From a browser. Login to outlook.com website, go to option manage my account, look for email rules.
You can use outlook.com smtp server if you don't mind the reply to address shows outlook.com or a signature that says send on behalf of .... from outlook.com. If you have gmail account you can use their smtp server. You can also use google smtp server to send your ISP mail, but check if the reply to address is really your ISP email address. I don't think Yahoo allow access their smtp server from a mobile, but I haven't use their mail setting in years. Other online email check their policy on sending email from a phone.
