even remove messages from the mailbox. A server MUST send mailbox size updates automatically if a mailbox size change is observed during the
processing of a command. A server SHOULD send message flag updates automatically, without requiring the client to request such updates explicitly.

The server notifies the client of changes in the mailbox. The client must then request a sync action. There's no push - the server notifies the client of a change in mailbox size.

There's a new protocol being worked, called P-IMAP (http://db.org/2004/02/12/push-imap/). This one introduces true push e-mail, but not many implementations are available.

More here: https://datatracker.ietf.org/public/idindex.cgi?command=id_detail&id=11517 and http://en.wikipedia.org/wiki/Push-IMAP.

Well I did say "more-or-less" push email :-)
It works for me in the same way Exchange and Push email would though, so I am in no hurry to buy an Exchange server.

When you say "the client must request a sync action" that's not like clicking the send-receive email button or a polled email check. The client automatically receives the new email after the server sends the message.

For me, it just works and your new email appears at the top of your inbox as soon as it has been passed to the IMAP server by your SMTP's LDA

It is not true push for sure, but thats semantical considering it does the same thing.

EDIT: on pocket Inbox (HTC Apache WM5) the IMAP client will disconnect from the server after receiving email. This effectively disables IMAPs email notification feature. Proper IMAP clients (evolution, thunderbird, etc) keep the connection to the server alive so as to receive new emails. Thumbs down Microsoft you broke yet another great feature of an open, industry standard in favour of un-interoperable proprietary rubbish!

Guys, thanks for all your suggestions, after looking at all the options, I had already decided a couple of days after my first post to just setup the PPC with a half hrly poll in under IMAP. This seems to work just fine, I will be checking out how much traffic that comes to after a months use.

I have my own account and domain that runs IMAP, I normally use Squirrel mail as my normal client as I use at least four different PC's in the course of a day. The Squirrel webclient infact interfaces as a IMAP client with the mail server, so sync with the PPC under IMAP is working just dandy.

Once again thanks for your suggestions.

Cyril
