I use Google Mail as authentication and GMAIL Access..
No doubt it is a simple as that.. but on the DNS.. I forgot to add the TXT CODE to deter spam from originated or spoofed from my domain..
So I had to put into place a long line of SPF Records to ensure emails from my domains are not sent out other than being via GMAIL...
azrin.info. IN TXT "v=spf1 mx a ip4:2404:6800::/32 ip4:220.127.116.11/16 ip4:18.104.22.168/16 ip4:22.214.171.124/13 ip4:126.96.36.199/19 ip4:188.8.131.52/20 ip4:184.108.40.206/19 ip4:220.127.116.11/19 ip4:18.104.22.168/16 ip4:22.214.171.124/23 ip4:126.96.36.199/16 ip4:188.8.131.52/16 ip4:184.108.40.206/16 ip4:220.127.116.11/16 ip4:18.104.22.168/12 ip4:22.214.171.124/16 a:*.gmail.com a:*.gappssmtp.com include:gmail.com"
Darn Long rite??
What it means is.. for AZRIN.INFO Allow only Emails sent from SPF Records originating from (Google IP Addresses... so many") and allow emails sent from domains of GMAIL.COM and GAPPSSMTP.COM ... it's Google Apps SMTP Server btw...
Anything else... NO Way.. just delete and bounce.
Good luck to my users using outlook.

In the typical world, Ubuntu Server 16.04LTS installation takes about 35-70mins, depending on your internet connection but with the rapid deployment, it takes a few mins.
Typically, what you will need is Google Cloud Compute account which everyone is given $300 to try out, so you are never out of pocket. Some sites and even if you are an incubator, they give out $10,000 in credits... all the better.
Now, what to do.
Setup your account. You will need a debit or credit card to verify your identification.
Once that set up, go and check your quota limits. It's under Compute Engine > Quota Tab.
Note the CPU Limit per Region.
Now, create a Ubuntu Linux Engine, using the Max CPU Allowed (customise) and less RAM. Usually for a full account is 24vCPU per region.
50GB HDD will do fine.
Once it is setup , you are almost done.
Follow my instructions on how to install the Eth Coin wallet and miner.
I will strongly suggest you install GETH in your LOCAL PC as that is the wallet you will need to mine your coins to.
If you are too darn lazy.. copy these instructions (cut and paste works) into your SSH terminal.
sudo apt-get clean
sudo add-apt-repository -y ppa:ethereum/ethereum-qt
sudo add-apt-repository -y ppa:ethereum/ethereum
sudo apt-get update
sudo apt-get install cpp-ethereum
once it's all done, you are good!
Try this command to see if it works
ethminer -F http://ethereumpool.co/?miner=0.1@0x162c28e126a97d0009158fbda0ca93e6e9cc13d0@SomeMiner
it will take 20mins to first time download the DAG or Dagger file up...something like the blockchain. Replace my 0x162 address after 30 mins
Then it will run.
When it's all done.. go to EthereumPool.co to check on your miner. The miner address is the address you specified.
All Good? DO NOT CLOSE THE WINDOW.
It will shut down!
now... U need to make a clone of the disks to make the ultimate array.
One 24Core is nothing when U can run 5 x 24 cores. Yes..yr money will finish quickly...but worth it

Here is the thing... it is based out of UBUNTU Linux and it's under GPL, ie source codes are made free. However, they are extorting lazy people $39.90 for a download from GPUShack under the terms of Goat with Red Eyes , another word for broad day cyber rip off.
If you got a stable broadband and not lazy enough (you need to do some work and huge bandwidth anyway with any downloads), you can get things done in less than 25 mins, tops.
Here is the requirements:
Your mining rig with a good broadband connection.
HDD Raw Copy Tool to burn the Ubuntu
4GB Thumb Drive for the image
32GB or more Hard disk or even Fast Speed Thumb Drive.
In this scene, I use Sandisk 64GB USB 3.0 Ultra Flair with speeds of 150MB/s... I do have to warn you the THUMB DRIVE GETS EXTREMELY HOT!
You will need to be able to boot from USB in your BIOS.. so press F1,F10 , F8, F12 or DEL at boot up and select your options. Some Bios require you to EMULATE the thumb drive as a HDD, and in this case, the bigger one.
Installing is purely simple. Do Not Partition the Drive. Remove all the partitions, Create one Single Partition, and EXT2 Bootable Flag. This is where the drive gets HOT! Do NOT TOUCH IT!
Everything is in order.. Checked. Networking Etc working.
Start download UBUNTU SERVER 16 LTS version. It has no GUI and is far better and faster.
Add on the Networking, LAMP, SSH Options as it saves you a huge hussle later on.
Once installed, it will reboot. Remove the main USB leaving the 32GB one.
Login, and it will show you are now Super User.
Add a backup user say pirate with superuser options. Use this when U need to over ride on SSH.
command: sudo adduser xxusernamexxx
it will ask for password
user a hard one, a number plate ex SGT1234Y will do fine.
now for the hard part..
Read the Ethereum Pool How to.
Pretty much tells U how to do the miner.
You will need a wallet though... so if you do not have...
sudo apt-get install software-properties-common sudo add-apt-repository -y ppa:ethereum/ethereum sudo apt-get update sudo apt-get install ethereum
After that, U need to setup the SSH service.
Makes like super easy...
This is a tricky one.
apt-get install openssh-server
I imagine all accounts are super user, so all accounts need SUDO or SUPER USER DO
sudo nano /etc/ssh/sshd_config
Change the port number to something else.. say 9988
add a line MaxAuthTries 3
This prevents bruting
sudo service ssh restart
I am plainly lazy so I just SSH in instead and when it's all done... you can start mining.
command will be
ethminer -F http://ethereumpool.co/?miner=0.01@0x162c28e126a97d0009158fbda0ca93e6e9cc13d0 -G --high-cpu-load
its basically ?miner=speed@0xaddress -options
After U test it works... CLONE IT.
Use CloneZilla or something

