I want to allow sending emails through server B using an application hotsted on server A.for that I had to use "allow relay for privileged IP address". I added "mynetworks = 127.0.0.0/8, ip.Of.Server.A/24" to /etc/postfix/main.cf but nothing happens after restarting postfix,I'm still getting 550 5.7.1 relaying denied Error.

You need to add

ipofservera/32

By using a /24 it's assuming the network, and you don't want to allow a network to transmit, only a single ip.
