You really just need to test and see which ones work.
Also please keep in mind that when you cannot blink through a portal, sometimes you can DC as you run into it, and then log on and walk right past it.
Again, this depends on the portal. For example, the Zul'Farrak portal can be DC'ed through, while the Scholomance one has an invisible wall behind the portal.
Happy exploring.
