Did you now that is possible to get totally free pushmail on your symbian phone? All you pay for is data traffic if you use via GPRS/UMTS. And if you have a good data traffic plan it would be totally free. The solution works really great via WLAN, and on most GPRS/UMTS networks. Some operators however automatically close idle connections, but often this can be avoided by forcing the access point (AP) to give you a public IP-address. The only thing you need to get this working is have access to an IMAP server that supports the IDLE command, or to be able to configure your own server. This howto has three parts: Installing your own server, setting up a phone to use IMAP IDLE and getting your AP to provide a public IP-address.

Here I will show you how to install your own IMAP server, configure it, and get it running. I have chosen the cyrus IMAP server seeing as it's a quite good open source IMAP server that supports IMAP IDLE commands. I will be installing it on a debian system, configuring it to authenticate via /etc/shadow (locale brukere) and finally configuring exim to copy incoming mail to the cyrus IMAP serve
