Is my understanding of sendmail incorrect? I thought it was able to take
mail from the email client and essentially process through the net so that
as long as I have a network connection I am my own mail server able to send
directly to anyone else's mail server.
Here's an update: Through the Verizon DSL connection I can send and receive
mail normally. This means I can use smtp.earthlink.net to send mail. From
another LAN, connected via a shared T1, I am not able to send mail using
smtp.earthlink.net as I get a relaying denied error.
The problem isn't being blocked out of the LAN to the internet, it's trying
to send mail from my Earthlink account, which doesn't allow relaying through
their servers. If my understanding of sendmail is correct, and it could be
wrong. I can use it to listen to port 25 on my computer, or some other port,
as my own personal smtp server and it will send the email forward as long as
I have a connection to the net.
Am I misunderstanding this?
