Hi,
I subscribed to this list recently and have been monitoring the messages. I
have a problem that I need assistance with and I believe this is the place
to get it. The problem may seem trivial or elementary but we have not been
able to correct it. Please be gentle with this newbie.
Please allow me to provide some background information. I work for regional
education service center and we provide email for 45+ districts in our
service area. We are running IMail 5.06 on an NT4 (sp4) server. The server
has a single IP address and each district is setup as a virtual host (BTW, I
didn't setup the server, hosts or accounts--I am coming to this after the
fact and trying to learn as I go). We are using the IMail database for user
accounts. We have approximately 6000 user accounts.
We have a regional network to connect all our schools. Each school has a T1
to the district that connects to a DS3 backbone out to our Internet POP. Our
network is part of a larger intranet that includes 5 other service centers.
We are using internal IP addressing with a PIX firewall that allows access
to the Internet. There are external IPs in the firewall that point to the
IMail server. The firewall is managed by our ISP.
The problem that we are experiencing has to do with mail coming from outside
our internal network. Specifically, one school district has users that
periodically cannot receive mail from external addresses. For example, a
teacher wants to send something from their home dial-up account (let's say
its an AOL account, [EMAIL PROTECTED]) to their school account
([EMAIL PROTECTED]). They will receive a "undeliverable by the postmaster"
error message. The thing that is really frustrating is that it seems to be
ONLY this one school district and it's not ALL outside mail. I spoke with
the district's technology coordinator the other day and he had received an
email from his sister who is an AOL user.
Does anyone have any ideas short of deleting the entire virtual host and
rebuilding it and all the users from scratch? Please be as plain English and
detailed as possible. I am still trying to get my feet on the ground with
this system.
Thanks in advance.
