[Dovecot] Mobile phone client detects 'PUSH' server
Does Dovecot really provide a 'PUSH' email service? The mobile phone client (standard with SonyEricsson C510, in this case) reported that the server (our Dovecot installation) offered PUSH email service. I hadn't seen that in the documentation that I'd read and had understood the client-server protocol to be a client-PULL service, in that the clients decide which folders to retrieve, and check what messages there are and fetch any new messages. The clients we've used so far have settings for frequency of these checks.
I didn't explore the option further, yet, being unsure whether there was a genuine PUSH service from our server or whether the phone was using a proxy somewhere (not ours) which would provide an intermediate fetch/aggregation/'pull then push' service of some sort - perhaps similar to the public offers from Yahoo etc.
regards, Ron

Dovecot supports 'IMAP IDLE' for quite some time. Given the fact the mobile client can handle this (few can), the client will be notified immediately. Searching for IMAP IDLE on the list will reveal more information.

Astonishing. Is there anything it doesn't do ;)
(We've just been happily using Dovecot for a couple of years, very reliably, unaware of the richer features.)

Thomas, thank you, very much indeed, for saying what the feature is called. I'm certainly going to look at that.
Presumably we're last in line, here, I imagine everyone else is already using their ordinary mobile phones with Dovecot (at least, the SE models, which all seem to have this client). I expect that quite a few of the archived messages will deal with this.
Again thanks, Thomas, regards, Ron
