I am not 100% sure this is SOGo related but since there are others using similar/same setups I figured here would be as good a place as any to start. We are running SOGo 1.3.13 with a seperate machine running the modified z-push for email since our setup only allows port 80 and 443 to be open to the outside world. Ever since the upgrade of "iDevices" to iOS 5.0/5.0.1/5.1 we have seen issues with our users devices. Once they upgrade they are unable to pull email or calendar anymore. Also an odd thing happens and they are unable to even access their mail settings for that account. The settings just freeze and eventually closes. That is with setting up the full meal deal with email/calendar/contacts/reminders, I am currently wiping an iPad2 I have for testing to see if it does it on just calendar or just email. Has anyone else seen similar issues?

After some more testing it appears the issue is z-push. I was able to add the caldav stuff directly from the SOGo server to the ipad no problem. Two-way sync works beautifully. So it appears that with the iOS 5.XX upgrade they dropped/broke support for older activesync protocol versions. The z-push version we are running, and also the same thing was posted here on this list a month or so ago, was written in 2007. So now the adventure begins to try to setup a recent z-push that can do only email to our imap server. So once we have that setup we will be good to go on email and caldav. Unfortunately unless we can get z-push to work with contacts tied into SOGo then we will just have to go without carddav since we cannot open port 8800 to the outside world.
So in the end, sorry for all the noise, just trying to document what I can to make sure no one else has to go through the hoops I had to go through. And as always thanks to the Inverse guys for making a great piece of software!
