Logon to your account at Siteground.

Open Site Tools for your website.

Go to Devs = SSH Keys Manager.

Enter a Key name (e.g. privatekey)

Generate a Password

Click the Create button.

Go to3dots=Manage IP access to limit the IP addresses that can use this connection.

Go to3dots= Private Key and copy it to your clipboard.

On your local machine, open your preferred Terminal

Browse to /path/to/your/privatekey

Create new file, call it myschool and paste the Private key.

Run the following commands

chmod 600 privatekey

ssh-add privatekey

Back in the Site Tools = SSH Keys Manager, go to3dots= SSH Credentials to discover the username and hostname to use.

How to install Composer in MacOS

Install download the composer using the following curl command in the terminal:

curl -sS https://getcomposer.org/installer | php

 
After the command, you will have composer.phar file in the current directory and the composer command is available as: 

 php composer.phar [composer commnad] 

In order to make composer available globally, you have to move the recently downloaded composer.phar to local user’s bin folder as follow: 

sudo mv composer.phar /usr/local/bin/

 go to /usr/local/bin folder . 

You can click Shift + Command + G to open the dialog to go to folder. move the recently downloaded composer.phar in the usr/local/bin folder. 

We want to run Composer with having to be root al the time, so we need to change the permissions:

 sudo chmod 755 /usr/local/bin/composer.phar

create a alias using command:

Next, we need to let Bash know where to execute Composer:

 nano ~/.bash_profile

Add this line below to bash_profile and save

alias composer="php /usr/local/bin/composer.phar"

and then run this command:

 source ~/.bash_profile

Finally, run: composer --version

Now, you can access the composer from the terminal simply using the composer command.

# Excite
#
# We have heard reports that Excite.com limits senders to 1,000 emails in a 10 minute period per IP during the day, but is unlimited between 1:00am to 5:00am MDT. While we cannot confirm these reports, here is what can be done in PowerMTA if you are having trouble sending to excite.com. Use the following settings:
#
#
<domain excite.com>
dk-sign yes
dkim-sign yes
backoff-max-msg-rate 100/h # Use with PowerMTA 3.5
</domain>

#
#The setting backoff-max-msg-per-hour will cause PowerMTA to take the total amount, divide it by 12, and send no more than that amount in 5 minute intervals over the hour. The number of recent delivery attempts is not kept in persistent storage, so re-starting PowerMTA resets the limit, possibly causing it to actually be exceeded. You may want to set it a little lower than 6000 to give yourself a buffer.
##Now for the tricky part.
#You will need to set the server to run the command pmta set queue mode=normal excite.com/* every night at 1am MDT (cron job in Linux or scheduled task in Windows). This will cause PowerMTA to go into normal mode, and send email in an unrestricted manner. At 5am MDT, schedule the command pmta set queue mode=backoff excite.com/* to run. This will put all excite.com email in backoff mode, and the above settings will go back into place.

#From the following page:

#It seems that Comcast has added some rate limiting based on your SenderScore (https://www.senderscore.org/).
#As such, The following configuration can be used (in conjunction with max-msg-per-connection and max-smtp-out from above), changing the rate based on your score and the data from Comcast抯 site:
