Look in Settings at the Incoming server. It will have pop or IMAP in the server name.
Take a look at this. It's a step bv step walk-through on settled up filters in Gmail. If you're not working with Gmail the concept is th3 same and there's probably an online tutorial.

What is the incoming server name? Might still tell me what the account is.
What email service is it? Gmail, private domain or?
??? I don't get it. You haven't given the name of the incoming server yet, or even whether the account is Gmail, Yahoo, Hotmail, a private domain or? Without more information there's nothing more I can do for you.
Not sure you can manage the labels from the mobile site. You'll have to either log in through a computer or if your phone/browser supports it, you can request the Desktop Version on your mobile (usually you'll need to either re-load or re-enter the gmail address for it to work as the mobile version has a different URL).
