ot: testing smtp 587?

I am currently traveling, using cell data and Wi-Fi as available, whenever I wish to send some photos, I try to use (free) Wi-Fi to save my prepaid cell data, it seems some Wi-Fi points do not allow access on port 587, so, my emails stay in out basket, then get sent on cell data, so, an of topic question:

Is there some way to easily test port 587 availability?
