Very interesting!
I'll disagree - most SMTP agents allow you to send mail if one of two
conditions are true:
1. You are a "member" of that ISP.
2. if not - you are sending mail to someone within that ISP's
namespace. (for example - "my" mailserver at foo.com can send mail to
YOUR servers at barr.com if I am sending to a valid user)
Have you checked your DNS settings? Are you using DNS at all? (on your
internal network?) Are you using DHCP?
Try this - connect w/o the STN box - verify that things work correctly,
and then open up a DOS window.
(win95, win98) type winipcfg /all
(winNT win2k) type ipconfig /all
This will show you what the COMPUTER thinks is happening - especially
for things like DNS, WINS, etc.
If your ISP's external DNS servers are not propigating thru to your
machine's network config - you're hozed.
If you're using DHCP, and do NOT have the DNS/WINS settings set in the
DHCP setup - DHCP can overwrite manual settings - leaving them blank!
(It happend to me & drove me crazy!!)
If you are using W2k, and have both internal and xternal DNS servers in
the DNS server list on the local machine, W2k can get confused. (if, for
example, the internal DNS is not set to check with the external DNS)
The security issue mentioned below should not matter, as you will get IP
address "X.X.X.X" on the external side - (which the upstream system
knows about), and as far as THEY are concerned, all communications comes
from that address. So - any IP mapping security should always work.
I think it's a DNS issue.....
