Why do I have to direct to local smtp server?

Could someone explain the following? I have an application (Netvault Bakbone)
that has the ability to email reports on particular events. The email account
that I'm sending to is hosted by an external server at usa.net-my company
outsources their email. I was unable to send the report when setting the smtp
server in the application to usa.net. So, I set up SMTP (IIS was already
running) on the server this application is running on and specified that the
smtp server was now (E-Mail Removed). The email account I'm using didn't
change, (E-Mail Removed) but, whola, it's working. So, to summarize, I can't
specify an external smtp server but, rather, an internal that is able route
it correctly. How or why is this working?

does their smtp server require authentication maybe??

Good question but, no. I'm simply try to email the report to myself and it
won't transfer unless I point it to the local smtp server. Thanks, Erick

would the report come from the same ip address range as you normally use for
that account? some isp's will only accept mail from users from within their
own range of ip's.

Looks like you called this one correctly. I contacted USA.NET and they
advised me of the following.

Most of USA.net servers require authentication to send through our system.
If an account is not setup for your sending software and it cannot
authenticate, then ability to send must go through a different USA.net
server. Our Postmaster restricts traffic to specific approved IPs on that
server which allows sending without authentication. If you would like to
have the ability to send through our server, please send an email to our
Postmaster at (E-Mail Removed). Please include the outside static IP
address and a reason why the IP address needs to be whitelisted.

yep, that makes sense... standard anti-spam prevention.

p.s. if you keep running your own smtp server, make sure you do the same
thing! you should lock it down even further to only allow connections from
your specific ip address and block everything else.

Back up to the beginning at the first post.......

You are not supposed to set it to that server. You are supposed to set it
to *your* SMTP server not the destination's SMTP server.

That's right,...because that is the way it is supposed to work. The
software needs to know what SMTP server you are sending *from*,.....your own
SMTP server is the only thing that was to worry about what SMTP server to
send to at the other end,...not the Netvault software.
