If you have V10 For a POP account, you can go to “Menu / Settings / General” and remove the option to “Download messages from POP3 accounts at startup” under Synchronization as in the example screenshot below. Then save and close Settings.
You can then manually click Refresh when you want to check that POP mail account.
Also if you want to disable the POP account, click “Menu / Accounts” and click the “General Tab”. Then at the bottom remove the option “include when sending / receiving email” under Services.
