I have a modem router, model is Technicolor TG588V, not a good product..however UPNP is enabled, static IP
Got the link you posted, but I dont understand where you put these settings as in DLINK home APP you cannot configure at all email.
Anotherthing I noticed, ok email is not working and even push notification, do I need to enable app background refresh on Iphone?
Many thanks,
Beppe
