Yes. In fact, one of the nice things about IMAPrev4 as a protocol is that the server is allowed (in fact, required by rfc3501) to notify the client if the mailbox size increases while executing any command, by sending an EXISTS response which the client is required to handle. IDLE is just a command that takes a long time to execute (specifically, until the client ends it or the server's time limit is reached) so that the server has to send EXISTS responses whenever mail comes in.

There are several scripts in the ports for generating SMSes from the command line, which you should be able to make use of. You'll need to choose something appropriate for your area.

I've searched the web and I can't find any information about how to make this work. I know it can be done with Exchange and ActiveSync, but I don't want to run any kind of exchange server. Hmm, something similar recently came up here in the thread Exchange ActiveSync account, and in both cases there seems to be confusion in the roles of the MTA, the MDA and the MUA. The MTA is only responsible to relay mail to it's destination, the MDA to store it somewhere and the MUA to retrieve it. The mail is delivered in a mailbox and once it reaches that mailbox it is not the MTA's nor the MDA's problem anymore. It just sits there until you can reach your mailbox and read it. Many people think that IMAP, POP3 and alike are part of the mail (MTA) system but they are not. They are completely separate systems designed for you to be able to access/fetch your mailbox(es) from a remote location. Remember that email was invented on multi-user systems so when you log-in to a machine via telnet, ssh or sitting on a terminal, you access your email directly from the mailbox, you don't need to fetch it to a remote location to read it. Anyway, if you want to take mail from one mailbox and send it to another location, you need to pop-it (regardless if it's pop, imap or what have you) and then re-send it to the new destination. This is usually not the work on an MTA AFAIK and you need to use other tools such as Fetchmail. Hope this helps, Alejandro Imass Thanks for any help, or even a point in the right direction.

My understanding is that Apple wants all persistent connections to the iPhone to go through them, so that there is only one connection. This is, putatively, for battery life issues. Every pushable client on the iPhone doesn't maintain its own TCP connection but works through an API and has to have their service approved by Apple.
