I have been assigned a task to separate email server and application server. I have little knowledge of server. I am using PHP. Earlier I use to send using phpmailer class. Now I have been asked to implement using PEAR and separating email server and application server. I have been told that we need to provide only the IP of the email server from the application server while sending email from the application server. Please suggest me I don't know how to proceed with it. Thanks in advance
