Got a real problem with exchange 2007 which is making me look bad!

Basicly it works fine most of the time, but there is one company we have dealings with whose emails are never recieved by a certain employees mailbox.

For example, the company has email me and it works fine, but when they email my boss it never appears, they dont get a NDR either, it just vanishes.

Message tracking shows nothing, so I'm not sure the messages are even hitting the server.

I got the company to telnet to our exchange server and send an email that way and nothing has come through. I've also telnet'd into the server and sent a few emails, only one of which has come through with a huge delay (is this normal/another problem/related?)

We recieve loads of emails from other domains all the time, just this one in particular.

Any help muchos appreciated!
 
Cheers, I have a feeling it might be a problem with their DNS records, or a cached record in an email client, see we changed from a hosted email solution to and in house one a couple of months ago but kept the domain name the same to save everyone having to change emails.

Just checked and emails from this customer seem to be going to our old hosted server.

If you receive some mail from them, but not others its unlikely to be an SMTP issue surely? i.e their mail either routes through their own SMTP box and onto detsination or thru an ISP's; either way would mean no mail at all.

You sure it aint PEBCACK at their end, and the chap sending the mails is using an address you no longer support? Maybe a domain you no longer service since you changed server? maybe an alias no longer setup for the mailbox?

If it isnt hitting your server, then it isnt getting their which means the domain wasnt correct when they sent it, or alternatively you have stopped servicing a domain you used to have.

Edit: Just re-read your mail. If you dont receive any mail from them, then its a DNS problem at their end. Tell them to pull the DNS records and see what it says for MX.
