How to disable old Yahoo email address?

How can I temporarily disable pop in Yahoo Mail Plus so I can check my mail on my phone?

• Apparently when mail is downloaded to a client via pop, the email is deleted from the server. Occasionally I am out of town and need to check my mail on my phone at yahoo. I forward emails to my yahoo account during that time. Now, however, with Yahoo Plus, emails will be deleted and sent to either an email client or another address. Why is there no option to disable the pop?

• Answer:

  There is no option to disable POP3 e-mail because you don't need to disable it. What you need to do is to use IMAP e-mail instead of POP3 e-mail, which does not require that POP3 is disabled. Configure your phone to connect by IMAP, rather than POP, to imap.mail.yahoo.com, rather than to pop.mail.yahoo.com. Use the same username and password as you currently do. This will allow you to read your e-mail without deleting it from the server. Alternatively, some e-mail clients are capable of downloading mail by POP without deleting it from the server. Check the settings on your phone, you might have this option.
