Re: mailbox disabled

Situation resolved. Your POP3 connector question made me realize that the
only working addresses were addresses that also had POP3 equivalents at a
third party e-mail hosting company. The original POP3 provider was still
being used as a backup. The customers MX records were set so that mail is
delivered to the office server first and then to the backup POP3 provider if
the office is down (power/Internet outage, etc). Long story of why we didn't
see what was happening but it turned out to be that the ISP was mistakenly
blocking port 25 on their network segment. We have no control over the
router and had checked previously with the ISP to confirm that they were
forwarding port 25. They were on the router but it was being blocked on that
network segment before getting to the router.

With there being only two accounts, and they appeared to start "working"
when we added the additional address (the additional address just happened to
match the POP3 account address) and since we had checked with the ISP several
times, we got tunnel vision thinking it was a server problem. We never
received NDRs from the POP3 provider, just from the senders' servers stating
that the mailbox was disabled. This threw me too - if I had seen NDRs from
the POP3 provider server, or a user/mailbox doesn't exist NDR, we would have
seen what was going on. As it was, we had slowly become convinced that there
was an issue with Exchange but had no idea what it was.

I stepped back today to see what the accounts that were working seemed to
have in common and saw that they were the only ones with POP3 backup. So I
started from the beginning -
user/e-mail accounts were correct on server
mail worked perfectly inside the network
confirmed again that port 25 was open - it was
attempted to telnet to port 25 from inside the network - connected
attempted to telnet to port 25 from outside the network - bingo - I couldn't
connect
Refocused on the ISP/ISP router and finally got the situation resolved.

The server had been working flaelessly the entire time.

Thanks for your time anyway.

Sorry, I see what you mean - my examples of firstname@xxxxxxxxxx on
the recipient side. My mistake with the examples.

To try and clarify (my mistake, not yours), their server only accepts
email for one domain - domain.net. The reciepient policy reflects
this. They are not trying to have, and do not want, any other domains
served and their are no other domains involved.

OK - that helps, thanks.


When the user accounts on the server were initially created the client
wanted first initial, last name. So the email addresses were
automatically the same. NONE of these would work and anyone sending
e-mail from outside the network would receive the "mailbox has been
disabled" NDR. Inside the network, life was good.

That is funky - it should have worked. You might want to post the actual
domain name in here.



As an example - if dallen was the login name then dallen@xxxxxxxxxx
would be the default e-mail address. When the e-mail didn't work
from the outside to those addresses, we also added additional SMTP
addresses in the form of doug@xxxxxxxxxxx For an unknown (to us)
reason, this worked with both of the 2 original accounts. They are
still successfully using the additional addresses and mail is still
being rejected at the 1stinitiallastname addresses stating that the
mailbox is disabled even though both doug and dallen type addresses
use the same mailbox. I have even tried deleting the original
addresses and then re-adding them - same result.

After a couple of weeks of trying to resolve through the newsgroups
and directly with Microsoft, we were told to re-install. Since the
added addresses were working, and there were no other apparent
problems, the client did not want to do this.

Don't blame them. I don't think you need to reinstall, anyway.

You're using SBS, so that may play a role here. Are you using the SBS POP
connector?


That is how things have been left for several months until other
employees have been recently given network and e-mail accounts. The
customer has been trying to manage the network and they created the
accounts. We weren't contacted again until it became obvious that
the new users weren't getting e-mail and anyone sending from the
outside was receiving an NDR.

The accounts appear to be correct but, with the new accounts, even
adding the additional SMTP address doesn't work. I can see nothing
glaringly wrong with the server, the user accounts, mailboxes or
Exchange. We have over 50 servers setup identical to this one with
no probelms. We have been working with Exchange servers since 5.5
and have never seen this.

Thanks again,

Doug

Not a silly question at all-

This error message was from my server(domain.com) stating that it
had been told the mailbox was disabled on the recipient
server(domain.net). Hope this clarifies my original post.

Actually, that doesn't really clarify it, alas. I wasn't referring to
mydomain.com - just that you mention domain.com & domain.net in the
*recipient* bits here. Let's start over.

What is in the recipient policy in Exchange on the SBS box in
questoin? And, what e-mail addresses are defined in this recipient's
mailbox properties?

All updates, patches, etc are up-to-date.

When sending email within the network, everything is fine. When
sending from the outside to several of the accounts inside (not
all) the following message is received-

Your message did not reach some or all of the intended recipients.
Subject: test
Sent: 10/4/2006 8:29 AM
The following recipient(s) cannot be reached:
mbennington@xxxxxxxxxx on 10/4/2006 8:30 AM
The message reached the recipient's e-mail system, but
delivery was refused. Attempt to resend the message. If it still
fails, contact your system administrator.
<mydomain.com #5.2.1 smtp;550 5.2.1
<mbennington@xxxxxxxxxx>... Mailbox disabled for this recipient>

User and e-mail accounts appear to be setup correctly - we have
over 50 servers configured as this one with no problems. The
mailboxes are not disabled - internal e-mail works fine. There
are currently only 4 users on this box. Two accounts are working
and two are exibiting this behaviour. The original 2 that are now
working had this identical problem when first setup but we
changed the email addresses from the default
firstinitiallastname@xxxxxxxxxx to firstname@xxxxxxxxxx and they
started working correctly although you will still receive the
error if you try to send to the original address (which still
exists on their user account). We tried this with these two
additional accounts and it didn't help.

I originally posted to the newsgroups with the first two users on
this system about 6 month ago (not sure which group - SBS or
Exchange) and after several replies it we could not find the cause
and it was recommended that the server be re-installed. The
customer did not want to do that and since the alternate addresses
were working nothing was done. Now that the company is growing
and additional people are being added, we need a resolution.

Any ideas?

Thanks,
Doug

Silly question, maybe, but the example address in the NDR is
somebody@xxxxxxxxxx - and in your description below that, you've
got somebody@xxxxxxxxxxx Do you use both domain.com and
domain.net, and, if so, are both of those domains set up in your
recipient policy, with the appropriate addresses set on each
user's mailbox?
