Steve Tasker, 43, hoarded the "staggering" collection at his home. for up to three and a half years at his house and kept almost 16,000 mail items in or behind his garden shed.
Tasker also wrapped the letters in plastic supermarket bags to try and keep them dry because he claimed he would deliver them once he had sobered up. But he never got round to taking the post to its rightful destinations.
Tasker, then a postman for 12 years, was eventually put under surveillance by the British Royal Mail last September, after reports from the public about mail not being delivered. On the day he was observed, he didn't start on his walk until noon at the earliest, finished about 2pm and had left more than 300 packets undelivered.
