You may have noticed my email bouncing since 11am yesterday morning.
That is because my ISP was shut down by Bell Nexxia for failing to pay
their million dollar bill from 3 years ago. Anyhow their services have
resumed but I am in the processes of moving my business connection (this
one) over to a more reputable ISP so you may see my email bouncing again
for a day or two next week.
Regards,
Andrew

You need to publish it as a mail server, external ip to internal IP
Then you need to allow smtp in and outwith an allow rule, simple

The same configuration worked fine with my ISA 2000 (luckily I still
have that box and revived it until I figure this one out).
Exchange is on a member server behind ISA. Internal DNS is on the DC and
it uses my ISP's DNS as forwarders. My external DNS is resolved at
NetSol.
I believe it's got something to do with the way I published the
Exchange.
There's contradicting articles out there. One says you just use the
"Publish a mail server" task and another says you need to do the
"Inbound SMTP", "Outbound SMTP" and "Outbound DNS" rules. First didn't
work (for
incoming) so I used the second one. I thought that was working but now
it appears it wasn't. For some reason though, it was working every once
in a while. I could send myself e-mails from Yahoo but not from MSN, for
example. Stupid me I wasn't watching the alerts. The exact phrasing of
the alert is: "Server publishing rule (Inbound SMTP) that maps <mail
server IP>:25 TCP to <external ISA IP>:25 for protocol [SMTP Server] was
unable to bind a socket for the server. The server publishing rule
cannot be applied. The failure is due to error:
0x80070034." Couldn't find anything about the error at M$.
And then there's all those detected "all port scan attacks" from my
internal DC. I guess I should just turn the "Intrusion detection" off.
Anyway, I think Jim's right: I should start from scratch and do one
thing at the time.
Can anyone tell me what the best article about publishing Exchange is?
(Including RPC over HTTP)
Thanks guys.
Steven
