Here is the situation, upgraded network infrastructure, removed smtp relay
with linux sendmail to go with a simply Exchange Server 5 with IMC to do the
internet stuff. Setup another box w/ the same IP addy as the old linux
server running iMail from ipswitch to do listserver. Changed all DNS to
point to exchange server A record and MX record. Now, mail will come only to

relays it!! In other words, we change DNS to say the linux is gone and just
add a record for the new one. We have tried adding and removing MX records
for the iMial box and no difference. In the headers of messages that do get
through, the mail is going to the imail server (old linux's ip) and then to
the exchange server!! If there is a user setup on the imail side it works
but if not, no good. I need some help and could also use some sleep as this
is keeping me up all night!!! Thanks in advance...

Just because YOU changed the MX and A record in your DNS doesn't cause
all the other DNS's on the net to automatically flush their cache.
What was the expiration time on those records? One day? One week? A
month?

If you use YOUR DNS for name resolution and send the message does it
go to the right server? What does NSLOOKUP tell you when you use YOUR
DNS? What does it tell you is you use someone ELSE'S DNS?

And cleverly disguishing the e-mail domain as <domain.com> simply
prevents anyone from even TRYING to help you. Are you trying to hide
something? If you're posing the message from <mail.davegallagher.com>
you didn't succeed! But, still, <domain.com> IS a legitimate DNS
domain -- is it yours? Too bad <server.domain.com> doesn't exist
there.

Sounds like your IMS is misconfigured. What SMTP addresses do your mailbox
recipients have listed? What domains are routed inbound by the IMS?

Thanks for the grammar check and I am not trying to "hide" from anyone. If
you can read, you know where I am sending from. No matter.
I thank you for taking the time to reply.

No matter what DNS server we use, it still does not work. I am not sure when
our DNS is updated, I thought we changed it to 5 min. When you say use your
DNS, you mean the internal DNS that we setup right? THE primary DNS (ours)
and the 2ndary DNS (someone elses) are saying the same thing through DNS and
both fail with restest. I am not trying to hide the info...

I'm not asking when YOUR DNS is updated, I'm asking about the TTL on
the records your DNS sends to other DNS's. They'll cache the answer
until the TTL expires.

Quote:>When you say use your
>DNS, you mean the internal DNS that we setup right?

I mean the one that's authoritative for your domain. Whether you set
it up or your ISP maintains it isn't important. Where the NS points
and where the SOA lives is what defines which one is authoritative.

Quote:>THE primary DNS (ours)
>and the 2ndary DNS (someone elses) are saying the same thing through DNS and

Do they also *out when you use NSLOOKUP? The fact that the RESTEST
fails tells me that *somethings* wrong. NSLOOKUP will cough up a lot
more information on your configuration and the reason for the failure.

Quote:>I am not trying to hide the info...

So, what's the e-mail domain, the e-mail server names, the IP
addresses that have the problem?

Since you STILL refuse to post the information, but you persist in
asking for advice, I guess I'll post the data for you.

Quote:>mail server=elmerfudd.abtcampus.com
>A record to elmerfudd.abtcampus.com 206.228.84.72

A check of DNS shows that this is the correct information. The TTL on
that record is only 30 seconds, though. I think it'd be be better set
to 86400 (one day) or even 604800 (one week). If you started out at
86400 and waited more than a day the other DNS's should have flushed
the cache by now.

The MX records for <abtcampus.com> are as follows:

-> abtcampus.com.
type = MX, class = 1, ttl = 30, dlen = 13
preference 10, mail exchanger = exchange.abtcampus.com.
-> abtcampus.com.
type = MX, class = 1, ttl = 30, dlen = 14
preference 11, mail exchanger = elmerfudd.abtcampus.com.
-> abtcampus.com.
type = MX, class = 1, ttl = 30, dlen = 15
preference 12, mail exchanger = elmer-fudd.abtcampus.com.

All of those servers are aliases for the same machine:

-> exchange.abtcampus.com.
type = A, class = 1, ttl = 30, dlen = 4
inet address = 206.228.84.72
-> elmerfudd.abtcampus.com.
type = A, class = 1, ttl = 30, dlen = 4
inet address = 206.228.84.72

type = A, class = 1, ttl = 30, dlen = 4
inet address = 206.228.84.72

>MX to elmerfudd (10)
>Also an A to exchange.abtcampus.com for 206.228.84.72

IP address 206.228.84.72 and nowhere else.

>IMC "routing" setup- route the following inbound

Your IMS "Routing" tab should contain the following information:

Sent to: Route to:
abtcampus.com <inbound>

You don't want any <local-part> of an address in the routing tab, and

characters preceeding the e-mail domain either.

Quote:>I have tried a variety of these including just abtcampus.com by it'self
>Also tried to move the priority around (10) with no effect.

Since all your MX records resolve to the same address that will have
no effect.

Quote:>The old sendmail server was at 206.228.84.34 which is now the iMail server

That address isn't mentioned in any of your MX data. Here's the server
to which that IP address resolves:

-> 34.84.228.206.in-addr.arpa.
type = PTR, class = 1, ttl = 86400, dlen = 22
host = granny.abtcampus.com.

Quote:>and DNS server. elmer(.72) is also a DNS server and so is
>ns1.microserve.com. The old Linux box (206.228.84.34) seems to be getting
>the mail instead of the exchange server.

If it is it isn't anything that's happening because your of your DNS.

While it isn't serious (except from an administrative perspective),
why do you have your server's aliased with several different A
records? I can see the reason for <elmer-fudd> and <elmerfudd>, but
why <granny> and <speedy> (the other A record for the address
206.228.84.34). Also, is speedy.abtcampus.com a multi-homed server?
It's got two A records, 206.228.84.155 and 206.228.84.34 -- is that
correct?

A little bit more investigative work shows me that your problem isn't
with the ns1.microserve.net nameserver either:

QUESTIONS:
abtcampus.com., type = MX, class = 1
ANSWERS:
-> abtcampus.com.
type = MX, class = 1, ttl = 30, dlen = 15

nameserver = speedy.abtcampus.com.
-> abtcampus.com.
type = NS, class = 1, ttl = 30, dlen = 2
nameserver = elmerfudd.abtcampus.com.
ADDITIONAL RECORDS:
-> elmer-fudd.abtcampus.com.
type = A, class = 1, ttl = 30, dlen = 4
inet address = 206.228.84.72
-> exchange.abtcampus.com.
type = A, class = 1, ttl = 30, dlen = 4
inet address = 206.228.84.72

type = A, class = 1, ttl = 30, dlen = 4
inet address = 206.228.84.72

type = A, class = 1, ttl = 86400, dlen = 4
inet address = 207.44.0.1

type = A, class = 1, ttl = 30, dlen = 4
inet address = 206.228.84.155
-> speedy.abtcampus.com.
type = A, class = 1, ttl = 30, dlen = 4
inet address = 206.228.84.34

I DO see a problem with your server's hostname. It's not elmer-fudd,
it's elmer_fudd. Here's the SMTP server's banner:

220 elmer_fudd.abtcampus.com Microsoft Exchange Internet Mail Service
5.0.1460.8

This will cause problems for you when you SEND mail to other SMTP
servers (they'll reject the HELO/EHLO with a 501 error). Change the
"_" to a "-" and restart the IMS to make the change effective. You
might want to check the Site Addressing object's "Site Addressing"

I've sent you a message by connecting directly to your SMTP server.
Let us know what the RFC822 header's look like when you revceive the
message. The "Received:" headers should tell us how things are going
where.
