Exchange outgoing mail disappears

I have set up exchange on small business server 2003. Everything is working fine except the outgoing email.  The clients are using outlook 2003 and receive email with no problems.  Any thing sent out on the other hand just seems to disappear.  There is nothing in the que on the server in exchange manager and there are no error messages flagged anywhere on the way. It is as if the email goes out quite happy but never arrives and doesn't have the courtesy to tell me about it. i have looked through the knowledge base and found a similar problem answered but it doesn't cover mine.  Any ideas?

Check the exchange logs in \\exchangeserver\EXCHANGESERVER.LOG

There will be some record there.

A couple things.  Are you using a smart host such as your ISP or are you routing through DNS?

If message tracking is not enabled, enable it, and take a look for some of the messages you think are disappearing.  This can help narrow down where they are getting transfered to etc.

Do you have any AV software on the server, if so as a test try disabling that and send some mail to see if gets to the destination.

If you have the ISP as a smarthost then all mail will leave your server quickly to the ISP.  However now the ISP is responsible for NDR's, delivery etc.  Hard to tell what happens after it leaves your server.  As a test you may try routing email through DNS to see if it gets delivered.  If it does then you may need to call your ISP to figure out where your mail is going.

What are the error message you are getting?
Can you paste the relevant section of your Exchange Log into here so we can see what the box is saying.

The error says it could not be delivered in time.  The following is from the log but looks like rubbish to me :(

Sorry,

I thought I had replied but I have been having problems with my home ADSL (but that's another issue).

Your logs show that the emails are being bounced by the remote  server. So your emails are reaching the other company frontieruk.com but are being bounced.

I noticed your mails are going through zapto.org, is that your Smart host?

Does this happen to all outbound or just this company (frontieruk.com)?

I would get on to zapto and show them these logs as it proves that the emails are leaving your building but bouncing

No worries thanks for getting back to me.  I have no idea who zapto is.  The isp is btconnect and that is the smart host. that log was from an email sent from chris@frontieruk.com to sales@neponline.co.uk. Does that help any?

Just did. There was a few warns do you want me to post them? The domain frontieruk.com is being hosted by btconnect just now for the website. Would this be causing any problems? (The server an domain in the office is also called frontieruk. The mail is gong through btconnect just now until i can get this set up). I think this is a bit out of my league but it needs to be done :(

Have you spoken to BT?

Can you send another email to hedley AT digitalessence.net and then post the 4 or 5 lines from your Exchange logs that contain my email address.

Need toc heck that these mails are actually leaving your server.

Earlier you said the messages were being caught in the queue and that you found them. Where were they being caught.

When you send this mail, can you look in Event Viewer to check for any errors.

Have sent it now.  Message tracking says in the last line "Message transferred to c2bthomr13.btconnect.com through smtp" I'll let you know what comes back.  I haven't phoned bt as last time i spoke to them as soon as i mentioned exchange they said it wasn't their area of expertise (They call centre monkeys) and that they didn't have anyone that could help me.

Ok,

the fact that your server has connected to c2bthomr13.btconnect.com means that it has left your building and is now with BT. We can pretty much rule out any issues with your set up.

Speak to them and when they say 'Exchange is not their area of expertise', point out to them that it has nothing to do with your Exchange server and everything to do with thier smtp routing.

Just keep on repeating the same thing over and over again until they put you through to 2nd or 3rd level suppor.

Trust me, it works.

Update :Have changed from smarthost to DNS and  switched the authentication to EHLO without a user name or password an it appears to be working fine.  I think it will be a day tops though before i come across someones server that tells me to shove it cause i'm using authentication.  It appears to work just now but i'm sure there will be problems.  I'll let you know. Any thoughts at this point?

Sorry,

can we just recap,

you found all your outgoing emails where? On your server or BT's?
You are now using normal DNS?
You are now having problems because you are not using authentication?

Hi madcowz. I found all my emails in the queue on my server even though it said it had past it to bt in the message tracking centre.  They were just retrying again and again.
I am now using normal dns instead of the smarthost
it appears to be working but i can see problems coming from servers that don't allow an annonymous connection as just now there is no authentication.

Cheers for sticking with me through this by the way. :)

Just the normal HELO/EHLO with domain name should be enough.

Have you double checked your DNS settings using one of those online tests eg:

http://www.dnsstuff.com/ and type your domain name into the DNS report, first on left.

This will give you a very good breakdown of any issues with your dns

Also, what does your event viewer say when the mails fail, do you get any '504 need to authenticate first" SMTP protocol error' errors?

Have a good check of the event viewer and see if there are any mail related errors there.

YAY!!! It works! DNS all seems fine.  No problems in event viewer and the emails are happily flowing in and out.  Think the problem was definately the HELO/EHLO etc settings
