How to recover the name of a deleted disposable Yahoo email address

With yahoo!mail you can configure up to 500 disposable email addresses, which you can easily delete at any time. The name always consists of a base name and a custom part.

If you have deleted a disposable address and also forgotten its name, but now need it again to receive messages, there is a problem: without knowing the custom part of the address, you cannot easily recreate it. Unfortunately, yahoo!mail does not show which addresses you have used and deleted in the past.

However, this does not mean that Yahoo does not keep track of all email addresses that are somehow related to your account. If you have ever received a message on your disposable address, it may very well be possible to recover the name of the address using the method described below.

  1. Go to https://mail.yahoo.com/getmydata
  1. Under ” Contact data extracted from message”, click on Download:

You will be asked to enter an email address to be notified when the download is ready. This will take several hours.

  1. Once you get the notification that your download is ready, click on Download file.

Unzip the downloaded file and open ContactsData.json with Notepad (or any other suitable software, e.g. Notepad++).

Search the file for the known part of your throwaway addresses (the base name). This should give you the names of all your disposable addresses that have ever received a message.

Finally, recreate a disposable address with the same name.

A user-friendly desktop wallet for Namecoin (NMC)?

Yes, such a wallet exists, though it is still in beta: AtomicDEX (desktop version only) supports Namecoin (NMC).

You can even use the built-in “atomic swap” feature to trade your NMC, for example, for Komodo (KMD), which you can hold in the wallet and collect rewards or sell on many popular exchanges like Binance (affiliate link). Make sure you read the instructions first (found under Support). The atomic swap protocol requires that the maker and taker stay online and monitor the blockchains involved.

Exchanges which accept Namecoin can be found here.

Bootstrap file to synchronize your Dogecoin Core wallet faster

Update February 28, 2021: Dogecoin Core 1.14.3 has been released and significantly improves the synchronization speed. The method described in the original post below is no longer be necessary.


This article assumes that you have backed up your wallet and updated to the most recent version of Dogecoin Core (currently 1.14.2).

At the time of writing, you can get a torrent here which contains blocks until January 29, 2021. Note that it is not a single Bootstrap.dat file, instead it contains the blocks and chainstate directory.

You can find further information on the Dogecoin Discord (in the FAQ section), the Dogecoin Core GitHub and the Dogecoin subreddit.


Once synchronized, consider forwarding port 22556 to help the network. This should give you over a hundred connections instead of the usual 8:

This will, of course, create significant network activity as can be seen in Dogecoin Core under Help > Debug window > Network traffic. This is my traffic from just two days:

Edit: My Dogecoin wallet on a PC that was running 24/7 still went out of sync multiple times:

Let’s not forget that Dogecoin was created as a joke.

Edit 2: I do not recommend using the full node wallet (version 1.14.2) if you’re just getting started with Dogecoin. Consider using a simple mobile wallet like Trust Wallet.
