Time Limit for Filing Warranty Deed and Tax Sale Redemption?

HISTORY: We sold a piece of property in Mississippi in August, 2006 to a single man via Warranty Deed. Thereafter, we moved to Texas. In early April, 2011, we received a Notice of Forfeiture from the Chancery Clerk stating that the property had been sold at tax sale on August 31, 2009 and we had until August 31, 2011 to redeem same. This notice was originally sent to the property address and that address was scratched out and our current address in Texas was handwritten next to same. We discovered that the grantee never recorded the deed nor paid taxes on this property, although all tax bills were sent to the property address. We attempted to contact Grantee, but his last known phone number was no longer in service. We then called the Chancery Clerk and was provided with payment information to redeem this property from tax sale. We paid the back taxes, as well as 2010 taxes on the land which were also then delinquent. We have received a Release from Delinquent Tax Sale from the Chancery Clerk as well as a receipt from the Tax Collector for the taxes, fees and penalties which we paid.

QUESTIONS: At this point, could Grantee produce the deed and be granted ownership of this property after almost five years? If the answer to this question is yes, how do we protect our interest in this property for our payment of taxes, fees and penalties?
