SMTP networking at shared server -
My website is hosted in a shared server. I want to send an email from my website to the email address of my website. (Using a shell script to execute on a shared server.)
I'm curious to know: whether the connection should be channeled externally through phone / DSL company or Is internally channeled by the server?
If externally, how can it be done internally?

Hello mail.modeman.com ... ... it will have to go through a "fake" loopback interface. That means, it will be taken through an internal path within the network stack.
You can take a packet trace through TCPDump or looking at the header in the distributed email.
