# 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:

How to Install Git on Ubuntu 20.04

sudo apt update 

sudo apt install git

Create mysql user with all privileges

 CREATE USER 'newuser'@'localhost' IDENTIFIED BY 'user_password';

GRANT ALL PRIVILEGES ON *.* TO 'database_user'@'localhost';

Add Additional IP to Ubuntu VPS

Step-1:

add dns of your IP Pool or you can use

 /etc/hosts

for example:
xx.zz.yy.97 ip1-pool.example.com 

xx.zz.yy.98 ip2-pool.example.com 

xx.zz.yy.99 ip3-pool.example.com 

xx.zz.yy.100 ip4-pool.example.com

Step-2:

In Ubuntu beginning with version 17.10, you can find the network configuration in the file 

/etc/netplan/01-netcfg.yaml [in Contabo VPS]

/etc/netplan/50-cloud-init.yaml [in OVH VPS]

With this method you can assign additional IPv4 and IPv6 addresses to the interface eth0. Additionally to the main IPv4 address 192.51.100.10 and the first IPv6 address of your IPv6 network, you might configure the additional IPv4 addresses 192.51.100.42 and 192.0.2.23 and the additional IPv6 addresses 2001:0db8:2a02:c200:0000:0000:0000:0002 and 2001:0db8:2a02:c200:0000:0000:0000:0003 in the area addresses: below of eth0: . It is important to keep the correct indentation!
