Most proxies will close open connections where no data is flowing in either direction after a few minutes, but for 'push' to work properly, you need to allow these to remain open for up to 59 minutes. Closing them prematurely for clients that use push (which is usually lowest in bandwidth and latency) means this will break. This means mails will be delayed.

Thanks for pointing out the config setting. I thought there was one some where, I just wasn't looking in the right place for it. I've reverted my changes and set the use_ssl option to 1. That did the trick.

Also, I'll check my timeout settings on the proxy and see if they are large enough. So far I haven't really noticed any issues, but I'm just using it on my own phone so far, so maybe I've just been lucky.
