"Identify Yourself
When you start Swift, the second parameter is typically ignored by end-users. This is the identity of your web server. $swift = new Swift($connection, "[1.2.3.4]");"
Now, I have a web server which runs the web site and has SwiftMailer on it, but I have a completely separate SMTP server which SwiftMailer connects to.
Should the [1.2.3.4] number be the web server, or the mail server? (Yes I know it says web server, but I wanted to double check - from looking at the headers I suspected it should be the mail server, but I'm quite confused now!
Many thanks indeed
Ian
