Hello,
The amount of time required to keep a Yahoo Mail account active and not deactivated and/or permanently deleted varies of time.
This is especially important for users that expect their forwards and/or pop & imap access to work forever.
As of this posting Yahoo will permanently delete your account if you do not login for 12 months.
Play it safe and set a reminder to login to your Yahoo Mail once a month.
