My mail server works fine. I have been able to send and receive mail for months. However, I've noticed that I don't seem to be able to send mail to @loudeye.com. When I do, the message just sits in my queue and I eventually get a delay of notification message. I have been able to send mail to the recipient using other mail servers.

Even if you don't know the answer, any hints on how to debug what is wrong with the outbound connection would be appreciated... i.e. is it possible to turn on an outbound SMTP log?

Have you done a tracert to loudeye.com from the internetconnection your E2K server uses? Occasionally the ISP's get some funky routes going.

------------------
Where are we going and why am I in this handbasket?

I was able to telnet to port 25 of mail.loudeye.com from my E2K server and manually submit a mail message that the recipient received.

I can still see the messages sitting in my E2K queue. When I look at the properties of the messages, it says that there are "0" delivery failures yet the messages just continue to sit in the queue and refuse to be delivered.


The traceroute seems reasonable:

Tracing route to unter.loudeye.com [216.10.241.2]
over a maximum of 30 hops:

I am having the same problem with certain domains. This happens when the DNS records are set to a CNAME and not an A record. Here is the MS Technet article: Q153001.

Microsoft is developing a patch for this, but it is not out. You may be able to call them and get the patch. There are two ways around this, one is to forward your mail to your ISPs smtp server or setup the dns entries your self for the domain having a problem.

Hope this helps.

Vincent.

I am experiecing about the same problem. However, I don't think the issue is the sending server rewriting the To: field, as Q153001 suggests. By watching the firewall logs, I can see that the server makes no actual connection attempt despite saying it does. This is confirmed in the SMTP logs on the server, which show no activity with the remote server; there should at least be a record of it rejecting the modified recipient.

Is there a way to set up my E2K server to send all outbound mail to that domain via an external SMTP server?

I.e. I know how to route all outbound mail through an SMTP server, but I'd rather only route mail to "problem" domains.

I'm having this same problem. I cannot send email to some domains (just a few) while I can do this from HotMail or other servers.

However, after a few weeks, the problem sometimes disappears for some domains while new problems can arise with other domains. This is till just a handfull I have had this problem with, but still.

Anyone found a solution - or knows an ETA for a fix from Microsoft?

My users are (to say the least) not happy about this, so any kind of ideas would be very welcome

Thanks,
- Sam

In the System manager / Virtual SMTP Server set up a smart host (something like smtprelay.yourhost.com), then itt will work fine.

Before doing so, check with your ISP to allow You using their smtp server for relaying.

That really is not a solution to the problem... there must be a good reason why Exchange itself cannot send mails to these domains..

In any case, we do not have an ISP. It's a university network where each faculty runs its own part of the network. There are no global SMTP servers avilable to do this...

I think I've found a work-around until Microsoft addresses this issue.

1. Turn off external DNS servers for the Virtual SMTP Server, if you're using them. This forces Exchange to go thru the regular TCP/IP stack lookup procedure.

2. Use NSLOOKUP to find A) the FQDN that the MX points to and B) the final IP address to which your messages will be delivered.

3. Create an entry in the server's HOSTS file that associates A and B from the previous step.

This has the effect of short-circuiting the alias record in the DNS tables, making Exchange think they're configured the way they should be.

Why wouldn't the FQDN the MX record points to be where my emails will be delivered?

Is this problem really about Exchange sending to the wrong IP?

Or is it just because Exchange cannot resolve the FQDN of the MX address and that by doing this I'm doing that for it once and for all?

Of course, this way - if the receiver changes IP - it is not updated automatically. But if it works, I guess it's our best choice.

The MX record points to an alias because whoever configured the DNS tables didn't do it correctly.

The issue is that Exchange simply isn't resolving the addresses correctly. What I found from my workaround is that this all goes away if you disable the use external DNS servers.

At any rate, Microsoft has finally released the patch: KB article Q280794.

Enjoy!

Yes, the fix is available, but not for download

Hopefully it will be soon. I cannot afford a support call on this, but perhaps this will be included in Service Pack 1 for Exchange...

Thanks!

Please send it this way as well. I really need this fix, but I don't need the xxx$ bill from MS for a support call...

TIA,

If I knew how to make a link out of this I would. Sorry! This has all the latest patches and downloads including the one you all are looking for. The patches fixed the same problem on my machine.

I think there is a separate bug in the DNS (rather than Exchange). I see "SERVFAIL" returns to Exchange from DNS for lookups which have certain nesting characteristics (and no useful glue records).
Anyone found that this fix has not sorted their problems?
Incidenatlly, the reason mails that thus can't be delivered but then go "eventually" is that the Win2K DNS sometimes does work because it occasionally receives additional non-authoritative A records (for a name server) for MX query answers that would othwise require another nesting level. This can happen if the server queried changes, or if the queried server has had to lookup that A record itself for some other reason (it may be have a different role for a different, but somehow related, domain).

I am having exactly the problems you are all describing - I have installed SP1 which is supposed to fix this problem but it has not fixed it.

Anyone else still having this problem?

Thanks,

Simon.

Really no one else is having this problem?

Mail to about 4 different domains is bouncing.
