Topic: iOS 11 and SOGo
Just an FYI for iOS users. if you are running an iRedMail server and are supporting iOS devices you will need to disable http2 in your nginx configs so your users can reply and forward emails from the native Mail.app on iOS 11.
Came across this issue this weekend when I could not reply or forward any e-mails. From what I found Apple is working with Microsoft and there is also a bug opened up on SOGo (https://sogo.nu/bugs/view.php?id=4272).
Currently this is the only work around I was able to find until Apple can fix this.
Hope this saves some hair pulling.