You want that app but its geoloc to that specific country?
Its plain simple actually.
What U will need ..as google now verifies..
1) VPN into the country
2) Mobile number for access
3) Play store access
In this case I used UK as some apps will only work for UK accts.
Get a GiffGaff sim..cost is free but £10 topup..ask me if u need one... as the txt messages will get there.
Once U have yr sim activated...then do your thing.
Go to accounts.google.com n get a new acct. Make sure U VPN in...
It will ask for the number...
After that..ur all set

Block chain finance aka FinTech is almost similar to blockchain technology.
Think of it this way, I want to pay you x amount of this y currency but you are in z country. An example is you are in India paying a supplier in Kashmir Pakistan in Rupees (with bundles of 1000 rupee notes) but the other guy only accept Pakistani Rupees. So how do you do, either you send in smuggled notes, thru Hawala or remit in USDollars which will cost you as much as 20% in fees. Now with Indian Rupees not legal tender, you are in a huge mess.
So now in the cyber world, I will send in Bitcoin or thru paypal, but paypal will still eat 2.5% in exchange fees. In crypto world, there are no fees or very little such as 0.00000001 btc aka 1 satoshi for the transfer, which is shared to the pool. What will happen is you broadcast to the world, say Mr Rajah acct x1234567890asfgh send a digital check to Mr Ali acct 0987654321awawqq for 0.0011 btc and with the fee, starting balance 1.0011 ending balance 1.0000 for Mr Rajah and start balance 0 anf ending balance 0.0011 for Mr Ali.
Everyone on the network copies and concur with the transaction and its sealed to the ledger digital block 123456 digistamp 24nov2016.0000.11 with crc check digits xxggaaccexample created by the miners. Once clear and sealed, no reversal.
So this goes on and on.
The need to pay middlemen are less now as everyone has a copy of every transaction of the chain till this time.
It reduces the cheque, wire fees, transfer fees and time taken.
Banks cut the cost drastically.

I have to put this to rest.
You dont compare malaysia prices for the rent etc to singapore , worlds most expensive city.
Here is the comparision , like and near like for like.
Disposal hourly rates, RM500 per day, 8hrs , Hyundai Starex, 2.2 diesel in KL.
Uber black rm3+rm1.40/km+0.40/min.= rm3+ rm192 (time) + rm980(7hrs 100kmh driving)=rm1175 max.
UberXl@rm2.50+0.40min+0.70/km= 2.50+192+800= rm994.50
Car cost @ rm130,000 (sgd 43,000), fuel @ rm1.90 ($0.70) per liter.
Toyota alphard is sgd 200k or rm600k.
Toyota wish is sgd 120k or rm 360k
Fuel is sgd 2.25 or rm 7 per liter.
Disposal rates is $400 per day for wish, sgd 800 for Alphard.
So you see, you cannot pay rm8 for a singapore chicken rice mah..*(sgd4 min) and so the erp tolls are super ex..it cost as much as sgd27 (RM82) a trip from woodlands to cbd at peak....compared to klia to town of rm20....
If you want to earn sgd but with malaysia vehicle cost, go drive lah..the saman for illegal taxi service is a huge sgd20k fine...
I hope the LTA and TP arrest those "airport transfer" goons plying singapore roads. You are being watched. You enter as a private car...and act gangsters
Go on...I am not your saudara. You are plainly jahil.
You want me to charge your silly British Paki customer Rm500 a day and you take half? Go f yourself.
If you are a tourist coming to singapore via malaysia, watch out dudes. Your tour guide is putting you in hot soup.
